Welcome aboard, 18 00:00:55,080 --> 00:00:57,400 Speaker 3: by the way, thanks for coming today being with us 19 00:00:57,440 --> 00:00:59,800 Speaker 3: this weekend. One of the things I love about social 20 00:00:59,800 --> 00:01:03,000 Speaker 3: media is sometimes the best show topics come from the 21 00:01:03,040 --> 00:01:06,080 Speaker 3: comments section. You know, I put up a short Instagram 22 00:01:06,120 --> 00:01:09,800 Speaker 3: post this week at roninany and you'll find it talking 23 00:01:09,800 --> 00:01:13,280 Speaker 3: about engine oil, not brands, not hype, you know, not 24 00:01:13,400 --> 00:01:17,479 Speaker 3: my cousin's mechanics says this, but simply talking about, you know, 25 00:01:17,920 --> 00:01:21,679 Speaker 3: using the oil to manufacturer specifies for the vehicle from 26 00:01:21,760 --> 00:01:29,240 Speaker 3: the manufacturer, correct viscosity, correct specification, correct certification. Pretty basic stuff, right, 27 00:01:30,400 --> 00:01:33,039 Speaker 3: And boy, you guys started asking some really great questions. 28 00:01:33,080 --> 00:01:36,000 Speaker 3: And the big one that someone asked and a couple 29 00:01:36,040 --> 00:01:39,360 Speaker 3: of you asked this, I noticed, is hey, Ron, how 30 00:01:39,400 --> 00:01:41,440 Speaker 3: often should I really change my oil? Boy, you guys 31 00:01:41,480 --> 00:01:43,720 Speaker 3: just want to drum me into this argument every time. 32 00:01:44,920 --> 00:01:47,560 Speaker 3: And I said, you know, I can't really answer it. 33 00:01:47,560 --> 00:01:51,080 Speaker 3: It's hard to answer in the context of Instagram or 34 00:01:51,120 --> 00:01:53,680 Speaker 3: Facebook or car doctor page. So I said, you know what, 35 00:01:53,720 --> 00:01:55,600 Speaker 3: I'm going to turn it into an open for the show. 36 00:01:55,600 --> 00:01:58,840 Speaker 3: And here I am doing it. It is the million 37 00:01:58,880 --> 00:02:02,160 Speaker 3: dollar question because depending on who you ask, the answer 38 00:02:02,280 --> 00:02:05,720 Speaker 3: ranges anywhere from the old school three thousand miles, which 39 00:02:05,920 --> 00:02:09,560 Speaker 3: I don't agree with, to whenever the dashboard light comes 40 00:02:09,600 --> 00:02:11,680 Speaker 3: on and starts yelling at you, which I've heard it 41 00:02:11,680 --> 00:02:13,680 Speaker 3: across the board. I'm going to tell you how I 42 00:02:13,760 --> 00:02:15,400 Speaker 3: do it and how I look at it and this is, 43 00:02:16,600 --> 00:02:19,520 Speaker 3: you know, there's a lot of decades of doing this, 44 00:02:19,720 --> 00:02:22,280 Speaker 3: being in this business and fixing cars, both professionally and 45 00:02:22,360 --> 00:02:26,520 Speaker 3: as a hobby, because you know, the answer, like most 46 00:02:26,600 --> 00:02:31,400 Speaker 3: things in automotive repair, is it depends. So here's how 47 00:02:31,440 --> 00:02:33,519 Speaker 3: I look at it. First thing, you have to understand, 48 00:02:34,000 --> 00:02:37,320 Speaker 3: oil today is better than it has ever been. Modern 49 00:02:37,400 --> 00:02:41,160 Speaker 3: synthetic oils are phenomenal compared to what we use thirty 50 00:02:41,200 --> 00:02:44,280 Speaker 3: or forty years ago. The additives are better, the resistance 51 00:02:44,320 --> 00:02:48,399 Speaker 3: to heat is better, oxidation control is better, sludge resistance 52 00:02:48,480 --> 00:02:51,800 Speaker 3: is better. Engines are machined more precisely, and fuel control 53 00:02:51,840 --> 00:02:55,280 Speaker 3: systems are way more accurate than they've ever been. Everything 54 00:02:55,320 --> 00:02:58,280 Speaker 3: about the system is improved. But here's the catch nobody 55 00:02:58,320 --> 00:03:03,600 Speaker 3: talks about. Today are also harder on oil than ever before. 56 00:03:04,720 --> 00:03:06,800 Speaker 3: Think about what a modern engine does, and if you've 57 00:03:06,840 --> 00:03:10,040 Speaker 3: been driving twenty years, you can really sit back and 58 00:03:10,040 --> 00:03:14,359 Speaker 3: look at this analysis twenty years or longer. Turbochargers, direct injection, 59 00:03:14,560 --> 00:03:18,720 Speaker 3: variable valve timing, cylinder deactivation, start stop systems. 60 00:03:18,760 --> 00:03:19,400 Speaker 2: I mean we could. 61 00:03:19,800 --> 00:03:22,040 Speaker 3: I could spend twenty minutes talking about each one of 62 00:03:22,040 --> 00:03:26,440 Speaker 3: these systems. Smaller displacement engines. The engines are getting smaller, 63 00:03:26,440 --> 00:03:29,880 Speaker 3: and they're making huge horsepower. Huge horsepower out of a 64 00:03:29,919 --> 00:03:33,919 Speaker 3: smaller engine. You're putting more stress on it, all right. 65 00:03:34,240 --> 00:03:36,200 Speaker 3: You put a smaller horse in the box to pull 66 00:03:36,240 --> 00:03:39,120 Speaker 3: the bigger wagon, and you feed it some vitamins. It'll 67 00:03:39,160 --> 00:03:43,760 Speaker 3: do the job, but it's working harder. Higher operating temperatures 68 00:03:43,800 --> 00:03:48,000 Speaker 3: are in this conversation, longer warm up times, tighter emission requirements. 69 00:03:49,200 --> 00:03:54,560 Speaker 3: So oil, it just doesn't lubrication anymore. Oil is hydraulic fluid. 70 00:03:54,880 --> 00:03:58,680 Speaker 3: It's coolant, it helps cool the engine, time and control. 71 00:03:58,720 --> 00:04:01,280 Speaker 3: It's part of the timing control for the mechanical for 72 00:04:01,360 --> 00:04:06,880 Speaker 3: the chain tensioners. It's turbocharger protection. It's variable camshaft actuation, fluid, 73 00:04:07,040 --> 00:04:09,680 Speaker 3: all those things that you guys want for performance in 74 00:04:09,720 --> 00:04:12,720 Speaker 3: PEP and ZIP and fuel economy. Oil is doing ten 75 00:04:12,840 --> 00:04:17,000 Speaker 3: jobs at once. So yeah, oil is better, but the 76 00:04:17,040 --> 00:04:21,320 Speaker 3: demands placed on it are dramatically higher. That's why I 77 00:04:21,400 --> 00:04:25,279 Speaker 3: tell people this all the time. The manufacturer's oil specification 78 00:04:25,400 --> 00:04:27,560 Speaker 3: matters more today than the brand name on the bottle, 79 00:04:27,600 --> 00:04:32,000 Speaker 3: and it does. It really does. That Dexos label, that 80 00:04:32,120 --> 00:04:37,360 Speaker 3: European Volkswagen spec that Chrysler MS rating, those aren't marketing gimmicks. 81 00:04:37,400 --> 00:04:41,159 Speaker 3: Those specs mean the oil has passed tests for timing 82 00:04:41,279 --> 00:04:47,000 Speaker 3: chain where sludge resistance, turbo protection of vaporation, of vaporation loss, 83 00:04:47,040 --> 00:04:52,360 Speaker 3: deposit control, and compatibility with emission systems. Now we'll talk 84 00:04:52,360 --> 00:04:56,479 Speaker 3: about drain intervals. Putting all that on the table. You 85 00:04:56,520 --> 00:05:00,880 Speaker 3: know what I generally recommend for a vehicle somebody plans 86 00:05:00,920 --> 00:05:03,720 Speaker 3: on owning long term, And this is where I have 87 00:05:03,760 --> 00:05:05,560 Speaker 3: to start, because you just can't say to me, hey, Ron, 88 00:05:05,600 --> 00:05:07,280 Speaker 3: what do you recommend from oil drain interval? I don't 89 00:05:07,279 --> 00:05:09,760 Speaker 3: know how long you plan on keeping the car, and 90 00:05:10,000 --> 00:05:12,200 Speaker 3: that has to come into the conversation. So if you're 91 00:05:12,240 --> 00:05:14,880 Speaker 3: planning on owning the vehicle long term, if you're sitting 92 00:05:14,880 --> 00:05:16,560 Speaker 3: there going, hey, I'm going to drive this car for 93 00:05:16,600 --> 00:05:21,719 Speaker 3: the next fifteen years, my oil change recommendation five months, 94 00:05:21,760 --> 00:05:24,760 Speaker 3: five thousand miles, don't care. Argue with me, prove me 95 00:05:24,800 --> 00:05:30,160 Speaker 3: wrong because that's my comfort zone. And people say, and 96 00:05:30,200 --> 00:05:34,120 Speaker 3: you do run the manufacturer says ten thousand miles. Yeah, 97 00:05:34,160 --> 00:05:37,359 Speaker 3: that's true. A lot of them do. And here's the 98 00:05:37,400 --> 00:05:39,640 Speaker 3: part that you guys just don't seem to want to hear. 99 00:05:41,080 --> 00:05:47,440 Speaker 3: Manufacturers designed maintenance schedules around ownership models, emissions compliance, operating costs, 100 00:05:48,000 --> 00:05:51,320 Speaker 3: and lease expectations. A lot of vehicles today are engineered 101 00:05:51,320 --> 00:05:54,640 Speaker 3: around the idea that the first owner mainly keep that 102 00:05:54,760 --> 00:05:58,880 Speaker 3: car three years. And that's a very different mindset than 103 00:05:58,920 --> 00:06:01,359 Speaker 3: the person's trying to keep Toyota Highland or until a 104 00:06:01,400 --> 00:06:03,240 Speaker 3: quarter million miles, until you get to that two hundred 105 00:06:03,279 --> 00:06:05,960 Speaker 3: and fifty thousand mile mark. It's different goals. So what 106 00:06:06,040 --> 00:06:07,760 Speaker 3: are your goals? So when you ask me, Ron, when 107 00:06:07,760 --> 00:06:09,120 Speaker 3: do you think we should change the oil? I'm going 108 00:06:09,160 --> 00:06:10,800 Speaker 3: to ask you what are your goals? What do you 109 00:06:10,839 --> 00:06:13,960 Speaker 3: expect to get out of this vehicle? Now. I know 110 00:06:14,000 --> 00:06:16,599 Speaker 3: there's going to be some Internet trolls out there that say, well, Ron, 111 00:06:16,680 --> 00:06:18,800 Speaker 3: I got ten thousand mile oil change intervals and I 112 00:06:18,839 --> 00:06:22,480 Speaker 3: got that quarter million miles. Congratulations, you're the person. You're 113 00:06:22,560 --> 00:06:24,919 Speaker 3: the one that got that. I have to speak to 114 00:06:24,960 --> 00:06:26,880 Speaker 3: the masses. I have to speak to the majority of 115 00:06:26,920 --> 00:06:31,520 Speaker 3: people that, in my opinion, we all drive such different 116 00:06:31,560 --> 00:06:33,960 Speaker 3: lifestyles and where we're going a lot of it is 117 00:06:34,040 --> 00:06:36,320 Speaker 3: just the hustle and bustle of every day, you know, 118 00:06:36,720 --> 00:06:39,800 Speaker 3: transportation to and from school, taking the kids to soccer games, 119 00:06:40,000 --> 00:06:42,880 Speaker 3: going to work. You know, I think there's less leisure 120 00:06:42,960 --> 00:06:45,279 Speaker 3: driving now than ever before because we're all just hustling 121 00:06:45,320 --> 00:06:49,039 Speaker 3: trying to make a buck and survive. So not everybody 122 00:06:49,120 --> 00:06:51,360 Speaker 3: drives the same. The person that gets in the car 123 00:06:51,400 --> 00:06:53,640 Speaker 3: and drives two hours across state to commute to that 124 00:06:54,080 --> 00:06:57,680 Speaker 3: big paying job is going to have a very different 125 00:06:57,720 --> 00:07:02,839 Speaker 3: oil drain, oil change, oil contamination experience in the person 126 00:07:02,880 --> 00:07:05,640 Speaker 3: that goes three minutes to the train station and the 127 00:07:05,680 --> 00:07:13,320 Speaker 3: family beater. Different goals. If you lease vehicles, honestly, you 128 00:07:13,360 --> 00:07:16,320 Speaker 3: can probably file the follow the oil life monitor. You'll 129 00:07:16,360 --> 00:07:18,679 Speaker 3: be the person that drives that vehicle for three years, 130 00:07:19,560 --> 00:07:22,760 Speaker 3: does puts thirty thousand miles on it, does three oil changes, 131 00:07:22,840 --> 00:07:24,600 Speaker 3: it hands it back to the manufacturer and go here's 132 00:07:24,600 --> 00:07:28,280 Speaker 3: your car. Because cars are like kids, all right. They 133 00:07:28,320 --> 00:07:32,680 Speaker 3: really are when they're younger. When when they're brand new, 134 00:07:33,120 --> 00:07:34,880 Speaker 3: a seven year old can fall from the top of 135 00:07:34,920 --> 00:07:37,080 Speaker 3: the stairs, get up, bounce up, Hey here I am 136 00:07:37,120 --> 00:07:41,840 Speaker 3: I'm great. But when you're thirty five, yeah, not so much. 137 00:07:41,920 --> 00:07:47,720 Speaker 3: When you're forty. When you're fifty, bones creek knees hurt, 138 00:07:47,880 --> 00:07:50,400 Speaker 3: it's not such a quick recovery. And cars are the 139 00:07:50,440 --> 00:07:54,600 Speaker 3: same way. So you know, change the oil, how you're 140 00:07:54,640 --> 00:07:56,960 Speaker 3: going to drive and own the vehicle, but be aware 141 00:07:57,280 --> 00:07:59,640 Speaker 3: when you go out to buy that used vehicle if 142 00:07:59,640 --> 00:08:04,200 Speaker 3: it was coming off lease, well, now don't you kind 143 00:08:04,200 --> 00:08:06,320 Speaker 3: of want to see what the oil change intervals were 144 00:08:06,360 --> 00:08:10,160 Speaker 3: and what was the service records? Doesn't that become right? 145 00:08:11,320 --> 00:08:13,720 Speaker 3: But you know, if you're leasing it, sure you know 146 00:08:13,880 --> 00:08:16,840 Speaker 3: do it by the oil life monitor because statistically you'll 147 00:08:16,840 --> 00:08:19,200 Speaker 3: hand that vehicle back way before the long term wear 148 00:08:19,200 --> 00:08:21,240 Speaker 3: shows up because you won't have that vehicle at seventy 149 00:08:21,320 --> 00:08:26,720 Speaker 3: eighty ninety hundred thousand miles. But if you own that vehicle, man, 150 00:08:26,760 --> 00:08:28,720 Speaker 3: if you're trying to drive this thing, like I said, 151 00:08:28,720 --> 00:08:33,160 Speaker 3: for fifteen years, boy, that changes the conversation completely because 152 00:08:33,240 --> 00:08:36,600 Speaker 3: what I see in the shop isn't usually immediate engine 153 00:08:36,640 --> 00:08:42,200 Speaker 3: failure from long drain intervals. What I see is cumulative 154 00:08:42,280 --> 00:08:47,319 Speaker 3: were timing change, stretched early variable valve time, solinoids, sticking 155 00:08:47,600 --> 00:08:50,360 Speaker 3: turbo oil feed pass is just coking up piston rings, 156 00:08:50,400 --> 00:08:54,560 Speaker 3: getting stuck oil control rings, sticking cam phasers, getting noisy 157 00:08:54,600 --> 00:08:58,920 Speaker 3: sledge accumulation in certain areas of valve covers and cylinder 158 00:08:58,960 --> 00:09:04,600 Speaker 3: heads that just star of oil PCV valve systems, contaminated 159 00:09:05,520 --> 00:09:08,360 Speaker 3: oil consumption issues beginning at ninety or one hundred thousand 160 00:09:08,360 --> 00:09:11,240 Speaker 3: miles instead of one hundred and eighty thousand miles. And 161 00:09:11,320 --> 00:09:13,680 Speaker 3: here's the part you guys miss. A lot of those 162 00:09:13,720 --> 00:09:17,240 Speaker 3: repairs don't look like oil problems. The customer comes in 163 00:09:17,240 --> 00:09:20,400 Speaker 3: with a check engine light, rough idle, turboro under boost, 164 00:09:20,880 --> 00:09:24,320 Speaker 3: a timing correlation code for a stretch chain oil burning 165 00:09:24,360 --> 00:09:27,840 Speaker 3: called startup rattle. Well, when you take the engine apart, 166 00:09:28,040 --> 00:09:31,640 Speaker 3: you can see the maintenance history written inside the engine. 167 00:09:32,000 --> 00:09:35,440 Speaker 3: I remember we had a customer, Bob drove an older 168 00:09:35,440 --> 00:09:39,199 Speaker 3: Toyota pickup truck. He was an over the road trucker. 169 00:09:39,600 --> 00:09:41,880 Speaker 3: When I got to work on this vehicle for the 170 00:09:41,880 --> 00:09:45,680 Speaker 3: first time, it was around the one hundred and fifty thousand 171 00:09:45,679 --> 00:09:48,120 Speaker 3: mile mark, and it needed a valve cover gasket, and 172 00:09:48,200 --> 00:09:51,360 Speaker 3: at the time it was probably every bit of twelve 173 00:09:51,440 --> 00:09:55,800 Speaker 3: years old. I took that valve cover off. I swear 174 00:09:55,840 --> 00:09:58,280 Speaker 3: I was looking at a brand new engine. Here was 175 00:09:58,320 --> 00:10:01,920 Speaker 3: a guy who changed the oil life clockwork every five months, 176 00:10:01,960 --> 00:10:04,559 Speaker 3: every five thousand miles, had a buck and a half 177 00:10:04,600 --> 00:10:07,160 Speaker 3: on it, and that thing was clean as a whistle. 178 00:10:08,520 --> 00:10:12,560 Speaker 3: I followed the life of that engine probably well actually, 179 00:10:12,640 --> 00:10:16,320 Speaker 3: until he stopped driving. He finally stopped driving. As you know, 180 00:10:16,360 --> 00:10:20,280 Speaker 3: he got older, and he stopped driving when he was 181 00:10:20,320 --> 00:10:23,079 Speaker 3: in his late eighties. And that vehicle had close to 182 00:10:23,160 --> 00:10:28,760 Speaker 3: three hundred thousand miles on it. And actually I know 183 00:10:28,800 --> 00:10:31,440 Speaker 3: the person that bought the truck. It needed another valve 184 00:10:31,480 --> 00:10:34,280 Speaker 3: cover casket. Took it apart, and it was just as 185 00:10:34,280 --> 00:10:35,640 Speaker 3: clean as the day that I had seen it the 186 00:10:35,640 --> 00:10:37,079 Speaker 3: first time, And it was just as clean as the 187 00:10:37,120 --> 00:10:39,319 Speaker 3: day when he first got it when it was new. 188 00:10:39,559 --> 00:10:43,280 Speaker 3: I'm sure because when you take an engine apart, you 189 00:10:43,360 --> 00:10:47,640 Speaker 3: see what's going on now before somebody calls or writes 190 00:10:47,640 --> 00:10:49,120 Speaker 3: me a letter and says, wrong, Well, I follow the 191 00:10:49,120 --> 00:10:52,440 Speaker 3: oil life monitor on my car's fine. Yeah, that's great. Yes, 192 00:10:52,880 --> 00:10:56,160 Speaker 3: And sometimes some engines tolerate things better than others, but 193 00:10:56,240 --> 00:10:59,760 Speaker 3: not all of them. And that's part of this conversation. 194 00:11:00,120 --> 00:11:02,800 Speaker 3: Has to be part of this conversation because I'm not 195 00:11:03,000 --> 00:11:06,320 Speaker 3: talking specific models. You call me with your model, we'll 196 00:11:06,320 --> 00:11:07,959 Speaker 3: have a conversation. I'll tell you where I think you 197 00:11:08,000 --> 00:11:09,959 Speaker 3: should where you should change your oil, what your interval 198 00:11:10,000 --> 00:11:13,880 Speaker 3: should be. But the majority of you for longevity, for 199 00:11:14,120 --> 00:11:18,600 Speaker 3: to drive at fifteen years, to take the best care 200 00:11:18,679 --> 00:11:21,640 Speaker 3: you can, the majority of you are five months, five 201 00:11:21,679 --> 00:11:23,240 Speaker 3: thousand miles. I'll tell you what. Let me pull over 202 00:11:23,240 --> 00:11:25,320 Speaker 3: to take a pause. When I come back, we'll continue 203 00:11:25,360 --> 00:11:29,559 Speaker 3: this conversation. And you know what, let's talk about oil 204 00:11:29,640 --> 00:11:31,679 Speaker 3: drain intervals. I'm running ade in the car. Doctor, I'm 205 00:11:31,720 --> 00:11:50,400 Speaker 3: back right after this, so you came back for more. Well, 206 00:11:50,679 --> 00:11:53,840 Speaker 3: let's continue the conversation about oil drain intervals. You know, 207 00:11:53,960 --> 00:11:56,840 Speaker 3: it's all about what the engine looks like when you 208 00:11:56,840 --> 00:11:58,160 Speaker 3: take it apart. And I can tell you that the 209 00:11:58,160 --> 00:12:03,359 Speaker 3: ones that do you know, more consistent oil earlier than manufacturers, 210 00:12:03,360 --> 00:12:06,720 Speaker 3: oil life monitors, those engines look better. And now you 211 00:12:06,720 --> 00:12:09,880 Speaker 3: got to talk about driving habits because oil drain interval 212 00:12:09,960 --> 00:12:14,319 Speaker 3: conversations have to have driving habits in there. Everybody thinks driving, 213 00:12:14,600 --> 00:12:16,480 Speaker 3: you know, on the highway is hardest on the oil, 214 00:12:16,520 --> 00:12:19,559 Speaker 3: and it's it's actually the opposite. You take a car 215 00:12:19,600 --> 00:12:21,160 Speaker 3: and put it in a New Jersey and you drive 216 00:12:21,280 --> 00:12:24,080 Speaker 3: flat out the California at a steady sixty miles an hour. 217 00:12:24,120 --> 00:12:26,600 Speaker 3: It never gets it never gets hotter than you know 218 00:12:26,840 --> 00:12:29,560 Speaker 3: it should, runs at normal operating temperature. It never gets cold. 219 00:12:30,200 --> 00:12:33,040 Speaker 3: You could probably you probably could put eight to ten 220 00:12:33,080 --> 00:12:36,800 Speaker 3: thousand miles on that vehicle without changing the oil. Steady 221 00:12:36,840 --> 00:12:40,360 Speaker 3: highway driving fully warms the engine, moisture burns off, fuel 222 00:12:40,400 --> 00:12:43,839 Speaker 3: dilution reduces. Right, there isn't a much you know, fuel 223 00:12:43,880 --> 00:12:46,440 Speaker 3: getting past the rings as they settle in and washing 224 00:12:46,480 --> 00:12:50,360 Speaker 3: out the oil. Oil temperature stabilizes, airflow is good, the 225 00:12:50,440 --> 00:12:52,840 Speaker 3: real oil killer. Let me just run down to the 226 00:12:52,840 --> 00:12:54,400 Speaker 3: corner store and get a quarter of milk. Let me 227 00:12:54,480 --> 00:12:56,160 Speaker 3: let me drive around the corner and get the paper. 228 00:12:56,240 --> 00:12:59,320 Speaker 3: Let me just run over to the supermarket and grab something. 229 00:12:59,360 --> 00:13:02,000 Speaker 3: All within five to ten minutes of driving. You know, 230 00:13:02,480 --> 00:13:04,560 Speaker 3: that little beater car that drives two miles to the 231 00:13:04,600 --> 00:13:08,480 Speaker 3: train station every day, that car may barely need breaks, 232 00:13:08,600 --> 00:13:12,000 Speaker 3: It may barely wear oil. I'm sorry, they may barely 233 00:13:12,080 --> 00:13:15,760 Speaker 3: wear tires. It just doesn't accumulate miles quickly. But it 234 00:13:15,840 --> 00:13:19,800 Speaker 3: is absolutely brutal on oil. It just it's tough on oil. 235 00:13:19,840 --> 00:13:24,880 Speaker 3: Why the engine barely reaches operating temperature. It gets, it starts, 236 00:13:25,200 --> 00:13:27,960 Speaker 3: it goes two miles and it shuts off again. Okay, great, 237 00:13:27,960 --> 00:13:30,640 Speaker 3: if it's July, well, I got to point out July 238 00:13:30,760 --> 00:13:34,040 Speaker 3: comes once a year and the rest of the time. 239 00:13:34,080 --> 00:13:36,280 Speaker 3: And again, where are we talking? Where do you live? 240 00:13:36,320 --> 00:13:38,720 Speaker 3: This radio show is you know natally syndicated and it 241 00:13:38,720 --> 00:13:41,160 Speaker 3: goes around the world on the podcast. So where do 242 00:13:41,200 --> 00:13:45,840 Speaker 3: we live? What sort of environment are we in? Condensation 243 00:13:45,960 --> 00:13:49,480 Speaker 3: builds inside the crank case, fuel contamination increases on that 244 00:13:49,559 --> 00:13:54,360 Speaker 3: short trip car, moisture accumulates, assets form, sludges start easier. 245 00:13:54,600 --> 00:13:57,319 Speaker 3: I'll never forget the first year I did the hot 246 00:13:57,400 --> 00:14:00,720 Speaker 3: rot my two door fifty five Chevy, and I was 247 00:14:00,760 --> 00:14:04,040 Speaker 3: so thrilled and excited, and I you know, we stored 248 00:14:04,040 --> 00:14:08,040 Speaker 3: it in the shop that winter and the following spring. 249 00:14:08,920 --> 00:14:10,720 Speaker 3: You know, the engine sat while we worked on the 250 00:14:10,720 --> 00:14:12,920 Speaker 3: rest of the car and got it together, and there 251 00:14:13,040 --> 00:14:15,000 Speaker 3: was something not right about the valve covers. I had 252 00:14:15,000 --> 00:14:17,480 Speaker 3: to change the breathers in them, and I pulled the 253 00:14:17,600 --> 00:14:21,320 Speaker 3: valve covers off, and the amount there was globs, that's 254 00:14:21,360 --> 00:14:23,720 Speaker 3: the only word I can think of, globs of water 255 00:14:23,760 --> 00:14:26,640 Speaker 3: that had condensed and formed inside the valve cover that 256 00:14:26,880 --> 00:14:29,000 Speaker 3: I sat there, you know, with a towel just just 257 00:14:29,080 --> 00:14:34,640 Speaker 3: sopping up the water condensation inside the engine. You know, 258 00:14:34,880 --> 00:14:37,400 Speaker 3: the older commuter car that does four cold starts a 259 00:14:37,440 --> 00:14:40,280 Speaker 3: day on tiny trips may need more frequent oil changes 260 00:14:40,320 --> 00:14:43,160 Speaker 3: than the family suv doing eighty on the highway every day. 261 00:14:43,360 --> 00:14:46,920 Speaker 3: So driving conditions count. Mileage alone doesn't tell the whole 262 00:14:46,960 --> 00:14:52,200 Speaker 3: story anymore. Operating conditions matter, climate matters, idle time matters, 263 00:14:52,320 --> 00:14:56,160 Speaker 3: trip length matters, turbo chargers matter, load matters. So when 264 00:14:56,200 --> 00:14:57,600 Speaker 3: you guys say to me, hey, Ron, why should I 265 00:14:57,640 --> 00:15:00,160 Speaker 3: change my oil? You know, I've got a list. It's 266 00:15:00,160 --> 00:15:02,840 Speaker 3: the questions I've got to ask. So I've got to 267 00:15:02,880 --> 00:15:06,120 Speaker 3: go with the standard five months, five thousand miles. It 268 00:15:06,240 --> 00:15:10,360 Speaker 3: fills a lot of gaps. And for everybody that's, oh, well, 269 00:15:10,360 --> 00:15:11,760 Speaker 3: we're looking at all the money, But no, you're not 270 00:15:11,840 --> 00:15:13,840 Speaker 3: wasting money because you've got to think about what else 271 00:15:13,840 --> 00:15:17,360 Speaker 3: an oil change does. A proper oil change, I'm not 272 00:15:17,440 --> 00:15:20,560 Speaker 3: talking about a quick lube and in and out, all right. 273 00:15:21,200 --> 00:15:23,080 Speaker 3: A quick loob is okay once in a while, not 274 00:15:23,160 --> 00:15:26,200 Speaker 3: as a full time thing. Show me a quick loob 275 00:15:26,280 --> 00:15:28,080 Speaker 3: that rode tests the car. Show me a quick glube 276 00:15:28,080 --> 00:15:30,200 Speaker 3: that checks breaks, that looks at tires, that wiggles the 277 00:15:30,200 --> 00:15:32,680 Speaker 3: front end. You know, that's to me what an oil 278 00:15:32,760 --> 00:15:35,080 Speaker 3: change is about. An oil change is meant to make 279 00:15:35,120 --> 00:15:37,840 Speaker 3: sure the vehicle is in proper working order and it's 280 00:15:37,840 --> 00:15:40,760 Speaker 3: safe to operate. If we're worried about going the distance 281 00:15:40,800 --> 00:15:43,080 Speaker 3: and we're concerned about the overall condition of the car. 282 00:15:45,280 --> 00:15:49,720 Speaker 3: As a vehicle ages, You've got to look at everything clean. 283 00:15:49,720 --> 00:15:53,840 Speaker 3: Oil becomes more important, tirewear becomes important because costs go up. 284 00:15:54,000 --> 00:15:56,880 Speaker 3: You've got to look at overall conditions, safety and reliability. 285 00:15:57,200 --> 00:15:59,800 Speaker 3: When was the last time the battery was replaced. It's 286 00:15:59,840 --> 00:16:02,160 Speaker 3: a it's a chance to say, stick out your tongue 287 00:16:02,160 --> 00:16:08,760 Speaker 3: and say ah, Older engines become less forgiving about maintenance neglect. 288 00:16:08,800 --> 00:16:11,320 Speaker 3: You know the well, I'm not doing the thirty I'm 289 00:16:11,320 --> 00:16:13,440 Speaker 3: not doing the sixty thousand mile service, I'm not doing 290 00:16:13,440 --> 00:16:15,720 Speaker 3: the ninety thousand miles service. And I tell customers all 291 00:16:15,760 --> 00:16:20,920 Speaker 3: the time, maintenance is cheaper than precision, and it means this. 292 00:16:21,120 --> 00:16:25,680 Speaker 3: It's it's far less expensive to keep an engine clean 293 00:16:26,440 --> 00:16:29,040 Speaker 3: than it is to try and repair a modern engine 294 00:16:29,280 --> 00:16:34,320 Speaker 3: once contamination begins, and modern engines are expensive. A timing 295 00:16:34,400 --> 00:16:38,400 Speaker 3: chain repair on some European or turbocharged engine can cost 296 00:16:38,440 --> 00:16:44,200 Speaker 3: several thousand dollars three four variable valve timing repairs expensive, 297 00:16:44,200 --> 00:16:48,000 Speaker 3: turbocharger repair expensive, all from something that may have started 298 00:16:48,080 --> 00:16:51,040 Speaker 3: years earlier as an extended oil drain interval. So now 299 00:16:51,080 --> 00:16:54,160 Speaker 3: I'm saying everybody around and change oil every three thousand miles. No, 300 00:16:54,840 --> 00:16:58,160 Speaker 3: I think that's excessive. But I think five months, five 301 00:16:58,160 --> 00:17:00,960 Speaker 3: thousand miles kind of fits that bill and kind of 302 00:17:01,000 --> 00:17:04,080 Speaker 3: fits the gap very nicely. And one thing I will 303 00:17:04,080 --> 00:17:06,320 Speaker 3: tell you about five month, five thousand mile oil DRAN 304 00:17:06,359 --> 00:17:09,800 Speaker 3: intervals that nobody seems to talk about is tire pressure. 305 00:17:10,359 --> 00:17:14,200 Speaker 3: That annoying tire pressure light. You put airon a tire 306 00:17:14,240 --> 00:17:18,919 Speaker 3: in January and you don't, you know, do tire pressure 307 00:17:18,960 --> 00:17:21,119 Speaker 3: because who's got a tire pressure gauge? Where can you 308 00:17:21,119 --> 00:17:24,200 Speaker 3: go find tire pressure at the corner garage? You can't anymore? 309 00:17:25,520 --> 00:17:27,359 Speaker 3: You know what. That's a big part of a proper 310 00:17:27,359 --> 00:17:29,960 Speaker 3: oil change is something as simple as tire pressure. So 311 00:17:30,440 --> 00:17:33,280 Speaker 3: five months, five thousand miles prove me wrong. Let's have 312 00:17:33,320 --> 00:17:35,879 Speaker 3: this conversation over the next couple of weeks. Hey, I'm 313 00:17:35,960 --> 00:17:37,920 Speaker 3: running any in the Car Doctor. Coming up next Aaron 314 00:17:37,960 --> 00:17:40,880 Speaker 3: Schaeffer from Standard Motor Products. We're gonna be talking about 315 00:17:40,920 --> 00:17:44,320 Speaker 3: fuel injectors and how they're made and what goes wrong. 316 00:17:44,119 --> 00:17:46,200 Speaker 2: And what goes right. So stick around. 317 00:17:46,240 --> 00:17:48,560 Speaker 3: Aaron Shaffer, Standard Motor Products is coming up next. I'm 318 00:17:48,600 --> 00:17:50,840 Speaker 3: running any in the Car Doctor. I'll be back right after. 319 00:17:50,680 --> 00:18:02,879 Speaker 4: This promises streets to the open road tonight. 320 00:18:04,640 --> 00:18:06,320 Speaker 2: We'll give you wrong and right. 321 00:18:09,200 --> 00:18:13,919 Speaker 4: He's a doctor, your advice, don't ride. 322 00:18:19,520 --> 00:18:23,480 Speaker 3: It was nineteen eighty eight was the last year that 323 00:18:23,760 --> 00:18:26,600 Speaker 3: carburetors appeared on production vehicles in the United States, so 324 00:18:26,640 --> 00:18:28,639 Speaker 3: it's been a while ever since. 325 00:18:28,680 --> 00:18:28,840 Speaker 2: Then. 326 00:18:29,160 --> 00:18:33,399 Speaker 3: Vehicles are or their fuel systems are powered by fuel injectors. 327 00:18:34,160 --> 00:18:36,639 Speaker 3: And it's a big point and it's a it's a 328 00:18:36,680 --> 00:18:38,879 Speaker 3: conversation worth having about how do we take care of 329 00:18:38,880 --> 00:18:42,960 Speaker 3: fuel injectors, What makes injectors go bad? What keeps injectors good? 330 00:18:43,600 --> 00:18:45,760 Speaker 3: And it's something we're going to focus on in our 331 00:18:45,800 --> 00:18:48,680 Speaker 3: next segment as we're joined this hour by Aaron Schaeffer. 332 00:18:48,720 --> 00:18:51,399 Speaker 3: He's with Standard Motor Products and we're happy to have 333 00:18:51,480 --> 00:18:54,360 Speaker 3: him back. This is his second time by popular demand. 334 00:18:55,160 --> 00:18:57,000 Speaker 5: Awesome, awesome, Yeah, thanks again for having me. 335 00:18:57,240 --> 00:19:00,320 Speaker 3: You know, drivers may not know, right, but it's the truth. 336 00:19:00,400 --> 00:19:05,359 Speaker 3: We haven't had a carbureted vehicle in forty some odd years, 337 00:19:05,480 --> 00:19:09,480 Speaker 3: maybe closer to fifty. And everybody's fuel injected now and 338 00:19:09,520 --> 00:19:12,440 Speaker 3: then today in today's car, So you know, what exactly 339 00:19:12,720 --> 00:19:15,960 Speaker 3: does a fuel injector do you know what are we 340 00:19:16,040 --> 00:19:19,000 Speaker 3: counting on it to do? Correctly in order to keep 341 00:19:19,080 --> 00:19:20,200 Speaker 3: that car running and running. 342 00:19:20,200 --> 00:19:24,880 Speaker 5: Well, yeah, Ron, I think the easiest way for people 343 00:19:24,960 --> 00:19:28,719 Speaker 5: to get their mind's eye around what it is is 344 00:19:28,760 --> 00:19:32,320 Speaker 5: it's little, largely mechanical device and it's going to take 345 00:19:33,400 --> 00:19:37,280 Speaker 5: raw fuel and dissipate it. It's going to put it 346 00:19:37,400 --> 00:19:42,360 Speaker 5: in a mist like pattern, the correct mist like pattern 347 00:19:42,680 --> 00:19:47,160 Speaker 5: right with the correct spray angle for fuel atomization, so 348 00:19:47,240 --> 00:19:52,119 Speaker 5: you have correct and complete combustion and the amount of 349 00:19:52,160 --> 00:19:55,000 Speaker 5: fuel it's going to meter and the pattern at which 350 00:19:55,040 --> 00:20:00,000 Speaker 5: that fuel is dissipated is absolutely critical to engine perform. 351 00:20:00,480 --> 00:20:02,600 Speaker 3: You know, It's sort of like I always think of 352 00:20:03,040 --> 00:20:06,080 Speaker 3: I think of injectors in April. April is fuel injector 353 00:20:06,119 --> 00:20:08,159 Speaker 3: a month in my mind because I watched the rains 354 00:20:08,160 --> 00:20:11,080 Speaker 3: in New Jersey, Okay, and you know, we get fine 355 00:20:11,119 --> 00:20:14,920 Speaker 3: missing rain, we get medium sized rain drops, we get 356 00:20:14,960 --> 00:20:19,080 Speaker 3: real heavy rain drops, and I keep thinking that a 357 00:20:19,119 --> 00:20:22,280 Speaker 3: good injector is that first one that missed that fine 358 00:20:22,280 --> 00:20:26,199 Speaker 3: atomization that you know, So just because just dumping fuel 359 00:20:26,280 --> 00:20:29,960 Speaker 3: into the cylinder in a glob isn't isn't going to 360 00:20:30,040 --> 00:20:33,080 Speaker 3: achieve correct combustion, and it's going to affect the engine 361 00:20:33,080 --> 00:20:37,359 Speaker 3: in so many ways. So when you look inside it, 362 00:20:37,440 --> 00:20:39,639 Speaker 3: and injectors have come such a long way since nineteen 363 00:20:39,680 --> 00:20:43,000 Speaker 3: eighty seven eighty eight, right when this became across the board. 364 00:20:43,600 --> 00:20:45,840 Speaker 3: You know, when you look at a modern fuel injector 365 00:20:45,880 --> 00:20:47,679 Speaker 3: and I don't know, maybe we compare it to stuff 366 00:20:47,680 --> 00:20:51,800 Speaker 3: from thirty five forty years ago, you know, what's what's 367 00:20:51,880 --> 00:20:54,520 Speaker 3: that important part that makes everything work correctly? What are 368 00:20:54,520 --> 00:20:57,000 Speaker 3: we looking for when we consider replacement. 369 00:20:58,160 --> 00:21:00,879 Speaker 5: Yeah, so there's a lot of little pe inside of 370 00:21:00,920 --> 00:21:05,080 Speaker 5: an injector. Right, There's a calibration pin spring, a small 371 00:21:05,240 --> 00:21:07,919 Speaker 5: armature assembly with a ball bearing on the top of it, 372 00:21:08,480 --> 00:21:10,600 Speaker 5: a valve seat, and all of that is involved with 373 00:21:10,960 --> 00:21:14,919 Speaker 5: metering the fuel, you know very quickly. But hands down, 374 00:21:15,480 --> 00:21:20,280 Speaker 5: the very very most important components on or in that 375 00:21:20,359 --> 00:21:23,840 Speaker 5: injector is at the tip, and that's the metering disc. 376 00:21:24,960 --> 00:21:28,639 Speaker 5: It's a really small disc. It's about five and a 377 00:21:28,680 --> 00:21:33,639 Speaker 5: half millimeters across, and these are going to have holes 378 00:21:33,880 --> 00:21:37,560 Speaker 5: that are drilled into them. We use blazers to drill 379 00:21:37,600 --> 00:21:41,720 Speaker 5: the holes onto the disc. And how the pattern that 380 00:21:41,720 --> 00:21:44,080 Speaker 5: those holes are in, the size of the holes, the 381 00:21:44,119 --> 00:21:48,960 Speaker 5: angle they are cut are all application specific, right, and 382 00:21:49,000 --> 00:21:51,800 Speaker 5: the holes are small. Right. We measure these things in microns. 383 00:21:51,880 --> 00:21:54,520 Speaker 5: I mean they can be much, not much bigger than 384 00:21:54,520 --> 00:21:57,639 Speaker 5: a human hair. You know, some applications are going to 385 00:21:57,720 --> 00:22:00,760 Speaker 5: have four, some are six, summer eight, some are patterns. 386 00:22:01,280 --> 00:22:05,400 Speaker 5: But that is really the most important part of an injector, 387 00:22:05,440 --> 00:22:08,960 Speaker 5: and that's what's the most critical part to getting that 388 00:22:09,200 --> 00:22:12,840 Speaker 5: right spray angle and that right spray pattern for that 389 00:22:12,880 --> 00:22:13,920 Speaker 5: particular engine. 390 00:22:13,920 --> 00:22:16,720 Speaker 3: How thick is that I'll call it a wafer. I 391 00:22:16,760 --> 00:22:18,840 Speaker 3: don't know if wafer is a good term, or that disc. 392 00:22:18,920 --> 00:22:22,200 Speaker 3: How thick is that disc? It's it's thin, it's it's. 393 00:22:22,119 --> 00:22:24,440 Speaker 5: It's thin, I mean, it's it's yeah, it's just it's 394 00:22:24,480 --> 00:22:26,919 Speaker 5: thinner than a dime, right, And it's and then it's 395 00:22:27,000 --> 00:22:29,119 Speaker 5: it's it's just it's laser welded on to the end 396 00:22:29,200 --> 00:22:31,720 Speaker 5: of the tip of the injector, right, And and I. 397 00:22:31,680 --> 00:22:35,240 Speaker 3: Guess we could say that that that that wafer, that 398 00:22:35,400 --> 00:22:39,320 Speaker 3: disc is what makes fuel delivery today so precise, right. 399 00:22:40,040 --> 00:22:43,199 Speaker 5: Absolutely, yeah, yeah, And it's why it just has to 400 00:22:43,200 --> 00:22:44,760 Speaker 5: be it has to be perfect. 401 00:22:45,160 --> 00:22:47,480 Speaker 3: Well, it does well, but isn't that you know, And 402 00:22:47,560 --> 00:22:52,160 Speaker 3: to talk about standard in particular, right, Standard makes sure 403 00:22:52,240 --> 00:22:56,640 Speaker 3: fuel injector spray accurately and consistently because that's it too, right, 404 00:22:56,960 --> 00:22:59,800 Speaker 3: you have to have that misting april rain all the time. 405 00:23:00,400 --> 00:23:02,080 Speaker 3: And a lot of that has to do with how 406 00:23:02,119 --> 00:23:04,879 Speaker 3: you I think you've created that technology and how you 407 00:23:04,920 --> 00:23:07,200 Speaker 3: cut that disc and use a laser for the precision, 408 00:23:07,240 --> 00:23:09,520 Speaker 3: and you know you're not drilling the whole your you're 409 00:23:09,640 --> 00:23:10,840 Speaker 3: laser cutting that hole. 410 00:23:12,080 --> 00:23:14,920 Speaker 5: Yeah yeah, I mean it really is the best way 411 00:23:15,000 --> 00:23:18,880 Speaker 5: to make them consistent, you know, across the board when 412 00:23:18,920 --> 00:23:21,320 Speaker 5: you're producing you know, thousands of these at a time. 413 00:23:22,080 --> 00:23:24,159 Speaker 5: And I think the other difference too is you know, 414 00:23:24,240 --> 00:23:27,120 Speaker 5: we won't use a batch metering disc. We will use 415 00:23:27,359 --> 00:23:31,040 Speaker 5: application specific ones, you know. So at our factory and 416 00:23:31,160 --> 00:23:34,880 Speaker 5: you know in Greenville, South Carolina, where we make fuel injectors, 417 00:23:35,040 --> 00:23:38,280 Speaker 5: you know, we have you know, hundreds of different metering 418 00:23:38,320 --> 00:23:42,480 Speaker 5: discs that we create depending on you know, what it's 419 00:23:42,480 --> 00:23:44,000 Speaker 5: going on, what. 420 00:23:44,160 --> 00:23:46,320 Speaker 3: Vehicle specific application. 421 00:23:46,040 --> 00:23:49,119 Speaker 5: Right, yeah, yeah, And that's that's all part of it. 422 00:23:49,160 --> 00:23:51,439 Speaker 5: And then you know, in that plant, you know, we're 423 00:23:51,520 --> 00:23:55,359 Speaker 5: able to control the whole process from start to finish, right, 424 00:23:55,400 --> 00:23:57,720 Speaker 5: I mean, we're we're cutting our own rods, we're doing 425 00:23:57,720 --> 00:24:00,600 Speaker 5: our own heat treating, we're doing our own overbolding. Uh, 426 00:24:00,880 --> 00:24:03,320 Speaker 5: so we you know, we can build a quality part 427 00:24:03,400 --> 00:24:05,640 Speaker 5: because we're controlling the process. 428 00:24:05,960 --> 00:24:08,840 Speaker 3: So when we look at and there's different kinds of 429 00:24:08,840 --> 00:24:13,399 Speaker 3: fuel injection, there's GDI, there's multiport injection. Some vehicles have 430 00:24:13,520 --> 00:24:17,639 Speaker 3: GDI and multiport right late model Toyotas for example, And 431 00:24:18,600 --> 00:24:22,040 Speaker 3: you know, when you look at those two systems, first 432 00:24:22,119 --> 00:24:24,920 Speaker 3: my first question is what's the what's the real difference 433 00:24:24,920 --> 00:24:28,080 Speaker 3: and what are the concerns the consumer has right to 434 00:24:28,440 --> 00:24:30,159 Speaker 3: know the difference. What are some of the things they 435 00:24:30,200 --> 00:24:32,840 Speaker 3: have to be aware of? And then number one number two, 436 00:24:33,320 --> 00:24:37,560 Speaker 3: you know, do you manufacture a GDI injector different than 437 00:24:37,600 --> 00:24:40,600 Speaker 3: you do a multiport injector? Does that affect how you 438 00:24:40,640 --> 00:24:42,320 Speaker 3: cut that disc and spray the fuel? 439 00:24:43,280 --> 00:24:47,359 Speaker 5: Yes? Yeah, the short story is yes. And GDI injection 440 00:24:47,840 --> 00:24:52,679 Speaker 5: is different, right than m FI. So MFI, you know, 441 00:24:52,760 --> 00:24:57,359 Speaker 5: it became common geez thirty years ago, right, and it 442 00:24:57,480 --> 00:25:01,320 Speaker 5: was on most vehicles up to maybe fifteen years ago, 443 00:25:02,119 --> 00:25:06,240 Speaker 5: and we started seeing more and more GDI, And with 444 00:25:06,359 --> 00:25:10,879 Speaker 5: GDI it's just such a constant pressure all of the time, 445 00:25:11,200 --> 00:25:15,000 Speaker 5: and I think, you know, yeah, the injectors are different fundamentally. 446 00:25:15,040 --> 00:25:18,560 Speaker 5: Probably the easiest way to explain it is, you know, 447 00:25:18,600 --> 00:25:22,959 Speaker 5: with an MFI injector, it's spraying the fuel above the 448 00:25:23,000 --> 00:25:27,160 Speaker 5: intake valve. And you know with direct injection, I mean 449 00:25:27,200 --> 00:25:31,640 Speaker 5: it's exactly that, right, the fuels being sprayed directly into 450 00:25:31,640 --> 00:25:37,879 Speaker 5: the cylinder, so below the intake valve. But there's some 451 00:25:37,880 --> 00:25:41,080 Speaker 5: some there's been some issues with GDI, right, I mean, 452 00:25:41,240 --> 00:25:42,879 Speaker 5: you know, you get a lot of carbon build up 453 00:25:42,880 --> 00:25:45,960 Speaker 5: on the valves, even you can get carbon build up 454 00:25:45,960 --> 00:25:49,679 Speaker 5: on the injector tip. But it also opens up a 455 00:25:49,720 --> 00:25:53,400 Speaker 5: couple you know, new areas of failure points, right, because 456 00:25:53,440 --> 00:25:56,440 Speaker 5: now you have two fuel pumps. You know, you have 457 00:25:56,480 --> 00:25:59,600 Speaker 5: a high pressure pump that's you know, feeding fuel a 458 00:26:00,080 --> 00:26:02,880 Speaker 5: really high pressure to the fuel rail, and you have 459 00:26:03,040 --> 00:26:07,840 Speaker 5: more fuel pressure sensors. So you know, it's there's more 460 00:26:07,840 --> 00:26:10,639 Speaker 5: things to go wrong on a GDI system as well, right, 461 00:26:10,720 --> 00:26:14,240 Speaker 5: And you're exactly right, Ford Toyota. You know, more and 462 00:26:14,280 --> 00:26:16,760 Speaker 5: more they're using both on these vehicles. 463 00:26:16,600 --> 00:26:20,680 Speaker 3: And they're doing it, you know, for precision because the GDI. 464 00:26:21,200 --> 00:26:24,280 Speaker 3: GDI actually allows us in case anybody to know this, 465 00:26:24,400 --> 00:26:27,920 Speaker 3: but it gives us stability to you know, it used 466 00:26:27,920 --> 00:26:30,600 Speaker 3: to be you'd fire the injector so many degrees before 467 00:26:30,640 --> 00:26:33,280 Speaker 3: top that center. You know, each cylinder three degrees before 468 00:26:33,359 --> 00:26:36,560 Speaker 3: four degrees before GDI. Lets you do it it, lets 469 00:26:36,560 --> 00:26:40,639 Speaker 3: you vary it by the cylinder, by the by the demand, 470 00:26:40,760 --> 00:26:44,280 Speaker 3: by the condition, and that so that injector is working 471 00:26:44,680 --> 00:26:49,160 Speaker 3: really hard to meet a very precise condition, which brings 472 00:26:49,200 --> 00:26:52,159 Speaker 3: me back to my original question that you answered with 473 00:26:52,240 --> 00:26:55,160 Speaker 3: regard to the disc. Right, that disc has to be 474 00:26:55,600 --> 00:26:58,880 Speaker 3: just perfect in order for it to do its job 475 00:26:58,920 --> 00:27:00,720 Speaker 3: and let the vehicle run as good as it can 476 00:27:01,000 --> 00:27:03,560 Speaker 3: and get the fuel economy which is obviously so important 477 00:27:03,600 --> 00:27:05,440 Speaker 3: today in this day and especially with the price of 478 00:27:05,480 --> 00:27:06,280 Speaker 3: gasoline today. 479 00:27:06,840 --> 00:27:08,080 Speaker 5: Oh yeah, you aren't kidding. 480 00:27:08,320 --> 00:27:10,040 Speaker 3: Yeah, So I'll tell you what, Aaron. Let's pull over, 481 00:27:10,080 --> 00:27:12,280 Speaker 3: take a pause, and when we come back, I want 482 00:27:12,280 --> 00:27:14,080 Speaker 3: to talk a little bit about what goes bad on 483 00:27:14,119 --> 00:27:17,120 Speaker 3: an injector. And you know, when they do go bad, 484 00:27:17,160 --> 00:27:19,199 Speaker 3: do we replace one, do we replace four? Do we 485 00:27:19,240 --> 00:27:20,840 Speaker 3: replace eight? You know, how does that work? And what 486 00:27:20,880 --> 00:27:22,720 Speaker 3: are your thoughts on that. I'm running any in the 487 00:27:22,720 --> 00:27:26,119 Speaker 3: car doctor, I'm here with Aaron Schaeffer from Standard Motor Products. 488 00:27:26,160 --> 00:27:27,159 Speaker 3: We'll return right after this. 489 00:27:27,200 --> 00:27:43,000 Speaker 2: Don't go away so. 490 00:27:43,040 --> 00:27:45,600 Speaker 3: To continue with our conversation. Welcome back listeners. By the way, 491 00:27:45,680 --> 00:27:47,800 Speaker 3: roun An Annie in the car doctor here with Aaron 492 00:27:47,800 --> 00:27:50,880 Speaker 3: Schaeffer from Standard Motor Products. Aaron, when we pulled away 493 00:27:50,880 --> 00:27:53,159 Speaker 3: for the pause. You know what goes bad on a 494 00:27:53,160 --> 00:27:56,560 Speaker 3: fuel injector and when it does go bad, do I 495 00:27:56,600 --> 00:27:58,919 Speaker 3: need to change one? Do I need to change ford? 496 00:27:58,960 --> 00:28:01,080 Speaker 3: Do I need to change you know? 497 00:28:01,119 --> 00:28:01,920 Speaker 2: How many? And why? 498 00:28:03,000 --> 00:28:05,879 Speaker 5: Yeah? So there's a couple of root causes, right. Some 499 00:28:06,040 --> 00:28:09,720 Speaker 5: could be electrical issues, right, a lot of heat cycles, vibration, 500 00:28:10,000 --> 00:28:12,480 Speaker 5: they have a coil inside, so that could be part 501 00:28:12,520 --> 00:28:18,240 Speaker 5: of it. Debris, dirt, contaminated fuel you know, starts to 502 00:28:18,400 --> 00:28:21,399 Speaker 5: you know, gum up the injector a little bit. They 503 00:28:21,400 --> 00:28:25,200 Speaker 5: could leak, you know, seals can fail. Carbon build up, 504 00:28:25,440 --> 00:28:28,919 Speaker 5: as I said earlier, is something very very common on 505 00:28:29,160 --> 00:28:33,560 Speaker 5: GDI injectors. So to answer your question, should you replace 506 00:28:33,840 --> 00:28:39,600 Speaker 5: all four all eight at once? Generally speaking? Yes? But 507 00:28:40,360 --> 00:28:44,560 Speaker 5: here's why. It's because I think most people understand this 508 00:28:44,640 --> 00:28:48,840 Speaker 5: once we explain it. The ECU has no way of 509 00:28:49,040 --> 00:28:52,920 Speaker 5: knowing how good an individual injector is working. If it's 510 00:28:53,080 --> 00:28:55,240 Speaker 5: you know, if it's working at one hundred percent, or 511 00:28:55,320 --> 00:28:58,120 Speaker 5: if the spray pattern is off by five percent, or 512 00:28:58,120 --> 00:29:00,320 Speaker 5: if it's flowing at six percent less, or if it's 513 00:29:00,320 --> 00:29:04,480 Speaker 5: flowing at twenty percent less, the ECUs only getting data 514 00:29:04,640 --> 00:29:08,240 Speaker 5: on the entire bank. Right, There isn't a vehicle. There 515 00:29:08,280 --> 00:29:11,920 Speaker 5: aren't vehicles out there that have O two sensors preach 516 00:29:12,000 --> 00:29:15,200 Speaker 5: cylinder every yeah, yeah, right, that's not that's not how 517 00:29:15,200 --> 00:29:19,120 Speaker 5: it works. So, yes, right, the vehicle can tell pretty 518 00:29:19,160 --> 00:29:22,200 Speaker 5: quickly if there's a lean condition or a rich condition, right, 519 00:29:22,240 --> 00:29:26,240 Speaker 5: and it's going to make adjustments. But if you can 520 00:29:26,360 --> 00:29:30,920 Speaker 5: have one injector that's gummed up, clogged up, metering disc 521 00:29:30,960 --> 00:29:34,560 Speaker 5: is starting to get plugged, it's so it's flowing less 522 00:29:34,560 --> 00:29:38,760 Speaker 5: fuel the injector next to it, you know, you could 523 00:29:38,800 --> 00:29:40,960 Speaker 5: be it could be failed. You could you know, you 524 00:29:40,960 --> 00:29:43,000 Speaker 5: could something could be stuck inside. It could be dripping 525 00:29:43,080 --> 00:29:46,960 Speaker 5: straight fuel down, right, So you just don't know how 526 00:29:47,040 --> 00:29:51,480 Speaker 5: individual injectors are performing. So if one has failed, you know, 527 00:29:51,560 --> 00:29:55,440 Speaker 5: especially if we're talking higher mileage vehicle, you know, certainly 528 00:29:55,520 --> 00:29:58,080 Speaker 5: the other vehicles or the other injectors are not flowing 529 00:29:58,120 --> 00:29:59,920 Speaker 5: at one hundred percent, right, right. 530 00:30:00,120 --> 00:30:01,960 Speaker 3: And I guess it's I guess it's a safe assumption 531 00:30:02,040 --> 00:30:05,280 Speaker 3: if if one injector got gummed up to the point 532 00:30:05,280 --> 00:30:10,680 Speaker 3: that it was pushing out droplets instead of atomization, then 533 00:30:10,720 --> 00:30:12,880 Speaker 3: you've got to think, you know, it's the same gas 534 00:30:13,560 --> 00:30:17,680 Speaker 3: in the tank exactly right, right, So the rest of 535 00:30:17,720 --> 00:30:20,600 Speaker 3: them have to be affected by that to some degree. 536 00:30:21,240 --> 00:30:23,880 Speaker 5: And you could put a new one on and you 537 00:30:23,840 --> 00:30:26,600 Speaker 5: you're still might not restore fuel economy to the way 538 00:30:26,760 --> 00:30:30,280 Speaker 5: the vehicle's capable of, because again the ECU is not 539 00:30:30,280 --> 00:30:33,760 Speaker 5: getting good information because the other ejectors aren't working as 540 00:30:33,840 --> 00:30:34,880 Speaker 5: de signe, is. 541 00:30:34,840 --> 00:30:37,080 Speaker 3: There a in our closing minute and a half Erran, 542 00:30:37,240 --> 00:30:40,160 Speaker 3: is there is there a life expected life cycle of 543 00:30:40,200 --> 00:30:41,440 Speaker 3: a modern fuel injector. 544 00:30:43,320 --> 00:30:48,040 Speaker 5: You know, if it's taken care of, well, I mean 545 00:30:48,160 --> 00:30:50,480 Speaker 5: they can go we you know, we've seen them go 546 00:30:50,680 --> 00:30:53,360 Speaker 5: one hundred two hundred thousand miles right if people are 547 00:30:53,440 --> 00:30:57,520 Speaker 5: using you know, you know, the right fuel, keeping them clean, 548 00:30:57,640 --> 00:30:59,440 Speaker 5: you know, not running the tank low. I mean it 549 00:30:59,440 --> 00:31:02,320 Speaker 5: can it can definitely happen, right, And and I. 550 00:31:02,320 --> 00:31:04,480 Speaker 3: Guess that's that's all part of it, right, that that 551 00:31:04,560 --> 00:31:06,960 Speaker 3: it's that it's you know that it's not it's not 552 00:31:07,040 --> 00:31:10,360 Speaker 3: it's good quality fuel. It's consistency of fuel. It's not 553 00:31:10,480 --> 00:31:13,920 Speaker 3: running the tank low, which you know, which which affects 554 00:31:13,960 --> 00:31:16,840 Speaker 3: the injector life and tends to pick up the crud 555 00:31:16,840 --> 00:31:19,959 Speaker 3: and the dirt from the bottom Aaron in our closing minute, 556 00:31:20,000 --> 00:31:21,960 Speaker 3: is there a place the listeners can go for more 557 00:31:21,960 --> 00:31:24,720 Speaker 3: information and is there a way to get Standard product, 558 00:31:25,040 --> 00:31:26,560 Speaker 3: you know online if they want to look it up 559 00:31:26,560 --> 00:31:27,160 Speaker 3: and purchase it. 560 00:31:28,480 --> 00:31:32,120 Speaker 5: Yeah.

Once again, I want to 590 00:32:52,760 --> 00:32:55,360 Speaker 3: say thank you to Aaron Schaffer from Standard Motor Products 591 00:32:55,560 --> 00:32:58,800 Speaker 3: for taking the time today. There's a lot too fuel 592 00:32:58,800 --> 00:33:00,960 Speaker 3: injectors that we know, a lot we can't cover in 593 00:33:01,000 --> 00:33:05,280 Speaker 3: a twenty minute interview, but I think your takeaway from 594 00:33:05,440 --> 00:33:10,840 Speaker 3: our conversation today is the precision and the skill set 595 00:33:10,880 --> 00:33:12,800 Speaker 3: and quality of what it takes to make a good 596 00:33:12,800 --> 00:33:16,080 Speaker 3: fuel injector. You know, you'd have to see the facility. 597 00:33:16,080 --> 00:33:20,840 Speaker 3: I've toured fuel injection manufacturing facilities in the past, and 598 00:33:21,000 --> 00:33:23,239 Speaker 3: there there are clean rooms, and it has to be 599 00:33:23,280 --> 00:33:27,840 Speaker 3: precise and it has to be you know, absolutely correct 600 00:33:27,960 --> 00:33:30,360 Speaker 3: in the way that they make the holes in the 601 00:33:30,440 --> 00:33:34,320 Speaker 3: disc that distributes the fuel, which Aaron had talked about. 602 00:33:34,360 --> 00:33:36,760 Speaker 3: You know, those those those metering plates as I think 603 00:33:36,800 --> 00:33:39,480 Speaker 3: of it, because they are they've they've got to be 604 00:33:39,520 --> 00:33:44,480 Speaker 3: spot on. And you'll be amazed how we've seen cases 605 00:33:44,640 --> 00:33:49,160 Speaker 3: where using two injectors from two different manufacturers, if that 606 00:33:49,240 --> 00:33:54,080 Speaker 3: second manufacturer isn't a well made injector, it will actually 607 00:33:54,080 --> 00:33:56,600 Speaker 3: cause problems because it won't spray fuel as well, or 608 00:33:56,680 --> 00:34:00,920 Speaker 3: even an older injector that has partial restriction to it. 609 00:34:01,440 --> 00:34:03,520 Speaker 3: And it's gotten to the point that when we do 610 00:34:03,560 --> 00:34:07,120 Speaker 3: fuel injector work, putting injectors into a flow bench which 611 00:34:07,160 --> 00:34:10,600 Speaker 3: actually measures the volume of fuel being put out by 612 00:34:10,640 --> 00:34:13,239 Speaker 3: the injector, so you can look at spray pattern and 613 00:34:13,320 --> 00:34:15,640 Speaker 3: you can look at volume of fuel being put out 614 00:34:16,360 --> 00:34:19,839 Speaker 3: over a time span, can tell the tale on some 615 00:34:19,960 --> 00:34:22,480 Speaker 3: cars that are just really difficult to diagnose and repair. 616 00:34:22,560 --> 00:34:24,640 Speaker 3: So there's a lot that can't be covered, but I 617 00:34:24,680 --> 00:34:26,200 Speaker 3: think we covered quite a bit and I'm glad that 618 00:34:26,200 --> 00:34:28,120 Speaker 3: we were able to get that information out to you. 619 00:34:28,120 --> 00:34:30,520 Speaker 3: And Aaron did a great job as always, and we'll 620 00:34:30,560 --> 00:34:32,279 Speaker 3: have him back again real soon we can talk some 621 00:34:32,320 --> 00:34:37,440 Speaker 3: more about Standard products and again his website Standard brands 622 00:34:37,480 --> 00:34:39,920 Speaker 3: dot Com I'll say it one more time.
