00:00This video will teach you more about maintaining your diesel truck and not screwing it up and
00:06coming to see me for a motor than anything else I've ever put out there, I think.
00:16Good morning, everybody.
00:17I have got a really special treat.
00:19I get to look at a brand new truck with a good friend of mine, Glenn.
00:23We've known each other now for 15 years.
00:26About that, yeah.
00:27Went into the neighborhood, great neighbor, cornered me in church like people do about
00:32their vehicles and he said, hey man, I get in this new truck.
00:34He's got a lot of questions.
00:35He wants to maintain this truck because he follows me and he's a little nervous about
00:40not maintaining this thing right and he didn't want to come here for an engine in five years.
00:44I don't want to come back for that, no.
00:47What we're going to do today is we're going to try to educate him, is it first?
00:51I've never owned a truck nor have I ever had a diesel engine, so lots to learn.
00:55Yeah, because I'm assuming you're going to keep this thing.
00:57You don't want to trade this in in three years.
00:59You want to just drive the wheels off of it.
01:01Correct.
01:02As you can possibly get.
01:05Exactly.
01:06All right, let's go check this bad boy out.
01:07Oh, I like the color.
01:08Oh, it's good.
01:09Look at this.
01:10Brand new Glacier Gray, I think they said.
01:12Jesus, dude.
01:13New color for the year.
01:15Little man in a big truck, Dave.
01:17My friends were already teasing me.
01:18Well, who lifted it?
01:20Because this didn't come back.
01:21Ken Garf did something with it.
01:23Did they?
01:24I'm not sure who they sent it to.
01:25Wow.
01:26They didn't do it there though.
01:27They sent it out.
01:28Look at these wheels, dude.
01:29But you know, I'm going to Colorado all the time.
01:31I got to pull a big truck.
01:32Oh.
01:33Oh, Michelle, his wife has got to love this thing.
01:35I mean, come on.
01:37It even has a massage feature.
01:39You know, you push the button, it'll give you the massage.
01:41This is what you're getting, everybody.
01:43Yeah.
01:43You got to drop that coin, but man, you can get yourself a sweet truck.
01:47And that's the whole point.
01:48People ask me all the time, I'll just go ahead and cough it up right now.
01:51What's my favorite truck?
01:52It's a Ford chassis with a Cummins in it.
01:55Can't get the Cummins till you go up to a 750, which is a
01:58ridiculously big truck to drive, you know, just because you want one.
02:02But this is so sweet, man.
02:05Wow.
02:06Give me a question.
02:07Let's go look at the engine.
02:08I want to see the engine compartment.
02:09The biggest question I have is not having had a diesel, for example,
02:11I open up this and I see there's a blue thing for death.
02:14It's like, what the heck?
02:15The first thing I'm going to tell you about this is don't spill it.
02:19It is corrosive, you know?
02:21So you don't want to spill it anywhere.
02:23And if you do, rinse it off really good, quick.
02:25Is there a difference in quality?
02:26I've seen some of the filling stations have it, others don't and you have to buy it in
02:29a two and a half gallon container.
02:31Good question.
02:32I'm not a chemist.
02:33The honest answer to that is I have no clue.
02:35Okay.
02:36Just with respect to diesel, you know, obviously driving my cars, there's a difference in the
02:40fuel that you buy.
02:41Uh-huh.
02:42Is there a difference in the quality of diesel?
02:43And if so, I've been reading a lot about additives and things that you should add to that
02:47to get better octane performance, longevity.
02:49Okay.
02:50So these questions, it's like the pressure's on.
02:54Okay.
02:55The first question.
02:56Different qualities of fuel.
02:57Absolutely.
02:58And this is the first thing I'll say.
02:59Fuel is the enemy to your oil.
03:01You got to learn that right off the bat, especially with a diesel.
03:04Fuel is the enemy to your oil.
03:06And in a diesel, the fuel is being directed under high pressure, 30,000 PSI through an injector.
03:11Think of it like a sprinkler head in your yard, but at 30,000 PSI.
03:15And it's going somewhere, and where it goes is on the side of the cylinder wall.
03:20And then it washes down on the rings, and then some of it gets eventually into the oil.
03:25And that's why, I mean, it's the enemy to the oil.
03:28It degrades the lubricity and the cleanliness of the oil.
03:32Okay.
03:33Quality of your fuel is more important in a diesel than any other vehicle.
03:37I wanted to say something about this.
03:39Make sure you, you know, you never want to contaminate the diesel, you know.
03:42If you ever put gasoline in this truck, the best thing you'd ever do is don't cycle the
03:47key.
03:48Do not turn it on, because then all we have to do is drop the tank and flush it.
03:51You run gasoline through this system, this high pressure system, and you'll wipe it out.
03:56So do not contaminate your fuel source.
03:59You know, I do a lot of fishing, and I'm talking to captains, you know, and these boats, you
04:03know, got quarter of a million dollar diesel motors in them, and two of them.
04:06Yeah.
04:07Fuel polishers, and they call them fuel polishers, the filtration system.
04:12You know, they'll spend 50,000 bucks on a fuel polisher.
04:15Wow.
04:16So that their fuel going into those engines is pristine.
04:20Because they're getting that fuel at a dock in San Juan, Puerto Rico, you know, I mean,
04:25they're, you know, down in the Caribbean, down in Mexico, and so the quality of the fuel
04:29is always questionable.
04:30You know, obviously, when I fill up a car, I can see there's 87 octane or 89 octane, 91
04:35octane.
04:36Right.
04:37But diesels, I haven't seen that.
04:38No.
04:39All I've seen, I've only filled it up once, but it appears that there's just diesel.
04:41I did a video, and it was with Lake Speed Jr., and he is an oil, I mean, he is the guy,
04:49he helped formulated Joe Gibbs Racing Oil and all that other stuff.
04:53He goes to the refineries, and he knows that every refinery blends diesel totally different.
04:59Wow.
05:00They use different bases.
05:01Now, you know, again, I'm not the scientist on this.
05:04I just, you know, understand diesel fuel is different everywhere.
05:09Your fuel system is not only the thing that makes this thing run so well, but it's the
05:13thing that will take this thing down.
05:15Okay.
05:16One is for a system cleaner every 5,000 miles.
05:19That one is every time you fill up a couple ounces a gallon.
05:22Yeah.
05:23You know, if this was my diesel truck, like my tow truck, I do do fuel additives.
05:28I do.
05:29The hardest thing to keep on a diesel is the injector's pristinely clean.
05:34Okay.
05:35A diesel injector is like, just think of it as a sprinkler head in your yard.
05:39You know, what's an indication that the sprinkler head isn't like the pattern's not good anymore?
05:43You have brown spots of grass in places.
05:46You know, the water's coming out, but it's not squirting right there.
05:49And in a combustion chamber when that's happening is that's leaving unburned fuel because fuel,
05:54it needs to atomize.
05:55It needs to turn into a very fine particular mist.
05:59And if you've got like, it's doing that instead of like a vapor, it starts hitting the cylinder
06:06wall, washing down the cylinder wall, degrading your oil.
06:09And that causes incomplete combustion.
06:11I should add that to it.
06:12So when you don't have that atomization of fuel where it just turns into like a cloud,
06:17a mist, a fog, you lose power.
06:20Your fuel economy goes down and you start building a lot of soot.
06:24Okay.
06:25A lot of particulate.
06:26And that is basically unburnt fuel.
06:28You know, when you see these old diesel trucks, you know, going down the road, there's billowing
06:31black smoke.
06:32Yeah.
06:33And the boys love to do it.
06:34I say to boys, you know, I'd tell them, I'd say, you're just wasting fuel and you're ruining
06:38your engine.
06:39You know, if you really want to get the most horsepower or something, you want as much complete combustion
06:44as you possibly can get.
06:46And so when you have complete combustion, it means basically all the fuel is expended
06:51in the operation of that combustion.
06:52It's not wasted.
06:53And so you want to keep your fuel atomizing.
06:56The fuel atomized are the best way to do that.
06:59You're getting good fuel.
07:00I recommend that you would change your fuel filters every 15,000 miles.
07:04It is that important.
07:05I know some people go, that's a lot.
07:07I know this is a lot of talking to everybody, but it's a serious question, you know, because
07:11these trucks are a hundred, 120 grand, you know, all decked out.
07:15And the weakest point in them is the most expensive item in them.
07:19Yeah.
07:20And it's the engine.
07:21Now, when that fuel dust starts not to burn good, you get a lot of soot.
07:24And soot is unburnt fuel, that black smoke in a diesel.
07:28Well, in your diesel, they have a huge scrubbing system to clean the exhaust before it comes out
07:34of the tailpipe.
07:35And it is from the back of your motor to the exit of your car.
07:39That scrubbing system, which is a SCR, a DPF, a CAT, you know, all that stuff.
07:46I would guess that it, to replacement cost, is 10 grand.
07:49Wow.
07:50Yeah.
07:51And people steal them.
07:52Not in this area, but I mean, they'll cut it, you know, lay under a truck with a
07:56Sawzall and cut them off.
07:57Wow.
07:58And you'll go out one morning and all of a sudden your truck's real loud.
08:00How'd you look under it?
08:01It's gone.
08:02You know, that's another thing.
08:03It's very expensive because they have rare earth metals in those things.
08:05And that's how the catalyst reacts with the soot and everything.
08:09And then it burns off.
08:10That's what your DEF fluid is for.
08:12It injects that and it helps that reaction to happen in the exhaust stream.
08:16There is better ways to lower emissions, I believe.
08:19And some of them have been developed, like a Speed of Air Piston, that technology.
08:24But with this scrubbing system for your exhaust, what you want to do is you want to avoid
08:29overwhelming it.
08:31You get too much unburnt fuel in there.
08:33I mean, it's built to handle a minimum amount of that.
08:36But dirty injectors causes the black soot.
08:39The black soot then overwhelms the scrubbing system, this cleaning, exhaust cleaning system.
08:44And you also have, here comes the ugly thing that I do really hate on diesels, the EGR.
08:51It's an acronym.
08:52It means Exhaust Gas Recirculation.
08:55Am I got you asleep yet?
08:56Nope, not yet.
08:57This is the truth about stuff, so I'm hoping I'm explaining this well to everybody.
09:02Nox, nitrous oxides are the real problem.
09:05That's the real nasty pollution that causes burnt lungs and it's not good stuff.
09:10In order to reduce Nox, we circulate our exhaust gases.
09:15Everybody had to put EGR on diesel trucks.
09:18Okay.
09:19And that's where the diesel, you could see the longevity of a diesel motor went off a cliff.
09:26Now given this is a brand new vehicle, how long do you anticipate before I would ever have that kind of build up that it becomes a worry?
09:31And how would I know?
09:32It is so indicative of how you maintain the vehicle.
09:37And when I say maintain, it would be your oil changes, how long you idle it.
09:41Idling diesel for a long time with an exhaust gas recirculation on it, it kills them.
09:46They're not designed to just idle, you know, they're designed to work.
09:49Yeah.
09:50I recommend no more than 5,000 miles, but I would change oils full synthetic and a good filter every 3 to 3,500 miles.
09:56However, there is a better way to do that. Oil sampling.
10:01You have a driving style, most people do, that is pretty the same.
10:05You know, you get in your truck, you go to church, you go to work during the week.
10:09You know, you run into the grocery store, you haul in a boat up to the lake once or twice a month.
10:14You know, so your patterns are basically the same.
10:17Let's do an oil sample on your truck at 5,000 miles.
10:21Okay.
10:22Let's get a baseline and say, and we'll send it out for testing, it'll come back with all these results.
10:27And it'll say, you know, I've got sulfur buildup, subbuildup, or I don't.
10:31And we'll take a little oil sample, we'll send it in, it takes 48 hours.
10:35We'll get the results back and we'll say, your oil is as good as it was the day it went in.
10:40And I can know that.
10:41Yeah.
10:42And I say, we don't have to do an oil change.
10:43Your driving habits haven't changed that.
10:45Now, let's recheck it at 7, and then we'll check the degradation and stuff and make a determination of that.
10:51And then you can really understand how often you need to properly change your oil.
10:56It's easy to do, and it comes with a thing to draw oil out of the dipstick tube.
11:00I mean, it's really quite easy.
11:02They just need a test tube of it, a little plastic bottle.
11:05They send you a whole kit, you wrap it up, you send it back, you know, it's so easy.
11:09And we'll leave a link on the bottom of this for, Lake Speed's got a great company that does that.
11:14And he's so well known in the industry.
11:16I mean, he's such a great guy.
11:17You've got a lot of fluids in that car.
11:19You've got cooling system, you know, antifreeze.
11:21You've got hydraulic fluid in the power steering system.
11:24You've got hydraulic fluid in your transmission system.
11:27And you've got coolers that are cooling that off.
11:30So there's piping between all these units running to the front of the truck where the radiator is.
11:34You'll look in the front of that truck, and I mean, there's all these different coolers.
11:39They look like little radiators.
11:41And you're running fluid through that to cool it off.
11:43So you want to flush all that out.
11:45No more, if you're towing, no more than 30,000 miles.
11:48I just say that's the way to do it, you know.
11:50And 50,000 if you're just kind of like daily driving the thing, you know.
11:55You mentioned towing.
11:56Is there anything I should be careful of doing or not doing when I'm towing?
11:59Obviously, this thing's a beast.
12:01It's made to tow.
12:02Yeah.
12:03I've got some things.
12:04Do you have an EGR on the dash?
12:06Can you read the exhaust gas temperatures on that?
12:08I believe it does.
12:09It has diesel measurements.
12:10Yeah.
12:11This is what you should know as a new diesel owner.
12:12That you never want to get your exhaust gas temperatures over 1,350 degrees.
12:16Okay.
12:17For more than a minute.
12:19You know, you might be just coming over the top of parties, you know.
12:22And all of a sudden, it'll crest at 1,350 or something like that.
12:25You know, just back out of it a little bit.
12:27Instead of, you know, saying, I'm barreling over this thing at 85 because I can.
12:30Just back out of it a little bit.
12:32Okay.
12:33You'll see your EGT's, exhaust gas temperatures, decrease.
12:36Okay.
12:37That is the best insurance policy you can have that you'll never burn that thing down.
12:41Right.
12:42Now, you don't want to burn down diesel.
12:44I can show you.
12:45It'll burn a hole.
12:46It's like an acetylene torch, you know, like a blow torch.
12:48You burn a diesel down and it looks like you took a blow torch right to the side of the
12:51piston, burns right through the hole of the wall.
12:53Wow.
12:54Yeah.
12:55You know, I tell people all the time, it's on one of my t-shirts.
12:57It says, do your maintenance.
12:58Damn it.
12:59I'm busy.
13:00Good advice.
13:01Because if an engine builder is telling you how to not get your engine done, that's
13:07the guy you probably want to listen to.
13:09Yeah.
13:10Because I'm not doing all the changes here.
13:11That's why I came in this morning.
13:12I know.
13:13I know you'd set me straight and put me on the right track.
13:15You've always said you ought to have a good mechanic look at your vehicle at least once
13:19a year, once every 18 months and just, you know.
13:23If only I knew a good mechanic, Dave.
13:25I know.
13:26It's hard.
13:27It's hard to find, you know.
13:29It's hard.
13:30It's hard to find a good maintenance shop, you know, that can do that maintenance for
13:33you.
13:34Right.
13:35I'm confident that they do it properly.
13:37Gosh.
13:38Anything else?
13:39We covered a lot.
13:40We covered a lot.
13:41I'm sure there's going to be more as I start to get into it and drive it.
13:43Gosh.
13:44Even Thursday for a 500 mile trip and back, so.
13:47Cool.
13:48We'll get a chance to tow the trailer, see how it performs out on the way to Colorado.
13:52You know, I know this was boring, but this is probably one of the, I can't remember when
13:57I explained in detail how to take care of your diesel truck more than in this one.
14:01Glad to be the recipient of it, man.
14:02Thanks.
14:03Now, I know you just got done with the test drive of a McLaren, Dave.
14:06Yes.
14:07Brace yourself.
14:08Yes.
14:09Because this might top that.
14:10Yes, I know that.
14:11I know that.
14:12Sure is a nice truck, dude.
14:14It's really pretty in it.
