well there is a local guy who bought his 2001 duramax used from our dealership in november 2003 when it had 87,000 miles. he started hauling trailers nationwide with the truck and just brought it in on saturday march 4 with 307,000 miles on the odometer. he has routinely brought it in for oil changes and major repairs when he is in the area, which i have done all work to this truck. i am a little impressed, but more disgusted u could say for that we got talking bout the truck and whatnot, and since he purchased it, he has sank almost 20,000 dollars into this truck in repairs only just to get it to a measley 300,000 miles. this truck has had two sets of injectors, two sets of injector sleeves, now needs another set of injectors (sleeves likely to pull out again due to carbon buildup), two high pressure fuel pumps, two allisons (both of which had routine flushes and filter changes), one fuel injection control module, one PCM, and the list goes on and on with little stuff. impressed that this v-8 made it this far without cracking a piston, or a head, or both like a 6.5 would. and without losing all compression like a 6.5 and needing ether assist even in the middle of july, but that is alot of money to throw at repairs. now he tows only singles, bumper pull, being a max length of 24 ft. so not much of a load. this truck burns oil pretty good, so it is pretty much on its last leg. my brothers 96' 12 valve like mine has 250,000 miles and is strong as ever, burns no oil, and still has original injectors and injection pump. just more proof that 6 is better than 8.
"why have 8 when you can just have it straight!"

 

307K miles?

well that is super respectable for a duramax. Considerin it is a newer engine this has proven that is is better than a 6.0. highest number mileage i have heard from a 6.0 is about 85K...

There was a guy a couple of years ago who went by the handle of Brokers. He runs fleets of car haulers and boats between Canada and Florida. His first Dmax went to 547K with one set of injectors two trannys and about five alternators. There might have been a rear end too. He runs Fords Dodges and Dmaxes and usually keeps all to well over 400K before he sold them. His first 6.0l Ford went over 400K also! He claims the Chevy's cost him less in repairs and maintenance than the other two. Many many people thought he was full of dooky about his mileage but I do believe he finally offered up some proof.

 

I read a post elsewhere by a guy that had put nearly 5k on his 6.0, problem free!

 

I'll give him 11 more miles before he's back at the dealer.

 

i talked to a guy that came into work a few months back. Had a 04 6.0 PSD with 47,000 miles on it. Im pretty sure he pulled smaller equipment with it b.c i had seen him in there with the trailer on it before and a front end loader. I asked him how he liked the truck (i had my 02 F250 7.3L at the time). He said that he had 47,000 miles on it and it was on its third engine. He said he was just waiting for this one to go so he could get it lemon lawed and get another truck. Not sure if he was telling everything accurately or not...but i find it commical anyways...seemed serious to me.

 

This guy is just a figment of his own imagination. All BS. None of his numbers are true, nor even close to being true. If in fact it was true you'd never see a class 7 or 8 on the road. Everybody'd be running f350's, getting 15mpg, no sleepers on them, and putting 250k a year on. Remember everything you read on the internet is true.....
Any fleet manager knows that a class 7or 8 costs less to run per mile for its life over a F350.

 

Like I said he did offer up some proof a while back and silenced a whole lot of folks who thought he was full of it. Why would he run class 7 trucks anyway? They cost twice as much to purchase new, get 60-70% of the mileage and for someone who is grossing under 25K as he is they are overkill.
Why would a fleet manager buy a truck that costs 55K, gets 7-10mpg and only use it to haul 15K when he can buy a 3500HD or F550 for about 35K (fleet prices) and get 10-13mpg? Seems to me that the small truck is more economical. Sure the small truck is going to break more stuff but relatively speaking it will be cheap stuff compared to a class 7.

 

i had an 04 6.0 and went through 2 engines in 52k, 3 injectors, 1 turbo, 2clutches and a bunch of time waiting. It seemed that the truck was i the shop more than on the road.

 

When I worked at an rv dealership. There was a guy who done nothing but deliver trailer houses nation wide. He showed me the odometer and it read over 900,000 miles. I asked him how many motors he had went through and he said none. Just reg. maint. He also said he had been through nine transmissions in those nine hundred thousand miles. Yes you guest what kind of truck it was. the allways reliable cummins.

 

Well , its nice to learn that I'm a figment of my own imagination. And yes we do have class 8's also.

 

The stroke and the isuzumax are diesels... I respect them more than the average ford or chebby. I think a diesel should get 300,000 miles... that's one reason why you get a diesel - at least that's why I got one.

My buddy works for GM warranty... He said the isuzumax is getting better. Most all the problems he's seen were electrical, particularly with the Allison. Its funny because the tranny is fine, it is GM's harness that is causing all of the problems.

Off the subject, but what I don't understand about the v8's is that they don't offer the benefits of a diesel. Its like a strange twilight zone thing: Diesel with no low end torque

Still better than a v10, but strange why anyone would want a diesel that behaves like a gas motor I think people are gimmicked by the numbers... who the heck wants their power at top RPM?

 

I'd suggest you go and talk to any fleet manager out there. Cost per mile/income per mile class 7 or 8 will always come out ahead.
Class 8's are a hell of a lot more than 55k.
I'm not going to argue about this guy. His numbers are bogus. You can't run the mileage and hours he says he does without sleepers. To buy 550's and stretch them for sleepers is not cost effective. To have a driver waiting by the interstate every 14 hours (hey that'd be convenient wouldn't it??) Not even going to mention 3500's or F350's: the resale of these 350's and 550's with 550k is nothing. Would you buy a 2 year old truck with half a million miles pulling 25k all its life?????? A class 8 with a million miles still sell for good money. So spend 40k for a truck that is toast in 550k or buy a 90k class 8 which hauls 10 cars instead of 3 (see where this is going??) that will last twice as long, makes more money per mile, less maintenance (it is built to pull). And if the car business craps out with a class 8 you can hook onto anyting with a pin. Car carriers last almost forever because they are not running max weights. Allied carriers has some GM Brigs still on the road. How old are those old goats?? They pulled cars their entire life.

 

Please if you would stay over on the Chebby boards where they seem to buy your dribble. Cummins owners are smart enough to see through your charades.

 

hmmm i can see where this is going... come on guys not on the boards
