I Could Use Some Insight On A 6.6 Duramax Diesel Utility Service Van


I have been looking for for a used utility service body van for months now and they seem to be in short supply.

I finally found on that meets my criteria but it has a 6.6 Duramax Diesel with 150k miles on it. The van is an 06 Chevy with a 11' Stahl enclosed body. I have never owned a diesel vehicle and know nothing about the longevity or reliability of the motor. I am also leery of buying something with 150k but from what I have heard that is nothing for a diesel.

I guess my question would be what kind of life can I expect out of that engine with 150k on it and are there any problems I should worry about. The van itself is really nice and looks very well taken care of.

Any help or advice would be greatly appreciated.

Thanks

I've never kept one past 100k but I hear they last and any problems are in the early life of the motor. Knock on wood I've never experienced a duramax problem and have owned 4 of them so far.

As for a diesel motor...the girls at the drive thru coffee shops like the duramax motors too, very quiet compared to others and no need to turn it off when ordering

Thanks Chris. Any input on what the fuel mileage is with one of those?

Not sure with the utility box, I can get almost 23 mpg just running the highway, but I'm usually an empty truck. If I'm in the city it's around 16 mpg. I've been checking it lately with spread out projects and I'm averaging a little over 18 mpg.

It's not gonna be the motor it will be all the other parts that go and nickel and dime you to death

On the new dirty max on a pick up motor trend said 14 mpg loaded or not

My van has a 120 thou on it and all I have replaced were brakes and rotors wheel bearing assemblies and a u joint and a tierod from running off road tires it's awd is the reason for the tires but now I run street tires it goes anywhere you want it's a beast

Good luck

Yeah i guess with 150k there might be a bunch of little things. The fuel mileage sounds good to me though.

I really don't want to sink a bunch of money into the vehicle, but I also understand that a vehicle of that mileage might have some repairs to be made.

It seemed to have been taken care of but looks can be deceiving.

i have an 06 3500 express van with durmamax that i bought new. i dont have a lot of miles on it (60k) but overall its been reliable. i once had to get a new egr valve installed because the original was sticking. covered under warranty. i also installed a 4" exhaust and bully dog tuner. the van flies now. i have a heavy foot, and no problems yet. i'd get around 16 mpg mostly around town, and about 20 on the highway....with my van usually loaded with tools. i would never go gas again. the power and mpg of a diesel is worth it.

I know of 6 D-maxs that all get 20+ mpg even the 4x4s so I think motor trend if full o crap as usual

The cost of ownership is less with the GM then ford or dodge. and less downtime

The 05 that pulls the 34ft enclosed race trailer has 270k on it and has only needed tires and brakes. averages 24 empty and 19 with trailer pulling hills and mountains at 75 mph

the 08 4x4 is heavily modded and will smoke a 1/4 mile in 12 sec yet still get 20 mpg with 33 inch mudgrip tires


Ford circled the problem in the emblem and Dodge is what you do when you see a mopar for sale hehehe

Most of the people I know with the Isuzu diesel motor with aluminum heads found in GM vans and pick ups don't get the steller mileage you hear reported on forums. Most often first hand real world (not by a computer) is 16-19 mpg.

The newer the diesel motor in most cases the lower the fuel mileage. If you go on PSD, Cummins (I6 diesel motor like most semi's), and Isuzu/GM forums you'll see a lot of posts from members who complain they don't get the mileage with their new diesel like they did with their old diesels.

Some guys remove some of the emission equipment voiding the warranty but in return increase their fuel mileage. If you live in a state that does inspections DON'T DO IT!!!

To answer the OP's question, IMO? Although 150K miles may seem like a lot it's really not that many miles for a diesel.

My three diesels currently have 226K, 236K, and 311K miles. I'd drive any of them any were and not think twice about it.

Hearing about your vehicles with over 200k and still running strong eases my mind a bit.

If it made it to 250k with no major problems i would be satisfied. Of course i would love more but I would be alright with getting 100k out of it.

If I get it I will have to look into the mods for better mileage but I would settle for the 15-16 mpg and be happy with that too.

Re: I Could Use Some Insight On A 6.6 Duramax Diesel Utility Service Van


You should have few problems with the van although IMO i would not tune it. The vans do not have the Allison tranny and the engine has been detuned so the 4L80E will survive behind it. Even after a good rebuild these trannies wont survive long with a tuned engine. Other than the typical EGR problems you will have a great van. All diesels come with the G-80 in the rear too, that van will be a tank in the snow.

Re: I Could Use Some Insight On A 6.6 Duramax Diesel Utility Service Van


I talked with a couple guys that have the above trucks and they figure the milage by mi/gallons on a calculator

One did say is 06 averaged 19 when he got it, but after putting on an AFE cold air and better muffler it was 21, then came the EDGE programer and 23 to 25mpg on stage 2

Other said his 07 was 19 then he got slightly taller tires and its 23, only mod is a K&N filter


Like gasoline diesel fuel has different additives depending on what station its at and the differences can be 1-2 mpg, large metros also mandate more crap be added to reduce (nox or whatever it is) thats why everyone here says buy fuel before getting to say Albequrque or OK City
