10K miles on her and hand calc is 22mpg highway/18mpg towing 30' toy hauler.

Break-in is 70-80K, so mileage will get better.



Let's all go trade our Cummins in...Right now!

 

Well, that is better than Ford's 6.4....

Come to think of it, I have been seeing more '08 Ford's on the used lot at County Line Ford here....

 

I bet that was down hill.
What does it do up hill and on level ground? HA HA!!!

 

That's better than any I've heard of even. Maybe he drives real nice but from what I've found they average more like 14. A buddy of mine with an 08 dually powerjoke gets 11.? All the new 08 emissions trucks are terrible. It sort of defeats the purpose of a diesel.

 

That is only 10 mpg better then what every other Duramax is getting

 

i had two rent 2 08 duramax's we put 18k on one and 12k on the other it never got better then 13 empty and towing we were lucky to get 10 with an empty trailer. they must be running down hill a lot with a 50 mph tailwind

 

Now I am NOT one to participate in any "Slam the other brand threads" as a rule, simply because I happen to believe there are good points to all of them.

BUT I wanted to pass along what happened to a friend this week. He purchased a new Duramax and with less than 1,000 miles on it, the tranny burned up on it.

I don't care what emblem is on the hood, that has to really hurt It can happen to any brand so please don't take this as a slam against the Chevy's, I just know how sick I would be if that happened to me.

Poor guy purchased it for his business and now it is in the shop and he is losing money daily because of it. I know lots of guys very happy with their Chevy trucks, I hope he can be as well one day.

 

My bet is he'll never be happy with it again after that fiasco.
It can run perfect from here on out but that'll still be in the back of his head.
That's how I'd feel anyway.

 

hey i'm not slamming any brand i have 07 ctd sitting at the house thats an 8800 pound paperweight till we go to court. i was just reporting the mileage i got out of them. those were very tough trucks i put them thru heck to see how tough they where. i had less problms then i did with my 07 in the same amount of time and miles

 

Let me know how they got that mileage, my brotherinlaw has an 08 and one of my buds has an 07 and there always edit at me because i get better mileage, empty and towing,

 

...X 2 !!!

 

I made that comment because I've been with guys like that. Any brand- ans ask them to show me the mileage figures.
Well, we go for a drive, they set the overhead to read instantaeous mpg.
Then slightly lift thee throttle . There it is a high number! Now this is not an average mpg.
I tell then to enjoy thier truck. If they like it, that is all that matters.

 

Yeah!! Hooked to the tow truck that hauling it to the dealer for some fresh injectors

 

A friend of mine has an 08 D-max and he is getting 21ish on the freeway and like 17ish in town running empty he has a programmer but I am not sure witch one it is.

 

I would have to see it with my own 2 eyes to believe that it can get 18 mpg hauling a 30 foot toy hauler. OK maybe it can going down a 10 mile long 7% grade with 75 mph tail wind
