Average 23, gotten as good as 27.

well Palmer you are doing good get that much mileage i have owen 5 these trucks and never get got that

Thats what everyone tells me. I find that I get 23 when driving about 110kms, seems to be where the motor likes to run and it never upshifts or downshifts on hills or climbs. If I don't run fuel conditioner or cetane boost I sure notice a difference.:rocking:

I have to agree with crazy. I have had 4 of them and the best I have ever got was 19.5 and that was with the second biggest one I have had. The smallest 6.5 truck I had was a light 3/4ton 2wd and it got the worst at 14. Most of them seam to average around 18.

I'm getting 14-15 around town and last highway trip (not all interstate hwy) 19.8 w/no load on board. 94 6.5 td 2500 x-cab :choochoo:4x4 longbed.

Well, for the non believers, I got 675km out of a tank on the highway and about a 100 km city driving yesterday. When I got home this morning I put in 85 litres. Thats around 24mpg.:tu:

That was driving around 105 to 110 km/h

I'm not a non believer if you say thats what you get I will take it at that. It's just incredibly good and you should probably sell the truck to me.

Anywhere from 13 to 18

Haha, yeah maybe I should do that. Only I've built it up to the truck I want and to do that to another one would hurt my bank account LOL
:c:

what about y'all dually folks... what mpg are y'all gettin?
