Tank is the one to tell how your fuel mileage sucks.

Id say that 18 to 20 mpg is a stretch. But then again. Ive never had anything to do with a 6.oh

I believe 18-20 in the summer with #2. #1 and cold temps kill diesel mileage

Hand calculated? Topping off to the top of the filler neck every time? Some might get 18... most do not..

She is talking about my truck

Yup had calculated. Filled up the same way every time. I get 16-17 mixed and 18-19 highway. Verified multiple times over the past year.


My brothers 03 2wd bone stock with a old super chip programmer would get 20-21 on the same trip.

my 06 would get 18 all day long before I put the lift and the big air brake above the cab LOL

our 6.7 gets 21

like it or not that what it is. All in how its set up and mostly how you drive it.

I got 19 hand calculated on every all highway trip I've made. Gotta keep her around 70mph.
