Best mpg is with the motor off . Seriously though, the best I can tell is these trucks will get 15-17 mpg cruising. Getting TO cruising speed (40-70+) is what kills that mpg. Even with a light foot on the gas. My max around town is probably 13, Highway 17 (once). But for the most part, the evic on mine shows 10.
As far as getting better mpg? Correct tire pressure, clean air filter, clean fluids...all the normal fuel economy tips should come into play and possibly help. Oh, my truck is pretty thirsty above 70 and has a full blown drinking problem at 80.

If you call an engine a motor, stay out of my garage!!
Do I have an engine in my motorcycle?
Then why do they call it a motorcycle?
They could call it an engincycle I suppose.
But that would be as stupid as your comment.

I remember my old trucks, a 70 3/4t suburban and a 77 3/4 dodge w/400 MOTOR and they were very consistent as they always got 10mpg when not towing. I think a 3/4 HD truck with all the power the 6.4 has that gets 13/17 is pretty good. I still have my 2000 Cummins that gets 19/20 hwy not towing and costs more for its fuel and oil not to mention $5k more otd is considered good for its economy. If I replaced it the 6.4 with the 8spd is my choice over the new Cummins without question.
In 2000 it was $5000.Actually, the cummins is a $9300 option.
