Default 6.2 mpg ?

only have 50 miles on mine and almost no highway driving but only sitting at 11 MPG. how many miles are you 6.2 guys seeing on the truck before you've noticed descent MPG?

First tank in my truck I averaged about 15 MPG. Lowest I've ever seen was about 13 and that was through the winter using 4WD.

It's not a Honda, you ain't going to get mileage. I've got about 11 thousand on mine and it's been consistant at 13.3.

i know it's not a honda. 11 and 13 is a bit crazy. the window sticker calls for 13-18 and some of the peeps on here are reporting 15-20. just seeing if they experienced low mpg during break in before seeing 15-20.

I've got 1,050 miles on my 6.2 with 3.73 gear and have been getting 9.3 on E85. Looking forward to trying a tank of gas one of these days just to see how it does.
