I have the same year, engine, and transmission ratio, and over 13k miles my average fuel economy combined is less than 15. Yours will be too. Get used to it, and enjoy the truck, it's great.

Well yours its getting better than mine.... 3.55's, tonnue cover, stock size tires, no mods to my truck at all.


Over the 18k miles on it currently it sits at a lifetime of 14.0 MPG.... And the real pisser is the true mileage is actually WORSE than that as the truck says I use about 1.5-2 gallons less per fillup than what the truck actually takes to refill so in reality my lifetime average is realistically more like 13.8.


I made one trip from NY to KY and back it got 17.2 on that and that was the best the truck has EVER seen on a tank of gas and that was 1400 miles worth of highway driving....


last month I was towing a 1800 lb V nose aluminum enclosed trailer between 75-80mph it got a whopping 8.0 mpg.....


This truck has been a pretty big let down in many areas for me....
