I have found with mine (3.55 gears, crew, 6'4" bed, 4x4) if I run 57-61 mph it will hover in the 33 - 34 mpg range per instant evic with no wind. Once I hit interstate speeds (69-74 mph) I drop. Per evic a 220 mile trip last week showed 28.8 mpg with perfect weather conditions running 72 mph. Actual hand figured was 28.152 mpg. Overall my average over the 3800 miles is 23.331 mpg (hand figured). I have noticed side or head wind are the ecos enemy. I understand that's common but it's more noticeable when your truck normally grabs upper 20s lower 30s and the wind takes you to 22. Wind hurt my last gasser , but it went from 18-19 mpg to maybe 15 mpg.
I have a legal pad I keep in the center console and log date, gallons, price, miles driven, and the math to go with all. Evic is nice but I have found discrepancy every time (sometimes a gallon off sometimes within a tenth). Probably overkill but I like to have everything documented. The documentation could also give e me an idea if a problem is developing.
Overall, gotta love the truck! I get a kick out of the looks I get when I pull up to the diesel pump in a 1/2 ton. Lotta people ask!
