I have a 97 f250 ( 4 inch exhaust, 10k mod, napa filter , FPR shim) with f350 suspention, dana 60 front, heavy rear leafs ect. I have 3.55 and a zf5 and im turning just under 2200 @ 75, about ~1400 @ 50. I have owned the truck for ~ 4 tanks of gas so far @ these are my reported gas mileage
1- 21.9 MPG ( drive home mostly back road @ 60mph speed limit, some hills)
2-17.5 MPG Around town ( just got the truck and was messing around, revving it up much more then I really needed to unloaded...the turbo is fun)
3- 18.6 (Driving mostly to work and back...once again back roads were the speed limit is 50mph, and its not flat, hills ect)
4 - 19.9 ( Driving to work more, with a solid 50ish miles of highway ( went to help my friend get things out of his truck he crashed)
-----Each fillup is approx after 200 miles and I fill at same gas pump until it click off. I have had no reason to drive highway so I do not have any idea what I would get, i'm assuming a solid 23 honestly.
-----My driving style is very laid back, I realize the truck will not be fast, so why push it and throw my mileage down the drain? I start off in second most of the time, and shift into third before applying much throttle, i then accelerate and shift at 1400ish rpm's unless im going up a hill or trying to accelerate.
I do not lug the engine( I like to be ~ 1300-1500 rpm when driving), I feel , if i'm lugging the engine and have 1/2 throttle i feel im buring more then if im at 1500 rpm at 1/4 throttle ( is this correct?)
take it easy, breath.. these engines will sip the fuel ( i would say i also leave my truck idling approx 1-2 hours per tank. Anything under 5 mins I wouldn't dream of shutting her down. Anything over 20, I think about it....and i really hate when somthing is supposed to take 10 mins' then an hour later i walk out and shut the truck off -_-
