Fuel Consumption
I have a 1989 f250 larrit with a 460 EFI , E4OD, 3.55 gears. I have a
rebuilt engine with less than 3000, and I am only getting 8mpg, does
anyone have any suggestion on improving my mpg.

I was looking at getting 10-12. I sold a 1997 f250LD with a 5.4 and
3.73 gears and bought this 89 because I needed something that would
pull my RV better. What did you pull with the f450 and did the mpg
change from no load to a load.

i have 1993 f250 460ci i got 8mpg no matter if i drove it nice or ran the **** outa it. 7 with a 26 foot trailor. i just re-built it and should top out at 11 or 12 but i have it bored 30 over, rv cam, only 33" tires, and a new timing chain that advanced my timing. idk what youve got but inless you want to spend a bunch of money and replace your intake manifold , upper plenum, and air box your not getting more than 12.

my 78 f150 camper special w/460 and c6 got around...well, i dont know for sure, i never did the math....didnt want to know......but it took me a 1/4 tank to drive across town, empty or loaded....out on the open road, if i kept it around 55mph it seemed to be around 15mpg or so, 1/4 tank would get me around 60 miles round trip....

3:73 gears i believe, stock size tires, motor dialed in for low end torque....pulled race car trailer, edelbrock performer cam/intake/carb package, headers......
remember...i said i never did the math, just took me 1/4 tank(rear) to go 60 miles round trip on open road....driving like grandma and keeping it at or near 55.....
just dawned on me that rear tank was 19 gallon i think.....that works out to around 12.5-13....i went off 16 gallon for front before

My 97 with 460 and 4:10 gears stock got about 13 MPG on highway empty or pulling a boat but after I lifted it and went to 35" tires it went to about 6 MPG I didn't think a couple sizes of tires would hurt it that bad

91 ford F250 460 3/4 ton 4X4
I picked up a 91 ford f250 Fuel injected 460, it is a 4 wheel drive 3/4 ton. I bought it a couple of weeks ago so far I have been getting 9 miles per gallon. That is babying it. I havent loaded it up yet so I dont know what it will do loaded. I heard these 460 engines use the same amount of gas loaded or unloaded. I hope so because I don't look foward to 6 miles per gallon when the gas prices rise again.
