Guess.
After I had it running right seems 11ish in town and 14ish highway if I was driving right . The way I drive it was usually 9 and 12 ish. Truck did not seem to be load sensitive unless just really running heavy ............. then good golly miss Molly hide the gas receipts Momma gonna be pissed LOL.My mom had a 85ish F150 with the 351. Thing got like 6 to 8 mpg. OY!!!
Current ride is a 2020 F-250 with a 3" lift, offroad package with skid plates, leather and all the bells and whistles running 4:30 gears, 10 speed transmission, and a 430 HP gasser. 13.6 MPG when not towing in mostly Hwy but some city driving. It's an old style push rod engine. Pop the hood and you can see all the spark plugs just like in the old days.Had a 97 f-250 that was a beast. Just had to replace the body mounts and paint it to have it back to "nice truck" stage. Only thing that would have been better is if it would have been a diesel, the 351 loved the go sauce . POS stole it and parked it under a 350 welding rig in a ditch at Overholser .......... Miss that beast.

Dad had an 89 f250 with a 460 EFI. Talk about a beast. It would pull his 30 ft travel trailer up mountains in Colorado and pass cars while doing it.Had a 97 f-250 that was a beast.
