Fuel Mileage??
I have a 1978 Ford F-150 xlt with a 351M and i'm just curious to see what others are getting in fuel mileage for the same Truck or what i should be getting? I'm getting about 12 miles to the gallon.
Thanks in advance

Things that affect Fuel economy:
State of & efficiency of engine(if in tune,mileage,etc.)
Quality of fuel
City stop and go driving
Highway driving
Hilly roadways
Ratio of rear end
Trans Gear ratios
Jack rabbit driving habit
If there is an Egg under the accelerator pedal?
Weight of vehicle

Fuel Mileage??
I have a '77 4x4 Ranger with a 351m that used to get around 8 to 10mpg. She has an AT and 33x12.5x15" tires. She was never timed except by ear, needs a new carb and has since worked her way down to about 6 to 8mpg. Luckily I don't have to drive her far.

Fuel Mileage??
My 2wd 77 w/351, t-18 4speed, dual straight piped glasspack exhaust and 3.00:1 rear end gets a max of 13mpg and has 168000 miles on it original untouched engine no carb or engine work for over 10 years. engine uses a quart of oil every 1000 miles or so.
My 4wd 79 w/351, c6 auto, 3 inch single flowmaster exhaust, and 3.50:1 rear end gets close to 11 -13. I am not sure because I havent tested it recently. It has only 90 miles on the heavy duty rebuilt auto and t case with new gaskets and bearings. The front wheel bearings are a month old too. The engine uses no oil and has about 600 miles on rebuilt 2150 carb. BEFORE the tranny/t-case rebuild I got EIGHT MPG!
The mechanic who rebuilt my trans said the 3rd and reverse clutches were completely gone and the yoke or u joint I think, Broke when He removed it so thats new too. That rebuild helped a lot.
And I drive in the country, hilly and stop and go between friends houses and school. I usually have my foot half throttle or more and go about 50 to 70. Yes I am a maniac
