Mileage
Know it's a little out of this forum, but my 1976 Mercury
Grand Marquis with 80,000 original miles gets 11.5 in town
and 14-15 on the highway at 70mph. It has 2.75 gears
and weighs 4825 lbs with me in it and full fluids.

I get about 8-9 mpg 
with my 460 F-250 2wd with 3" magna-flow exhuast being the only mod. I still get the same mpg pulling a inclosed 18' irailer loaded with ATVs, full gear, and gas.

I've ranged from 4.8 mpg to 17.9. I normally get 8-9 around town (Pittsburgh is hilly, all gas & brakes) and 14-15 on the highway.
But that time I got 4.8 sure was fun!
Oh, and mine was 4880 on the scales.
My 97 F250HD seems to get just over 10 in town; 4.10s, 5-speed, 4wd, supercab and mostly winter use so far.

My 86 F350 crew cab DRW with 3.55 gears and 116K on it gets 10 mpg empty and around 7.5 mpg towing a 30' 5th wheel. Mileage varies depending on wind direction and speed when towing. Like most, I didn't buy it for economy but to tow the trailer.

Help!
I just got a 1994 F250, XLT extended cab,automatic with overdrive, full bed, 1 ton suspension, 460 ci.
my city miles are maybe 4 or 5 mpg....is this normal? Iv owned many f250's before but all of them 351's. I knew my mpg would be low but this is ridiculous! Is there somthing wrong? It runs pretty smooth so i dont think it needs a tune up. Tires look good, sounds pretty smmoth all around. but 4 mpg in the city? with NO load?
any advice? I LOVE this truck. power everything....But i cant afford 4mpg i need at least 10mpg

Are there any tricks to raise the mpg on 460ci?

My old 77 F150 460 w/ 3.55 gears, welded diffs, 44" Hawgs, heavy engine mods over 500+hp, auto trans would normally not get far enough from home to give a damn about the gas milage. It was an off-road truck but street legal. I could hunt for a day and need to fell up the tank again to go look for dogs at night and never get more than 15 miles from home. The only trip a took with it was to the beach each year for beach week. I had about a 25 gallon tank and the beach is 200 miles away. I would leave the farm with a full tank. Stop at the 1/3 mark and refill. Stop at the 2/3 mark and refill. Get to the beach and fill up before I could go cruising on beach road.
75 gallons for 200 miles is 2.6 mpg on the highway. I never measured it towing or in town for good reason, I didn't do any of that.
