My latest was 15.68mpg. The truck did not touch the highway once for the entire tank of gas. I live in New England, hills and curves are all over the place.
She's got 114k on her, 3.55 gears and 31" tires. I have 33"s sitting in the bed right now waiting to be mounted and balanced, and 4.1x gears soon to come.
300 just gets better with age.

Guys...I had a 300 in a new 79 van that was converted for travel, the carb 300 with the auto got the same mpg as I get today ; in 91 f150/eod/efi...with three tool boxes loaded heavy for the jobs....18 mpg the best 15 the worst freeway rpms at 1800 64mph....the curb weight being equal/ the od tranni and the efi just doesn't have the effect on mpg that i expected... any comments?

When it had 31" tires, stock 3.08 gears, stock exhaust and same transmission, I think the best mileage I got was 12mpg, also mixed highway/city. You just can't tell with these motors.
How'd you like those 31" tires with that 3.08? Im consdering going to 16" rims with 31.5" tires (265/75R16) and I want to now how far down I'll need to re-gear...and how soon.

Speedo Driven Gears
Just remember; those of us that change our tire size (different circumference) and/or rear end ratio from stock configuration, and don't bother to change the speedo driven gear are going to get incorrect readings in both actual mph and distance.
And get different mpg readings also.
Just thought I throw that in.

it seems to me like i can drive around the block and the gas gauge goes down.

wow. i just did some research. in my earlier posts, i stated i had a 4.10 in my 300. the Vin Code F26 points to a T-18 and 3.55 rear end w/ no ltd slip or posi. i still get 8-10 mph highway. this is going by how much i put in and exact mileage from home to my normal destination... Good ole SRU. its a 55 mile trip 1 way. mapquest confirmed it.
