What is your secret?? I have a '96 F150 5.8 4x4 standard cab short bed with 140,000 miles and I'm lucky if I get 10 in town and 12 on the highway! I have a K&N air filter, currently running 31x10.5 all terrains. About to get some 32x11.5 m/ts and don't even wanna think about what my mileage will be like then...

96 Supercab shortbed, stock 351W, E4OD, 4x4, 3.55 gears, 31x10.50 all terrains.

I'm averaging 15.5 around town, 17.3+ on the highway.

94 5.8 4x4 extended cab short bed, stock mags and tire size, I don't have town and hwy sperate but on my last full up I averaged 13.8 but I need to reset my computer (high idle issue that's resolved) and I think it will go up a tad. No mods.

I get about 15 on highway, 11-12 in town. 351w. My 7.3 powerstroke is a different story. I'm getting about 19 in town with just a tuner. I wish we could tune these old 351s. My buddies 12 valve cummins, he has a bunch of mods to it, he's getting close to 32mpg. With 500 rwhp

I filled up when I bought my truck b/c I had a 250 mile drive. It was windy and the interstate speed limit was 70mph so I wasn't going under that much and it was hilly up and down. I didn't expect much going that fast plus up and down big hills. I haven't checked it since then b/c I've been putting in 5 gal at a time b/c the front tank guage doesn't work BUT the mileage on the way home was a measily 12mpg. I would suspect it might get 15 if I'm lucky and driving under 70 on flat ground w/ not a lot of wind.

been getting around 12 with mostly city driving, on my recent move from so cal to nor cal I averaged just under 17 cruising abot 60, this includes the ride over the vine, was very happy, truck seems like it is hitting its grove

For a unknown reason at this time I'm only getting 12.5 both city and highway. I'm being told it's the ethanol, but I was getting closer to 18 highway last year. 30% sounds a bit much to lose over a skosh of ethanol.

1994 5.8L RWD Auto (E40D) Dual Tank (20 & 18 I believe)
303,XXX miles
Completely stock, mostly original
87 octane (no eth)
Keep both tanks full, when one is empty I switch then top both off within a day or two while still drawing from the mostly older tank.
13.9 in town
16.2 highway

Usually in town I drive like an old man because I use my truck to carry lawn care equipment. Highway it's usually CC set at speed limit +5mph and the highway mpg was taken before I changed my plugs/wires/rotor/cap/coil/cleaned TB a month or two ago. This beast don't usually get out on the highway because I have plenty of vehicles that get decent mpg to use for longer drives.

My lightning gets around 13 city 17 highway, and it's a little built. But once you get on it you can just watch the gauge needle go down, I think they're good on gas mileage for what they are, IMO one of the best engines ford made.

I get about 13 city and 15 highway with 33x1250s and a front end level.
