Bone stock on 3.73's, I'm currently getting about 13.5~14mpg hand-calc'd around town driving like a granny, and I max out around 17mpg hand-calc'd on straight freeway at 65mph.... Since getting my Michelin LTX AT2 tires, my mpgs have dropped a bit. I was getting about 0.5mpg better mpgs with stock BFG's

2005 Extended Cab FX4 - 16.0 MPG is the absolute best i can get out of it. My commute is mostly highway. Only mods are flows and K/N filter.

07 FX4 super crew with 12" x 34" on 17" rims and leveled with a 1" rise in rear. Mixed driving, hills, flats and city. The best I can get is 14 mpg. Doesn't matter if I'm towing a trailer or running empty. Towing drops mpg to 13.

My then 07F150XLT 4x4/3:73 axles/17" all-season tires avg was 17.5 highway/12 city.
This 10F150 is way better even with the 5.4L and with 3:55 axles and the 6-sp auto, really makes a big difference.

06 F150, 5.4L EC XLT 4x4 6.5' bed with 265/70 17's and 3.55 gears. Highway it has gotten as high as 17.7 driving 60-65 mph and around 16.8 driving 70 on the interstate. Mileage has dropped some, so I'm going to check for leaky injectors when the weather gets warmer again. It's not my daily driver so I can wait on that. Towing I get from 9.5 to 10.5 depending on terrain. On the flat running 60mph it'll get 10.5 towing. Running interstate at 65-70 mph it gets around 9.5-9.8 mpg. That's towing a 20' enclosed car hauler with a Mustang inside. I've never really checked mileage in town only. but mixed driving it gets around 15 mpg.

2008 supercrew shortbed lariat 3.55's 2WD i havent had it long.

highway
is pretty good, i took an 80 mile trip at 55-65 and kept it in the 21-22 mpg area
I took a bigger trip going 80 the whole way and kept it at 18!

in town
i let it warm up a lot and i noticed that the mpg counter counts down sitting still(makes sense i guess) this week strictly in town it was at 13 and its built up to 15(ive been gunning it a bunch this week too)

i still would like to do the gotts mod, upgrade coils, get a programmer, leveling kit and bigger tires (make the final drive ratio better and i think the factory tires look tiny) and hopefully improve a lot of performance and mileage.
