I have been commuting to work in my 2012 F150 XL 5.0L Regular cab with the 8' bed. It is a 50 mile round trip to work and back and I rarely drive my truck on the weekends. I have tracked the gas mileage for the last five months and am averaging 18.2 MPG with 1/2 city and 1/2 freeway driving.

Reason: Forgot to list the engine size.
i dont remember what i got in my 2011 when it was new. But the 2014 i have the mileage on the computer for the stx is way worse. I have less than 1000 miles on it, so im hoping its just the "new motor" phase and the mileage will only get better. Im barely averaging 15mpg 50/50. I got no better than 18mpg on a 400 mile round trip all highway last weekend, my 2011 would average over 20mpg.
I usually get 15mpg highway until a couple weeks ago.
'Running S on 81 400 miles got up to 19.2
Averaged 18.7 for the round trip of 800miles.
15000 miles on truck
Hopefully it stays there

Sorry posted in the wrong thread and can't figure out how to delete my post
Well my awesome mileage dropped to around 16.5, but on the upside, my truck looks great on the level and 33 x 12 Duratracs that caused the mileage drop!
Im hoping this is just because the engine is still fairly new. Im bairly breaking 13.5mpg on mostly highway. Truck just seems to eat gas a helleva lot more than my 2011 did. I know its a little more heavy being a screw compared to a scab, but dam. I was getting high 16's and 17's on highway average.
Just back from a 1500 mile trip and very pleased with the mileage. I averaged over 75 mph for the trip based on miles traveled/time including stops. Traffic was flying and the trip was through KY, TN, GA, so lots of hills. The truck returned a hand calculated average of 17.8 down and 17.5 back. It's a 5.0 stx SC 4wd with 3.55 gears so I am plenty happy for how hard I was driving.
I own a 2012 F150, super crew 4x4, 6' 1/2 bed, 3.55 rear axle, with a 5.0 liter. It has 3,500 km (2200 miles) and I am getting 12L/100kms (19.5 US mpg) Highway, 16.5L/100km (14.2 US mpg) City and Combined 14.1 L/100 km (16.5 US mpg).
Can anyone tell me if this is the average fuel economy for the 5 liter? I have put in a K&N air filter in, a Bakflip F1 tonneau cover and nitrogen in the tires.
I am hope to still get better fuel economy out of the 5 liter.
You could check Fuelly (see link below) to see what others are getting with your engine. EPA also allows users to submit their actually experience.
There is not a lot you can do. Slow down is the biggest thing. You could look at low rolling resistance tires, and make sure the pressure stays up to Ford recommended value. Nitrogen helps as it leaks out slower, but nitrogen in itself has no effect on fuel economy. It is the pressure that counts. Oil will make a small difference. I believe your engine may be approved for a 0W-20. It will help some. Penzoil Ultra is probably one of the best. But the biggest is speed. Did I say slow down?
