Best tank was 27.65 mpg. Worst was 25.10 mpg. Based on old fashioned miles/gallons at the same pump at the same station. It is G100 instead of E10 which helps.
The Information Center runs 2-7% Low (Average of 4.2%). It runs closer in cold temps and farther off in warmer temps.
This car has never returned less than 20 mpg in 5,000+ miles even when I had a 2.6 mile commute (Averaged 22.5 mpg during warmer weather) and during the initial tank (20.0 mpg) that included ring seating (Alternating High Load / High Vacuum cycles). But then I have always short shifted / skip shifted high torque engines in normal driving (I consider this simple common sense as opposed to hypermiling as a I still out pace 90% of the traffic from lights). I save the 1st gear launches and 6800 rpm powershifts for the 12.6 @ 114 track passes.
It gets 3.5 mpg better in town than my old 300 bhp 4.6L SOHC 3V. On the highway the difference is smaller. Maybe 1.5 mpg. For a V8 I think Ford did a very good job with the 5.0L DOHC 4V. I would not be surprised to see 20.0 mpg + averages for people who use some common sense in a 5000 lb 2011 F150 (Same engine detuned to 360 bhp).
Whats really sad is my Mother's 2007 Hyundai Accent Automatic. Typically 26 mpg (City with her driving) with an all time best of 31 mpg (Highway with me driving). I would say the 2011 5.0 gets about 10% worse on average.
Beats my Mustang handily and yet with all that power... I need that 5,0l roller motor with 5-speed swap...

Awesome! Fords on a roll with ecoboost,coyote,5.0.
Glad your having fun with what most consider a "earth killing muscle car" LOL!
Can't wait for a few years when all this technology ends up in junkyards!
