I know you didn't mention it, but will share anyway

I have the 2011 F-150 SuperCab (cab type will influence gas some I believe) with the 5.0L V8.
Highway I get high teens, city I get low teens. Since I've owned it, I've put just under 5k miles on it and my overall mpg average (based on the computer) is like 14.3, with probably 60-70% of the miles in the city.
