I have had an Ecoboost since October, and only have 3000 miles on it, but so far I LOVE it!
(And even in this big, lower geared 4x4, I can get 20mpg or more on trips no sweat. The average tank for me; half city, half highway gets me around 17-18mpg.)
I get 20MPG with the Tundra highway (empty), if I stay within the 65mph limit and I HAVE low gears
(To the Tundra with the 4.30 gears. With the 3.73's and the F-150s first gear at 4.17, I have a ratio of 15.55 to one in first.

(And I am pretty sure that even towing my 20ft equipment trailer, I could beat my 2005 F-150 5.4 in a drag race. :laughing
I had an '05 Lariat, Stupidcrew 5.4, 3.73's so that statement is meaningless. That 5.4 was the most anemic excuse for a truck engine I've EVER come across. I bought mine cash(no financing) and hated it so bad, I traded it for the Tundra 18 months later
