Eco Boost cost to much my 93 F250 7.3 with a 5 speed gets 19.5 mpg never would have thought it would have got that kind of milage when I bought it.
my 2004 5.4 ..gets 24 mpg with the ac on...[/quote

Only when going downhill I bet??

On flat country, driving 55ish my 2010 will get in get low 20's mpg on premium fuel. More typical driving faster and in mixed terrain, 18-19 is common. With my 24' Enclosed, in hilly country about 9.5mpg. The grade of fuel realy affects the milage on mine also when I get into the Ethanol crap it hits the pooper too. But on real gas its not bad.

I had an earlier 5.4 in an F150 4x and it got 15 at best. It is good to hear the newer ones a better. But then really, who the heck drives 55? lol!
