i can't post in the f-150 thread cause i'm just a basic.......but my son bought a platinum ecoboost about a month ago and i bought an xlt with the 5.0 two weeks ago....his is a crew cab, mine a super cab because i needed a longer bed than the 5.5 he has....he has 3.55 gears, mine is 3.73...his mileage around town is between 14-15, mine is 16-17....road trips where we're mostly on cruise control, his best is 19.5, where mine is 22.5....around town mileage is largely influenced by the driver, so that maybe accounts for that difference....but out on the road, with the cruise set, that's just the machine.....comparisons were run at 60 mph....just my truck gets 17-17.5 at 75 mph.....22.5 at 60 mph....65 still gets me 21-22, but anything over 65, it drops off fast.....he was thinking he would get better mileage on the road, hence the ecoboost...had he known what real world would give him, he wished he'd bought the 6.2 and taken a little less mileage in exchange for the power and fun factor of the 6.2....he says next year is a raptor with the 6.2
