    I take it that is towing mileage? If not you need to take it back to the dealer and get it checked out. My 4.6L 2010 F150 gets that mpg towing a 16 ft with 2 Ztrs push mower and all the other stuff. It gets around 18 with mixed hwy and city driving. 20 to 22 straight hwy.

    not towing mileage, baby foot non tow mileage. Last f-150 with the 5.4 was anything to dream about either. Old mans 2010 4.6 3v gets about 17mpg. I have had three f-150's dating to 2005 and none of them have achieved more than 15mpg, even with 30000 plus miles. Guess I shouldve brought those to the dealer also!

    Umm. No you should have driven Chevrolet or GMC 1500 then. Ford's mpg's have always been less than GM until the 3v was put in the Ford in 09'.

    My wife also has the F150 4.6 3v Super Crew and it avg the same 18 mpg's. So that is what I was basing the fact that you need to take it back to dealer on. Maybe the 5.0 is just a gas hog though.

    All your high tech theorizing is wonderful, but in the real world a EB towing will see high exhaust temps , the computer will then pull back timing and fatten up the A/F and the mileage will be in the crapper. The 5.0 is a better engine for towing if you want MPG.

    i think i would get that too if i coasted downhill. It does go into the shop tomorrow though but not for mileage. Frustrated that it gets poor gas mileage but not that frustrated as gas is not a factor of why i bought it.

    The irony of you telling me my theorizing is wonderful when you fire back with theorizing is excellent. ;)

    The only test that I have found that would be "real world" comes from Pickuptrucks.com and the reviews do not cover the same roads traveled.

    The Ecoboost averaged 8.5mpg during their crossing of the Rockies while towing a 9000 pound trailer. The 5.0L averaged 9.42mpg over a much shorter 226 mile test. So I don't think many would consider 1mpg as being "in the crapper" considering the testing conditions for the Ecoboost were certainly more rigorous than driving a landscape trailer around town. ;)

    No theory involved. Fords engineer as reported in the PUC dyno tests and written up by Mike Levine stipulates that when loaded the ECO backs the timing and A/F ratios down due to high exhaust temps in 3+ gears. There goes your fuel mileage and this is why Ford recommends Premium fuel in high temps or when towing with the 3.5. I actually own and tow with a 5.0 and the guy who sold me mine also owns a Eco-boost as well as is a LCO. When towing similar loads in similar conditions the 5.0 consistently gets better fuel mileage. For towing daily with loads suited for a 1/2 ton the 5.0 is a better choice for fuel mileage. Regarding towing 9000 lb loads, wrong truck for that application.

    I get the same mileage with my 5.4, I usually get about 13mpg's when I tow 7K. But I mostly average 15 mpg around town unloaded.
