Default Gas Mileage Eco/Alum. body

How's the gas mileage on the new Ecoboost/Alum. bodied trucks?

That's a pretty open ended question with all the different engine / gearing options. For example, a 3.55 runs about 15% more RPM's on the highway than my 3.31, for exactly the same speed, but that doesn't translate to 15% less fuel used, because the 3.31 has less torque b/c of less RPM's, and uses more boost. From what I can see, 400 rpm's = a 2 lb. reduction in boost, give or take.

Also, my '16 weighs ~400 lbs. less than my '11, probably because I went from a SCab to a SCrew.

Anyways, this is from a work trip that I did this week. Kalamazoo, MI to Chicago to Indianapolis to Muncie, IN and back to Kalamazoo. Temps in the 30's - 50's. Cruise set at 77 mph for ~500 miles of the drive. ~100 miles on country roads at 62 mph, and the rest on the job site and in town. Slight headwinds / crosswinds, or else I'd have probably gotten closer to 20.5 mpg.

I'm quite pleased with the economy on this truck thus far. ~16k miles into driving it, and 18.522 mpg life to date. Truck averages .45 mpg better on its calculation than it does when I track it by hand, so what I really got on this trip was 19.55 mpg.

Wife's brother just bought a '16 Lariat 4x4 with the 3.5 and 3.55's. He's getting 19 to 20 mpg hwy and 17 city. If he'd slow down a bit I'm sure he would get 1 to 2 mpg more!

I get right around 17 average, but I also have A/T tires on so that could be making a difference.

Literally so many factors to this statement. What kind of 400 hp motor is it?

Hello, just purchased a new 16 F150 XLT 4x4 Sport 2.7L EcoBoost. I kind of feel ripped off after seeing the above averages. I have put on about 200 miles and I am averaging just over 14 mpg. I was hoping I would at least come close to 18 or get somewhat better mileage from my Toyota which averaged 17.

how many miles on the truck? 200? It should go up after around 2k miles.

14mpgs during regular driving is not good, unless you've lowered the gearing a lot and added great big tires and lift.

If your truck is stock and broken in and you're not towing or hauling...and still getting 14ish, then go to the dealer and have them take a look.

I only have 320 miles on it currently. 120 of that freeway miles. No towing and very easy on the pedal. But your words bring some comfort knowing my mileage will eventually improve. Thanks!
