The longer the bed the more you would benefit I would think, I would guess a tiny 1" spoiler that breaks the airflow at the rear might help. One problem always seems to get replaced by another problem. I have the shortest bed (5.5') and it catches air, as it moves things around, if not secured down.

Just got the second tank run through.

11.6L/100km or 20.2 US mpg

I'll take that.

Lets try a tank in sport mode

Here's an interesting read I came across today:

Good ole Ford. Yeah, my F150 is the LAST Ford I will ever buy, and, not for a good reason. I've had my F150 in the shop for more days than my 3 previous Chevys.

Have wondered what other were getting for mileage. Mine is an 018, 4X4-FX4, 3.5L, max tow, deal installed leveling kit w/ Fuel wheels shoed w/ Nitto LT295/55R20 Ridge Grapplers. Truck is driven 80% on freeway here in the Texas DFW area. Current mileage average showing in the display is 15.9, just over 6K on the odometer. Made a run to the hunting property this weekend carrying only me & clothes for a night. Now there was a nasty head wind of 30mph+, posted speed limit of 75, got 12.5 on this tank for that drive - really?!! Like the truck but you'll get no encouragement from me to buy one for claimed milage

I get great mileage with a 5.0 and 3.55's and 4wd. Using BP fuel(some odd reason BP gets the best mileage) and Im getting 17 mpg in mostly city driving

If you want EPA mileage, you have to drive to EPA standards. Sustained speed of 60 MPH, average speed 48 MPH, with a burst of 80 MPH to simulate passing. Doing 75 MPH sustained, you will not get EPA. My Garmin records average speed, and over 170K miles recorded since I got it, my average speed is 51 MPH, I drive on 55 MPH roads at 60-62 MPH using cruise. My truck is getting 20 MPG, in winter. When I get on the interstate and drive 70 MPH, it will drop to 17-18 or so.

So complain all you want, its what it is, no matter WHO manufactures the vehicle, the EPA ratings are set to no more than 60 MPH. Drive above that speed, and it will drop.

Default Just picked up my 18 lariat 4x4 supercrew 2.7 And the fuel mileage is terriable.

I just took delivery of my new 18 lariat 2.7 supercrew and the fuel mileage is terriable. I picked up the truck from a dealer about 700 km away from where I am and averaged 15L/100km or 15 mpg. Since then Iíve done mostly city driving with the odd Hwy stint mixed in. Currently have 2600 kms on the truck and according to the read out on the truck Iím at 16L/100km. Hand calculated is 18.L/100km or 13 mpg. A far cry from the epa rating of 12L/100city and 9.8 hwy. it is cold here and winter gas but still shouldnít be this bad. My 04 f350 powerstroke that I traded in got the same mileage. Almost wish I still had that truck. Other issues Iíve noticed is really bad body lines box sides are reallly waves and the door handle pockets are terriable

Your first issue is it is winter, second it is a brand new truck. Put the two together and you get crap for MPG. Wait for spring, do a PCM reset (disconnect battery for 15 minutes), fill tank with premium for at least 2 or more tanks, then drive it. Take a nice highway cruise of 65 MPH or lower using the cruise control, and watch the numbers climb. The truck learns over time and with the bad cold weather and crappy winter gas, it learns to guzzle.

Fair enough thatís kinda what I was thinking but it still sucks. The only other thing that kind of came to mind is that the auto start/stop doesnít always work. It will say itís too cold at -5c then the next day itís -20 and it works for a few times then doesnít. Is there a temp sensor somewhere. Maybe if it thinks itís colder than it is it could be running rich? When auto stop is working it does seem like it gets better mileage
