The Ultimate MPG thread.
@coco38 Have you checked the brakes for drag? I agree your mileage should be better than what you're getting. Other questions are:
- what are the gear ratios?
- Is there a "tune" in the engine?
- Check air filter
- Is it a 4x4?
- tire pressure
- What are the tires....stock, oversize.... tread?
- Did you buy from a dealer or private party? Can you talk to the previous owner?
- What is the mileage on the vehicle?
- Take the VIN and look up the original window sticker to see the options "as built" and check for modifications done since.

@coco38 Thanks for posting! Good looking truck but the mileage surprises me. We have 3:55 gears under our ride. This past week coming back from Michigan we got on the plus side of 20.5 mpg doing 68'ish mph on the interstate in "ECO" mode on the 10 speed trans. Have you tried the "wipe & re-learn" suggested by acdii? It can't hurt. I run 38 psi ( cold ) in our Goodyear tires. Again, best of luck and keep us posted.
Wondering if your truck "coasts" as good as your buddies. Thinking that maybe your front hubs might be engaged. If I remember correctly there is a vacuum system that disengages the front hubs if you're not in 4A or 4H. Excuse me if I have this wrong. I was shock how far our F-150's can coast once you take your foot off the gas.

I have never done a "wipe and relearn" but here is a you tube video link I just watched by Fordtechmakuloco
Please investigate more before you attempt. I had no idea it was this detailed. Maybe a search on this forum would be beneficial.

Just added a K&n filter air flow kit to my 2011. Sounds great! Now if I can only keep my foot off the gas I should see mpg go up

I just stumbled onto this thread and found it quite interesting. Way back in 2012 it seems this was the topic of the day. Things change and our dependence on foreign is no longer a factor. Our trucks aren't or at least shouldn't be the gas hogs they once were. Assuming of course you put out the $40g's to get something considered modern these days.
I drive a 16 SCREW with the not so popular NA 3.5 "flexfuel". I routinely get 20 plus MPG. And it computes out that way on a calculator. At least within .3 or .4 MPG. It's two wheel drive and I drive it with the traffic which these days is usually as fast as the leader feels he/she can get away with. That would be 79 MPH. The truck has 98k on it and I usually burn regular unleaded gas. Only a few times have I took the plunge and tried the Alcohol blends and was quite surprised as the MPG really didn't suffer as much as I expected.
I've read a lot of the posts. Agree with some, not so much with others. I think personally think the secret is simply easy on the gas and light on the brakes. However I disagree with some in that I tend to lay off the brakes as late as possible. Drives the wife silly sometimes but I still have the original pads and rotors. Heat build up is what kills brake parts and a long steady drag is the worse thing you can do.
In the case of the engine. Coming from an aviation background where turbocharging is sometimes necessary but always avoided if possible, I intentionally stayed away from the ECO engines. Just my opinion and I'm sure Ford has done there work perfecting the gadgets. But, being a low lander I saw no benefit in them for me. This engine produces all the power I need. Pulling a heavy boat it performs as well as I need. Keeps up with the traffic and does well in the Tennessee/Georgia hills where we live.
So my two cents is, the extra cost of the twin turbo power hits your pocket book in more ways than just the window sticker. Too bad Ford has decided this is all they can offer. But, they produce what folks want. I'm OK with that too.

Run 1.5 tanks since picking up the truck, averaging 18.5 it seems. I have had stretches in excess of 22 mpg, and peaked it out at 24.7 after the first fill-up and 20 mile drive home in eco mode.
