Here's a pic I took of my 2012 Ecoboost Lariat Supercrew w/6.5' bed & Max Tow on the way to trade it in for my Duramax. Just ran it at 60mph and was averaging 22.2 mpg. I found throughout having the truck that the computer and hand calculated difference was about .2 mpg. This wasn't an anomaly either, this was pretty much how it was as long as I didn't drive it aggressively or too fast. There wasn't much of a difference between Regular or Premium.

I have found that running a tune on the Ecoboost (5star tune) that really makes the vehicle come alive.. I get 11.5 towing at 60mph most trips.

That's pretty good. I was averaging low to mid 10's with the EB and our 28DSBH.

There are times where I miss that truck - it was fun to drive and felt nimble for its size. The Roadmaster Suspension helped cornering a lot, plus got rid of the shuddering on launch.

What am I doing wrong?
I live at 5,000 feet above sea level in CO. I have a 2014 ford f150 ecoboost with tt - heavy duty tow package 6.5' bed and super crew cab. When not towing I get 16-17 MPG max using 91 octane brand name fuel... I drive conservatively. When I tow with loaded trailer (including full fresh water tank) I'm at about 9875 lbs - I also have WDH and a tongue weight of 1000 lbs. with headwind I get between 6 and 7 mpg (at 65mph) and with tail wind I get about 7.5 to 8.5 mpg. I run full synthetic Castrol Edge oil, performance oil filter and just got a K&N performance air filter.
Anyone have suggestions as to why my MPG is so much lower than everyone else's ? I love this truck for commute and towing ! Just curious if some how my engine isn't running as efficient as all others I read about on forums....

I usually stay in CO but recently drove to NV to camp for a week and was a little surprised at the low MPG on the trip.

Eventdude,

Just curious how fast you're driving when towing. I found a steady difference in fuel economy between 65 and 60 when towing our White Hawk. When windy I locked out the 6th gear and kept the needle steady. Also do you make sure your TT and Ecoboost tires are properly inflated? Just throwing some ideas out there.

It blow's my mind what people are towing with the EcoBoost. After the Tahoe and Super Duty wear out, I think one will be in my driveway. I rented a 2014 while in NY a few weeks ago, and I tell you what, that truck ran like a scared rabbit. I snapped a pic of this rig this past weekend waiting for a spot to open.

I've seen a couple of 5er/EcoBoost combos.

Have to remember that it's still a 1/2 ton truck around that engine. Payload has to be considered.

The guy in that pic has got to be at his max payload or over it.

Max payload package perhaps.

I love my truck, I have 43k miles and typically get 9-10 on the highway towing the trailer, coming back from Michigan the other weekend I got 12 and that was mainly on 2 lane roads. One of my big mileage issues is how I set the weight distribution hitch, it can effect the mileage by 1 mile per gallon.
