If you have the 3.7 it's not an Ecoboost. The Ecoboost is the 3.5. Need more details......tires, lift, driving conditions, etc.

It's 3.5 sorry. Definitely ecoboost, Limited model only comes with this engine. I drive city and highway combo. I've tried to use premium gas, doesn't matter still around 14.7 almost every fill up. No modifications to the truck.

Shooottttt. Join the club. My 2013 limited gets 9 mpg around town. 12-13 on the highway. 3500 miles. I run 2wd as much as possible. If not I run the auto 4wd. I park in a heated garage. The 3.5L Eco is garbage mileage. My buddy with his 2013 5.0 gets way better with an average of 18. My lifetime average is 10.3. I have 305/40r22 cooper zeon LTZ's. Cat back 4" strait pipe. Otherwise. It's factory. Super disappointed. I would of bought a platinum with the 6.2 had I known better.

This is a long running topic on here. Welcome but you have just fueled the flames. It seems once one of these threads slow down another pops up.

Btw, I get good mpg with mine, I even tried making bad mpg and still got about 17

Well I am sorry guys but you guys know these trucks run 50k. I still have the sticker that said 16 city 22 highway 18 average. Don't get me wrong I love the truck. It's comfortable, it's got beautiful interior, but if I knew how bad the gas mileage was gonna be that I couldn't even get 15, I would have got a Range Rover.

12.9 average here at 24,000 or so miles. Thing sucks at gas mileage. And I also would have bought the range rover seeing the mileage i've gotten so far (that was my other choice)

Mine is a 2013 Limited 4WD, think most if not all have the 3.73 rear end. I have less than 700 miles on mine and the truck indicates around 19@60mph, 70 degrees outside, Texas flat road and winter mix gas (NOTE: This is crusing and hitting reset on the trip and driving for about 30 minutes). 15 in town stop/go traffic. Some say their plugs were not gapped .030 and were getting poor MPG. Are you using remote start frequently?
