Not getting good gas mileage on EcoBoost Engine

I just bought the ecoboost myself. Salesman told me that once I get it broke in, it'll get the right results. Time will tell.

From what I have read almost all of the complaints are that the mileage actually diminishes over time...I hope yours fares better!

I was hoping it would improve... I took delivery on an XLT SuperCab EcoBoost on Wednesday, and the mileage overall went up from 13 to 17.5 when I took it on the highway for about 60 miles. You're right, though, time will tell.

I have an '12 KR 4x4 crew cab with the EcoBoost and now with 10,000 on it I still only get 14.8 to 15.2 in town and on the highway.....This sucks.....Love the truck but the gas costs are going to kill me.....Is this what I am to expect? Thanks from a new member.

2012 F150 4x4, 373 rear end. I drive 120 miles to work, each way, every day. Its all Ohio turnpike with the exception of on the six miles to the pike entrance, and the two miles from the pike to my office. On a good day on the highway, I have been able to get 16.9 mpg. That's only when I wait until I get up to turnpike speed (70 mph), set the cruise, and reset the calculator. I know we are all told to wait until the engine breaks in. I have 31000 miles and I am still waiting. On the days that I get a 10 mile and hour or greater head wind, I am down into the 13's. I traded in my 5.4 Triton for this. Mistake.
