 I have owned my 2011 Ecoboost for 6 months now, have 8500 miles on it, and am very disappointed with the fuel mileage that Im getting (best on HWY is 15.8 & worst is 12.7, 14.075 AVG over the 8500 miles on my truck, calculations were done by hand). My 2008 Tundra was getting better mileage than my Ecoboost, and it was lifted 3 with Oversized 20 wheels. I traded my 2008 Toyota Tundra in on my F150 after viewing the video that Ford produced touting the engineering that went into this truck, the torque it produced, and all this with great fuel economy. Right now Im trying to find a dealership that will buy my F150 so I can go back to a Tundra!
