They tell me they are getting 11 with a trailer.......I sure hope there is something true about the break in period before gas mileage gets better or I will be regretting not going through with the deal on the FORD w/ECCOBOOST. Thanks for the input on your truck.
The Eco-boost isn't getting anything anywhere near what Ford is claiming. A friend has one and he's regretting shelling out the money for 15mpg. Sure he's got more power then my 4.8, but we tow the same thing, and I paid close to $15,000 less. And those turbos are going to be a fortune to repair when they go.
