I’ve had my eco-boost for about seven weeks now. And I have to say, MPG on it isn’t good. Vehicle average since purchase is 15.1 mpg, bone stock I got 19 to 20.5 on the freeway. After the level and upsize to 34 inch tires, I am averaging about 16 to 18 (lucky on the 18) on the highway with an overall average of 13.7. Kinda missing my 3.0 powerstroke at the moment lol. Obviously the power of the truck is far better than the powerstroke, and you get pro power on board too, but it would be nice to at least get 18 on the highway consistently LOL.
