I notice quite a difference when we go on holidays to places at lower elevations,with my boat so obviously truck is gonna do the same.
I guess in a perfect world , i'd get 25mpg but for now i will quit complaining and enjoy my ECOBOOST. As for hemi,s getting 20 i find that one a little hard to believe and as for cylinder deactivation again i call BS. Think about it .... How often do you really think they shut down? Under normal driving ? Thats next to never gonna happen. Maybe on a roller dyno with zero resistance under perfect conditions. Likely the same place Ford got there 25mpg number?
