I have owned a 2011 ecoboost for 4 months now. I used to own a 2008 ranger, the ecoboost gets the same, if not better gas milage then the 4.0 l ranger. Someone decided to reverse into me causing the truck to be in the shop a couple days. I recieved a 2011 f150 with the 5 l V8 as a rental, the gas milage nor power were anywhere close to the ecoboost. I haved pulled over 6000 lbs with both trucks, and even when givin her lots ofgas, the ecoboost would get 18 l / 100km. V8 would get 32 l / 100km. Huge difference, considering the ecoboost pulled with ease as the V8 was always high revs using much more gas. Very happy, would never go fpr the V8.
