For comparison:
On summer gas (winter gas has less energy) I get between 15.5 and 16.5 mpg with my 2011 6.2L SCAB in 2WD. This is absolutely unfailing. It doesn't matter whether the driving is predominantly city or highway. Surprisingly, speed doesn't matter either. What does matter is my right foot. Drive sanely and the big V8 will produce surprisingly good gas mileage.
You guys who waited for a GEN2 because you thought that a V6 with twin blowers would produce markedly better fuel economy forgot something important:
Physics. It takes a certain amount of energy to move a heavy, big body, high profile vehicle down the road. To do the same work requires the expenditure of the same amount of energy. That energy will come from the fuel consumed and from nowhere else. Miracles do not happen between fill-ups. Physics happens.
First off you have to understand the MPG tests the government uses. The tests are done on a dyno in a VERY controlled environment and not by some heavy footed hooligan out on the roads. Every car manufacturer is pretty much put in a "best case scenario" setting and then they test the MPG.
Can the Gen2 get 17+ mpg on a flat highway with cruise control? Yes. Can it get 14+mpg in town if you stay out of the boost? Yes.
But if youre running around in sport mode all the time or staying in boost there is no chance in hell you will come close to Fords claimed MPGs.
Plenty of guys that have picked up their trucks so far are posting Fords claimed MPGs but they are being easy on the trucks during their break in period. Once you start getting into the boost say goodbye to any claimed MPG.
Why the F would they test for MPG on a Dino? It removes the wind resistance variable that most certainly can add or subtract from actual MPG. If this is true, then the EPA is dumber than I could have imagined.
My 2013 with a 5 star tune got 13.1 MPG, per the trucks display. I have a 17 with 1400 miles on it and it sits at 16.2 mpg. I have only reset it once. Driving the same habits with both trucks.
