According to owners, 5.0L has average MPG range of 15-23 & 3.5L EB appears to get 16-25. These wide MPG ranges seem to persist even within similar models of trucks. Why the wide MPG range reported by 5.0L & 3.5L EB owners?
My friend has a Lariat 5.5' CC 5.0L with 3.55 gears. His truck's performance was awesome with average MPG 14.8 at 3000 miles. It's performance was enough to keep me from buying a dealer's Raptor that averaged 11.2 MPG over 1155 miles (Trip A).
Thought about buying 3.5L EB FX4, but buddy who is one of the top Texas Ford trucks salesman advised me to buy a 2011 5.0L with 3.73 gears. His customers 5.0L averaged 17-18 MPG & 3.5L EB 19-20 combined city-highway. Most drive 3.73 gears & get similar or better MPG than the 3.55. My Texas truck selling friend drives a Lariat CC 5.5' with 3.5L EB & 3.55 gears, 20/80% city/Hwy. He believes the EB performance is same in city, better on Hwy & he only gets 18.5 MPG. Performance pulling trailer is a lot better, but mileage sucks compared to his old 5.0L. If Ford doesn't ecoboost the 4.6 or 5.0 in next 1-2 years, he plans on going back to 5.0L with 3.73 gears.
Over 1st 4500 miles, my FX4 6.5' CC (5.0L, 3.73 gears) carrying average of 350# extra load, averaged 18.5 MPG doing 80/20% city/Hwy at 75-80 MPH Hwy. Added 150# Frontier brush guard & next 2000 miles without the extra 350# in the bed, 50/50% city/Hwy averaged 17.8 MPG. This is 3 MPG better than my friend's 5.0L 5.5' CC Lariat with 3.55 gears, doing the same 50/50% city/Hwy driving with same factory tires & no brush guard.
My FX4 is about to get 35x12.5x17. I will keep folks posted on the fit & if there is any significant change in MPG after correcting for speedo.
