Just took my 7000lbs 31' camper for a test pull. I just used the tow/haul mode and got 6.6mpg on flat land at 65-70mph. That seemed a bit low to me. I got about 9 in my 2005 5.4. Anything I should do to get better mileage????

I run 60-65 and get 9-11 mpg. Mine is 7500# and 11'3" tall.

How many miles on your truck, what configuration, what gear, etc?

Its a fx4 super crew with 3200 miles on it. 3.73 gears. I was really hoping to get at least as good as my 2005.......Not to be I guess.

I read this article below and they also talk about the lower mpg for ecoboost. But they were towing up a grade also.

I recently towed a toy hauler to PA. weighing about 9k and got between 7-8 mpg. It towed and handled the trailer like a champ. The only thing I can think of as why the 5.4 got better mileage is because it could not go as fast? The guys trailer I was using said my lil V6 towed it better than his 2500 crewcab duramax.

The faster you go, the more wind resistance and the more into the boost you are. Drop your speed by 5mph and the mileage will improve a lot.

I pulled it with my 5.4 at the same speed with the bed loaded down with hunting gear. Don't get me wrong it pulled the camper great and had plenty of power. I was just expecting a little better MPG....

Also be sure you're on premium fuel (91 octane) - 87 octane is fine for the Ecoboost when you're empty, but it really needs to be on premium if you're going to put it to work.

Is the MPG gain worth the extra 20 cents a gallon??

20 cents a gallon is what, 6% more? so if your average towing mileage goes up over 7, its worth it (6.6*1.06).
