I have a 2013 screw 3.5 ecoboost 3.73 max tow, stock tire size. I just got home from a trip from Washington state to Utah and back. I pulled a 4000 lb trailer. The truck ran great the entire trip, it actually ran smoother than it ever has. The only problem is that I averaged 7.7 MPG. I ran at 65 MPH and yes it seemed to be uphill both ways, but I was hoping for better gas mileage. Is this normal?

They tow great but they are thirsty. I get 10-11 pulling my UTV on an open trailer. My previous 6.7 Powestroke would get 13-14 pulling the exact same setup on the exact same route. I'm guessing you have a large profile on that trailer that creates drag. I've pulled heavier trailers that were more aerodynamic and got better mileage. Bottom line is that you shouldn't be worried.

Ecoboosts like fuel, especially when towing. Lots to account. Fuel octane, wind, tire pressure, air temp, humidity, etc etc.

When you're in boost, you'll suck it down.

Thanks for the replies. The truck pulled great and I usually only go a couple hours from home so I can live with the gas mileage.

I get 11mpg pulling my R-Pod through Alaska at 65mph'ish. Sucks, but I don't have any trouble going up hill.

TFW you can pull a trailer through a mountain pass effortlessly but get gas engine mileage.

OP if you want diesel engine mpgs towing, you should have got a diesel.

I agree the mpgs drop hard but the eco tows better than a NA v8 hands down!

Thats about as good as it gets. I get the same with my TT. Pulled mine a couple weeks ago to utah and back did about 7-8 mpgs.

I get about 10ish pulling my 3500lb ChampioN bass boat all over Texas but I can't even tell its back there. I just got my ecoboost about a month ago and love it compared to the 2005 F150 with a 4.6L v8 I had for 12 years.

I pull a 9200# total weight travel trailer. Against the wind i get 10mpg's and with the wind I get 12mpg's. Im in NW Ohio so this is on flat land. My signature shows my add-ons which I think help alot compared the stock guys.
