I had recently purchased a boat off of eBay and made the trip from WI to AL this weekend. It was about a 17 hr ride one way. I just thought some people would like to see REAL world empty and towing interstate gas mileage for the EcoBoost.

Truck: 2011 F-150 Crew Cab/4x4/Eco/3.31 axle/Tow rating of 8200#. The truck had 6003 miles before I left Thursday evening and now has 8162 miles. There were three people with bags for 2 nights worth of clothes, snacks, plenty of tools, jacks, spare tire, etc.

Boat: 2000 Baja 25 Outlaw w/ 502 Mag MPI. The weight of the boat/motor/trailer/gear/gas is about 7000#.

No trailer gas mileage:
70 MPH: 19.5-20 MPG
75 MPH: 17.8-18.3 MPG
80 MPH: 15.5-16 MPG

Hooked up to the boat on the way back to WI:
I don't ever pull a large load on cruise unless on flat ground. From Central AL to Southern IL was very hilly, so no cruise was used. During that stretch going anywhere from 65-75 MPH I got a consistent 11-11.5 MPG.

Once I was able to get on flat ground, I was getting 14.3 MPG at one point with cruise set on 65 MPH.

I just wanted to let everyone know that I was VERY impressed with this truck. The turbos work amazing when on tow/haul going down hills, gotta love the muffled jake brake sound! I had no problem keeping speed, or even gaining speed going up the biggest hills (6*+). This engine is really the little engine that can do everything!

 

AND with 3.31 gears?? Not bad. Imagine how much better that experience would be with 3.73 or 4.10's!!!

 

My dad and I were wondering the same thing. His EcoBoost has 3.73s.

3.31s were PLENTY for my trip. I never had the pedal all the way to the floor, except for when I was going up a hill and wanted to see how it would accelerate ha.

 

Your towing MPG is great, but ^^ i would expect more on the highway w/ the 3.31's. I get 17 doing 85 (speed limit is 75 in between dallas and houston) w/ 3.73's

 

I was thinking the same thing. I did check the weather on my phone while on the road and what do you know.. 10-15 mph S wind. That didn't help me out any.

 

Nice looking boat! Thanks for the info!

 

The wind will kill the mpg big time.

 

that's really impressive. and also a sick looking boat.

were your numbers off the truck's display or did you hand-calculate them at fill up?

 

I bought a 2012 SCREW XLT on the road w/3.55 gears, had to two the other car home on a U-Haul trailer. Trailer was 2200#, car was about 3500# for a combined tow weight 57-5800#. From Ohio to Wisconsin got 13.8MPG measured, meaning not off the fuel econ. page.

 

I quit hand calculating a long time ago! The computer on mine is always withing .1 MPG, so there is no need for hand calculations. I think I may have got an accurate one

I am very impressed with everything about these trucks. The awesome towing fuel economy is just a bonus!

 

my wife's escape reads about a mile higher than hand calculated

 

The computer on mine has been dead on. I think they have improved how they calculate. I still keep the spread sheet and as long as I don't top off, it is the same.

 

That's like saying you have plenty of money or plenty of horse power

 

One can never have enough of anything!

 

and that right there my friend is how the mormon religion came about
