My EB rolled around 7mpg towing my Travel trailer on a recent trip. About the same as my F350 with the V10. Now I understand my axle ratio might be hurting me there with the 3.31 as opposed to the 3.73 of the V10. The EB is undeniably more powerful and pulls harder in every respect. But at the same speeds the mileage difference is nonexistant. I really need to find a way to make this better. I can do the obvious by making sure I dont tow fresh water as I can get that on site or close by in most places. What else can I do? Is there really anything to be gained by running premium fuel? Enough to offset the .20 per gallon price difference? I dont want to do anything to effect the warranty so tuning is out. Would intake and exhaust make it too loud towing? Is there possibly a reflash of the ECU that could help if I complain about mileage? I dropped to 55 from 65 for awhile on the freeway and the instant read showed about the same mileage. There's very little flat ground on my route and I know this doesnt help. I am just looking to make those trips a little easier on the wallet. Do the roof mounted airfoils do anything at all to help towing mileage?

Now dont think I'm hating on the EB. In town and freeway mileage unloaded is light years ahead of my V10 which gets 10mpg freeway or city. Not to mention it's quieter and a damned sight quicker.

Get a tuner, you will increase power AND gain better fuel mileage. Just putting premium in will not see any gains.

Can you give us some more details on your travel trailer (width, length, weight etc).

I know 9-10mpg is about average for pulling decent sized loads.

You didn't say how heavy your TT is. I'm towing 6K plus dogs, wife and stuff in the bed, etc. here in Colorado. Recently left Buena Vista (8,200') hit I70 over the Continental Divide (12,000') down to Loveland (6,300') and back up to Estes Park (8,100). My '13 FX4 Ecoboost averaged just under 10 mpg driving 60-65. On less aggressive tows at altitude I can get 11 mpg.


I bet weight is probably your "problem." Sounds like you weren't hanging in the left lane at 75 mph.

If you want 10+ mpg towing you will be disappointed with anything other than a 3/4 ton diesel. The Eco loves fuel under load. Nothing wrong with that, per say. That's why its tows so well. It's just the nature of the beast.

If you are towing anything more than 4-5k lbs. I would recommend running premium fuel. Especially in the heat. There is a noticable difference when towing in power and in mileage. I tow a ski boat to the same lake using the same route regularly under the same conditions (hot, humid summer days in Georgia) and notice less downshifting on the same hills and improved mileage by about 2 mpg when towing. I run it exclusively now. To me its worth the extra $7.50 a tank

There is a reason ford recomends using premium when towing.

Premium, no ethanol fuel.

Slow down! Try to run 55-60 mph (trailer tires are only rated to 65mph).

Make sure TT is as level as possible when pulling.

Check air pressure on all tires. Put max psi in both.

Try to time redlights so that you don't have to completely stop.

Take full advantage of hills by coasting down the backside of them.

Did I mention slow down? Slowing down is the single biggest way to save gas.

Watch the instant mpg meter and learn from it.

My sweet spot is around 60mph and 1500rpm. You will probably need to lock out sixth gear.

Tow/haul mode will give you better mpg in most cases. It keeps the torque converter locked up until right before a downshift. However, it does hold a gear longer before up shifting. I sometimes toggle back and forth to force a higher gear.

I average 10.5-12.3mpg using the above techniques. Hauling the rig in my avatar.
