My opinion--your my vary.
I agree with above that diesels will get about 30% better fuel mileage but at a significantly higher initial cost along with generally higher fuel cost. Also, wind resistance is huge. With our Ford 6.7 diesel we got 11 mpg (within .5 mpg) for our square nose 6500 lb bumper pull, a 9400 lb fifth wheel and now a 12700 lb fifth wheel. My only explanation is that each one must have been more aerodynamic than the last one. 7 mpg would be disappointing, but gas engines do suck down the fuel. We got 8.5 gas pulling the bumper pull. Certainly a 250 with any engine would be a better towing experience (the 250 with a 6.2 only comes with a 6 speed) but at a repeat initial cost.) If OP only tows occasionally I would put up with the fuel cost which is probably small compared to the new truck cost right now with limited supply.

I can think of two things for the OP to try for improved mileage. Since the 2.7 engine is right at max towing capacity, definitely run in tow haul mode. Assuming it works the same as most other Ford tow haul modes it will at least raise the shift point RPMs keeping the engine from lugging with better fuel mileage. In addition it will be much easier on the transmission (read-> less transmission failure problems). Secondly, the 3.5 Eco-Boost recommends premium gas when towing, so I would guess the 2.7 is the same. That allows the engine to advance the timing for better efficiency. Only a couple of test runs would show if the mileage improved enough to pay for the premium cost.

I can't comment on the fuel economy, but 2.7 MPG is pretty bad for a <7000 lb trailer.

My choice would be a F250 with 7.3L gas.


THAT is funny, I don’t care who you are!

2.7EB engine, 7mpg was posted.

Use Tow/haul mode, downshifts earlier, up shifts later, staying in the power band. Stays out of the overdrives more. Also, lock out the upper 2-3 speeds, they are increasing overdrive speeds. Shooting for 65mph top speed should help. 60mph would be better for mpg when towing a massive wind block but traffic dependent. With any luck, you should be getting 9mpg or a fraction more.
Did you have a TT previously? Slower speed changes and not trying to get moving faster or more quickly makes a big difference.

Just curious why you wouldn't put it in tow mode while towing? On my tow vehicles, its like a completely different vehicle. 6,000 lbs isn't much on a diesel or a heavier duty truck but that's still a pretty good load. Tow haul will shift much tighter and will keep the engine in an optimum RPM range and won't let it bog.

OP - Are you running premium fuel? It's recommended for towing, as it will use extra fuel to prevent detonation.

Otherwise, the best thing is to slow down. Single digits should be expected towing with any gas motor, especially if you're trying to drive with regular car traffic.

You're having work the 2.7 harder than you would a larger V8 or even the 3.5EB.
IMO I'd jump to the 3.5EB before going F250 diesel or 3/4 ton gas. @6600 lbs an F150 is plenty of truck. The 3.5EB won't need to work near as hard so you should gain 2-3 mpg's.
The F250 7.3 will suck more gas when not towing and is a lot more $$$ than an F150 3.5EB. If you plan on going to something bigger then yes the F250 is a better decision.
FWIW anything over 60 mph is going to really cut into anyone's mpg's.

With the Eco's and towing, it's a lot about the amount of boost and rpms that will help. Running Premium does help when towing. You have to let the engine run at least a full tank so the computer can adjust for it, so just don't think you can toss a half tank of it and expect to see results. (I learned that myself)

Running on the flats, the turbos like more rpm's then boost. More boost, more gas. If you can monitor your boost psi, you will see that you will run more psi at lower rpms to maintain a given speed then running some 500 or more rpms higher. The engine will also run cooler too.

I'm getting an average of 10 mpg's towing my #7000 TT. I live in the NW and go over the passes to eastern WA all the time. Lots of flat, lots of grades, lots of downhill runs.

The smaller 2.7 puts out good power numbers, but it also needs more fuel to get to those numbers. Just like the 3.5.

I monitor my ODB2 sensors with a simple plug in and phone app. Gives me a ton of info that I didn't know before. Adjusting my driving and monitoring the temps, boost, etc, has made a big difference in towing my heavier TT.

Good luck! mitch

It is a EcoBoost, one or the other not both at the same time. When in Boost it is dumping fuel into the motor and being only 2.7L it is going to be in Boost the entire time you are towing.

if your truck is getting the job done, who cares about the towing MPG unless you're full timing and doing 30000 miles per year. The cost to upgrade to a F250 diesel will far outweigh some extra fuel.

I recently went from a '14 F150 with 3.5 EB to a '16 Ram 2500 CTD. Towing mpg went from 7-8 to 11-12 with the same camper (6.6K) and towing was much easier. Love the engine brake! Definitely use tow/haul, makes the entire experience better/safer, especially if you are in the mountains. But 250/2500 costs are an issue, so if towing flat and short, might stay with what you have, but if planning longer trips may want to upgrade.
Good Luck
