Not trying to be a dick here or derail post, but that's almost the same mileage I get in my 16 5.0 SCrew. With probably 60% city driving.

Unless there's a large price/feature difference, personally I'd go with the best bang for your buck, because as far as I can tell (from post gleaning, no actual experience) the 2.7EB, 3.5EB and 5.0 are all very comparable in capacity, capability and mileage.

The 2.7 has some real get up and go.... mine has last 942 miles so far, so I am happy.

Can't disagree with you more. Had my 2.7 for 2 years now, 68k, and I've been driving a 5.0 rental for over a week now. It's a 2017, XLT SuperCrew 4x4 5.5 box with 36 gal tank with 7000km on it. I've already been discussing this in another thread. While it feels "smoother", it doesn't have the same pickup as the 2.7 at all. I find the 5.0 to be slower, needs more gas to get going and needs much higher RPM.

Not sure why pierce is getting that low of mileage on a 2.7 but I consistently get 25+ MPG with 70% highway. The 5.0 I've been driving has been driven exactly the same, my same route to work, groceries and errands etc, and I'm getting 15-16 MPG in the 5.0.

2015 2.7L 4x4, one year old, 22k miles. No drivetrain issues. I average 18.73 MPG (hand calculated) lifetime, probably about 60% city and lots of hills in my commute.

For MPG, i get about 18-20 in town depending on how lead my foot gets.

For highway driving, I just drove to reno and back, ~500 miles, and averaged 24.3mpg

I'm in Utah as well. Just about 20k miles on the first production year (2015) 2.7L. No issues to date, and the thing pulls better than my previous V8. It's a pleasure to merge onto freeways, and just cruises nicely at all legal HWY speeds (and some not legal ). It would be a nice jump from the 3.7L.

As a 2016 5.0, 4x4, SC, 3.55 owner, I have to agree with this. I have had the truck for a little over 6 months now. Most of my driving is city driving and I hover right around 15-15.5 mpg. I made two highway trips a couple of months ago from Biloxi to Mobile. On both trips I filled up before leaving and filled up after arriving back in town. Hand calculated 16.7 mpg on one trip and 16.8 on the other. This was driving with the cruise control at 70mph each time. Also a very flat drive. No where near the 21 the sticker says. Quite disappointing. I have a 2in level and 33in BFG KO2's. Those 2 things should not affect mpg that much.

Slow to 55 and your MPG will increase noticeably, but your level and tires give you a 2 or 3 MPG hit.

The best price nearby for me is a pretty loaded 5.0. Gorgeous red and very well cared for. I agree to an extent. On paper I think the 3 engines are pretty similar. I follow a lot of F-150 owners on YouTube, and 5.0 owners seem to be getting mpg in the high teens with the stock tires. But from my research it seems that the 2 turboed engines are a lot more nimble, which would be a nice change from my current 3.7, which I bet drives more like the V8 (you need a little more pedal to get it going).

I'm sure it would be a nice jump. The 2.7 is the only engine I've never driven. I've had a couple goes with both the 5.0 and the 3.5 Eco. The 5.0 seems great when I drive it, and I tell myself I'll never need more "umph", but that's what I thought when I first drove the 3.7 too, and here I am not even a year later longing for something more.

When I put 33's on my truck I took about a 2 mpg hit. Then another 1 mpg when I leveled it out (not sure why, I didn't think this would have an effect). And this is all consistently hand calculated on every tank. There were pretty obvious effects on my gas mileage.

I am averaging 20.4 mpg and have 32000km on mine (~20000 miles).

Replaced all cam phasers on passenger side.
2 oil pan leaks and possibly a third.

Had truck about 20 months now.
