I have a 15 Expedition XL 4x4 and have averaged 17.8 mpg over the 30,000 I've driven it. Cruise set 80 mph freeway driving I'm getting anywhere from 21-23 mpg. 3.5 V6.

Had a 2013 Supercrew with the eco boost. Got about 18mpg on the highway. 14.5-15 around town. Only thing I didn’t like was listening to the electric fan run during the summer. If it was over 95 degrees outside the fan would scream while the AC was on.

I think our first was a 2016 crew cab sort bed 2.7 bone stock and the current one we have is an 18, same truck configuration also 2.7 I believe the current truck is giving 19-20 mixed driving and 22-23 hwy. The 18 has the 10 spd trans, I personally preferred the previous trans. Reasons being that it seems a bit confused on low speed shifts with the 2018 10 spd.
We love the trucks tho, both have been fantastic. I just took it off the hoist, did an oil change. I like the topside oil filters. 6 qts 5w30 full synth
Something clever here.

I have a 2014 EB that I bought new. Now has 64K miles. Up to 50 K it averaged about 17.5. and then it started dropping of down to 13.5
. According to ford service the problem is carbon build up on the intake port and the intake valve. They recommended a flush/cleaner which helped some but it is now only getting 14-15. Ford wanted $4000 to pull the heads and clean valves, ports, etc.
I talked with mechanic friend and we are going to give it another flush. If that doesn't work he said we can pull the intake manifold and reach everything that needs to be cleaned.
If I had to do it again, I wouldn't

lefty C They have hopefully fixed that issue with the redesign in 2017 in the generation 2 Ecoboost. They now spray fuel on the valves with another injector to keep them clean.

I have a 2017 and my hunting buddy buys a new one every year. I am in them a lot. With factory Wranglers mine was an honest 21-22 on the highway. I put some load range E, one size bigger Falkens and it dropped to 18-19 on the highway. I am going to put stock tires back on it now that winter is over. I get about 16-17 in town.
My hunting partner has 4 F150s with 2.7s in them. We took one bear hunting last year. I pulled over and got out and lifted the hood I was so impressed. I had to see for my self that it was really a 2.7 liter. I drove most of the trip- 25-26 on that bear hunt. No idea what he gets in town as his employees drive them so he doesn't see the mileage.
My computer mileage is spot on with hand calculating it. Why anyone would buy a 5.0 is beyond me. Ford only makes it to appease the few old-timers that can't wrap their head around twin-turbo, variable valve timing technology.
Are there things I don't like? Yes, you have to have the truck on a lift to change the oil, You can hear the fan. Other than that, I can't think of anything.
