2022 Expedition XLT 13.5 mpg

Hello we recently purchased a clean 22 XLT, Max Tow pkg. with about 10,000 miles on it. We did a leveling kit and are running 275/60/20 tires. This vehicle has averaged around 13.5 mpg for the past 3k miles and I am wondering why it doesn’t do any better? As far as hwy miles we have only driven it up to the mountains and back with lots of gas guzzling hill climbs. Tomorrow we will be driving to Topeka KS so we will be able to get a better idea of mpg between fuel stops. How much should I expect on our long drives across Texas and Oklahoma at 75mph? Does Eco mode make much of a difference? My 2020 F150 with Whipple Stage 2 kit and 285/75/17 does much better than this truck, around 16 mpg around town if I drive light footed. Anyways I hope to check in this week with some real time data. Will run the tires at 40 psi all around. They are FALKEN wild peak at4w load range D.

‘20 XLT HD Tow, Just drove from Md to Ohio over App Mts, in/around town for long weekend, and back. 70-75mph on hwy. 22.6mpg. With a full vacation load and pulling my boat 600mi Md to KY at 70mph I get 14.5mpg. You have something wrong somewhere.

When I hear what some of you are getting for gas mileage, it makes me think about actually getting a new Expedition to replace my 2003 Expedition FX4 that only has 116,000 miles on it and gets about 13 to 13.5 mpg. But, since I work from home, why make payments when this lifted 4X4 takes me anyplace I want to go? I don't know if it's still the case or not, but my '03 weighs in at just under 3 tons. That's part of why driving in the city with big, heavy off-road tires kills your mileage.

You lifted the vehicle so it sucks more wind/air, its never going to get good milage on the highway like that. Ford lowered it down for a reason, not just so it looks gross....

I have HD Tow with the 3.73 gearing and get about 12-13 (alot of stop and go) city driving with (ASS) OFF. I get about 20-22 (highway) somewhat level roads

I have HD Tow on my 2019, and have seen anywhere from 9 to 15 MPG towing, typically 12-13, and 12-22 open highway long distances, according to the dashboard computer. when I've crosschecked it manually on random tankfuls, its been pretty close, within the tolerances of how much gas might be in that 'full' tank. I've also cross checked the trip meters mileage readings against google maps, again darn close. Other than mountains, the single biggest factor is speed. oh, premium gas doesn't seem to change a thing

Thanks for all of the replies!

*when purchasing the tires I was aware of the extra weight but was still somehow hoping to do a little better around town. But not a big deal, we are happy with it. We took it up to the mountains on a sharp rocky road and we were glad to have solid tires.

* My F-150 has the max tow so it does have the 3.73. I think the Whipple tune and 91 octane helps the mpg.

*Today we did 17 mpg @ 80mph from Holbrook AZ to Tucumcari NM according to the computer. I was dumb and forgot to manually calculate. I will pay attention tomorrow and post that data.

* I am also interested to see difference in mpg between 70 mph and 80 mph.

*Are the factory tunes optimized for mpg or are their after market tunes that might help? The tunes more or less just change shift points and timing or is their more? Could a tune optimized for this larger tire size help? What about better air intake?

*Also if all factors remained the same what do we think the difference in mpg might be between 3.31 and 3.73 axles?

Overall I realize the expedition is heavy and the wheels/tires are heavy. Considering the hp these motors produce and how good these drive I feel like I should be pretty happy with m current mpg. Thanks again for the input!

fuel efficiency tends to go down exponentially with speed. cruising at a steady speed for long distances on a level freeway, the lowest speed that it will stay in top gear will probably give you the best efficiency. 55-60 is way more efficient than 65-70 which is way more efficient than 75-80.

My best highway mileage is in the 55-65mph range. We live in an area with many roads that are still in this range for speed limit, lot of two way roads here in NW Minnesota.

The trips I take have a considerable part of the drive in 80mph speed limits, so I am usually going 85ish with a Velocirax and at least a couple bikes and with that combo I am still usually getting 18-20ish. If there is any headwind at all that number drops pretty good. Not having the rack on usually gets me an additional 1-2mpg at those same speeds. Slower speeds def net better results. It also seems like everywhere in Utah is uphill both ways. I went to sunrise, AZ a bit ago and with some slower speed limits in AZ and some long flat stretches, I got a 22mpg with the bikes on the back.

We get 18.5 around town and easily get 22 on the freeway even at 70-75mph. My experience on many vehicles is that what you lose going up mountains you get back coming down. But as others have said, lots of variables, but you know that.
