Getting very poor MPG on my 2019 Ford Expedition XLT

[cekkk]

Iput this on my Lincoln. Takes five or ten minutes.

My 2017 Platinum did the same thing right at 100K. Several people told me it was the mass air flow sensor, I cleande it with minimal results. Was starting to believe folks that told me my turbos were failing. Just on a whim I picked up a bottle of Lucas Oil fuel system treatment. (I have no affiliation with Lucas and have never believed in additives and miracle cures). In one tank of gas I went from averaging 13 mpg to 19. Now I add a bottle every 3-4 tanks and still am in the 18-19 range. Not saying it will cure your vehicle, but for $10 it’s worth a shot. FYI when my EXP was new I got about 20 hwy, and 17 in “town”. I’ve pulled my 4500 pound boat about 30K, and mileage usually would drop to about 14. It was hitting 10 before the fuel treatment, and returned to the 13.5- 14 range after. I now have 111K and mileage seems to be holding up.

I have a 2022 Expedition Platinum and right now I'm averaging 23.5 MPG. I drive a mix of city and suburban roads. A lot of mileage depends on your driving habits. Jack rabbit stars doesn't help. I don't wait until the last minute to brake for a light or stop sign. Many times I can coast to the stop which helps. A lot of stop and go driving will kill your gas mileage.

What city do you drive in?

My 2019 Expedition in normal mode gets 17 to 18mpg city. However, we are very flat here.
My highway mileage from Florida to Georgia, doing 70mph, gets 25-28mpg using Eco mode.
If you have access to Forscan, reset your tcm and pcm settings. My mileage was weak when I first got mine. After resetting, the vehicle relearned my driving habits.

I bought 2 expeditions in the same week. Both used. A 2019 with 125,000 and a 2020 with 87,000. I do city driving everyday. I have been averaging 17.4 in the first 3 gas tank fills. Back story is I have a 2011 f150 ecoboost supercrew which I make 14.9 at the lowest and about 15.9 on the same trip over the last 2 years. So I love the boost and not shy about about giving it the gas when I want to go. I love the power. So long story short is I can drive the expeditions as hard as I want and cannot do under 16.5. I really do not know the service history on the expeditions, because you know nothing other than oil changes and piddly stuff is recorded in carfax.
