Filled up yesterday after highway and city driving. Added a little more after the automatic shutoff. Gas mileage was 19.8, displayed 305 miles to go. 800 miles on the 2025 GX OT.

Just did a long road trip with mostly interstate but a mix of mountain city driving as well. 1500 miles or so at 18.2 mpg.

I'm getting 19+ mpg more consistently. Often 20-20.7 MPG.

However - it depends a lot of how you drive (aggressive / braking / etc.) and this is also without doing Eco mode. Maybe this is an obvious caveat.

My suspicion is that if (1) you put it in Eco mode and (2) drove modestly with (3) more highway, and (4) little traffic, then you could get 20mpg fairly consistently.

GX 550; 2025.

footnote:
in Comfort mode it's awesome on hwy and hwy ramps, virtually no / no body roll as you get with sport and sport+. I also have no hood flutter and brakes are fine with only normal squeaks when there's been rain/moisture and haven't driven since rain. LOVE this truck.

in case some of you are hesitant to run the tank to "0" miles, I have run the last 3 full tanks down to zero miles showing. When I filled up and the auto pump stops I manually top off an average of 1.5 gallons more, and I'm adding ~19.2 gallons after it goes to "0". Like others have posted, it's safe to assume there are about 2 gallons remaining when you hit zero miles. Fuel Low and Refuel are what it shows on Cluster, but no audible.

Ok so I still drive like I have my BMW X5 and milage is pretty pathetic at about 12.5. Highway speeds when I'm on them is between 70-80 and then averages about 17.5. Here is the good news. In Sports plus setting if there is a 0-60 difference between my old BMW and my GX I sure can't tell. Once broken in, this engine is pretty damn quick especially considering it has the aerodynamics of squared off brick! I'd say 0-60 below 6 without braking is about right so call it 0-60 in 5.8-5.9.

I’m at about 6700mi on our 2024 Overtrail here in Colorado and seeing 17.3-17.8ish with mountain highway driving.

We recently did a 2400 mile road trip in our new 2025 overtrail, I busted most speed limits 10 to 15 mph when on open hwy. The most common mileage calculated during fill ups was 16.5 mpg. There was one stretch I was able to push 95 to 100 for over an hour, that tank yielded 15.5 MPG, the best fuel economy I calculated throughout the trip was 18.7 MPG.
I also noticed when I ran the tank down to zero miles I would only add 18 gallons of fuel, giving me the assumption I had 3 gallons in reserve each time. When we got back home I went ahead and ran it down to 30 miles past zero range and put in 20 gallons, indicating there was one gallon still remaining in the tank. Which would make sense considering it was mostly city driving and I tend to get about 15.5- 16 mpg driving locally.
Oh, and strictly regular unleaded throughout the whole time.

I just completed a 800 mile trip. Got 20.7 mpg driving up and down the Cascades at 70 mph. That was with my calculations. When I filled up, it showed 331 miles to go on the tank. I'm good with that.

That's similar to what we're consistently getting, 20.6 to 21.2 on our P+. Just getting ready to roll over 10k shortly.
