That's a lot less than we're getting. Click the fuelly link in my signature and you can see all our tanks.I mentioned earlier in this thread that I might try premium, even though I didn't expect any difference. I ran my last two tanks on 91 octane and there was zero difference from the several tanks before running 87 octane. No surprise there. I just had to try for myself.
After 2-3 initial tanks during road trips getting 21-22, my recent average is about 18.6 over the last several tanks. I'm only at around 3k miles, so I hope this gets a little better.
We've been getting great mileage from day one, but that's typical for all our vehicles. The one thing we've noticed on the Ascent is it's very thirsty the first three miles (around 18-20mpg), and then the mileage starts going up. By 10 miles it's somewhere around 22-23 and continues to go up from there. My wife's 3 mile commute to work each day comes in right around 20mpg, which drags our overall mileage down. The rest of our driving brings it up, so overall we're very happy with what we're getting. The dash readout has been right on compared to calculations at the pump.
When we first looked at the Ascent when the original 2019 came out, I test drove 5 that all returned 26-27mpg and one that only gave 20-21mpg. The oddball drove fine, but inexplicably had terrible mileage. They were all driven on my same 11 mile controlled test loop at 70mph. The 23 Ascent we bought gave 27mpg on that same loop, so I'm not surprised that's what we've been seeing on the highway, and of course less around town. I hope you're able to resolve the low mileage on yours.
I realize that a 70mph loop will return the best a car can expect to achieve, and that highway trips at higher speeds are going to drop that mileage lower, just like stop and go city driving will hurt your economy. I'm typically in the top 25% of drivers on fuelly, so I realize my driving style is on the conservative side.
