So I have a 2021 Chevy Tahoe LT. We have had it since November 2020 and we use it on 2WD. On the dashboard when I fill up with gas whether on a 1/4 or 1/2 tank i get different readings and we use 87/89. So what is the actual mpg we should be getting on this vehicle? I know 1 time it said like 314 but it has never gotten that high again. Can someone help with this?

The system takes your last average MPG to determine range. If you were on the highway and averaged 20 mpg you might get 500 shown. If you had been driving City at 12 mpg it would only show 300. My Numbers are just for reference.
