I have a 2020 RS and twice I almost ran out of gas by believing what the range was showing. I miss being able to reset the gallons used like what my Trailblazer had. It was pretty accurate knowing how many gallons I had left and knowing the miles per gallon, I could figure out easily how far I could go without running out of gas. I'll have to check one day how many miles I get with a tank of gas. Might way until warmer weather. When I first got my car, which was the end of August 2020, I was getting 22.5 miles to a gallon. It is now the end of December and 10,000 miles later, it has dropped to 19.5 m/gal. Anyone else have this experience?
