I stopped a couple of days ago at the gas station. I had less than half a tank and the trip screen on the dash was showing 15 mpg. I filled it up, the rest of the way with non-ethanol gas. Back on the rode hom the mpg on the dash went to 18, than 21, than 22.1. I don't know the accuracy of the on-board computation but I was very suprised. Does anyone have a similar finding. Mine is a 2019 with less than 10k miles.
