Does anyone know the trick for resetting the milage until empty. I will drive until and get down to about 20 estimated miles left until empty. But when I fill up, I only can squeeze in 17 gallons. I would like to get the estimated miles left accurate to represent the 21-gallon capacity. My MPG is around 20.2 when I filled up. I have 2000 miles so far and I thought it might have fixed itself but not yet…
