I got 26.5 per the odometer indicator and that was the highest I ever got. I thought I was supposed to do better on the highway and I typically set my cruise at 75. I need to test it the old fashioned way based on filling up my tank, calculate miles driven and then how much gas I can put back in the tank. It would be nice to see how close my MPG indicator is. I try to remember to reset it after each fillup or when getting on the highway. Be interested to know what others are getting.
