I will reset mine before going on a road trip. Each time, I consistantly get 21-22mpg on the highway. This is averaging 65mph on mostly flat roads. I see 17-18 in the city and never any lower
I could see 21-22 on flat roads... To bad those don't exist in my neck of the woods. Oh, but that's why I also have a motorcycle - to enjoy the lack of flat (and straight) roads!
