Finally got to take my(new to me) 06 EX AWD, auto trans, on a Central Georgia shakedown weekend trip. Got 25.4mpg going there and 25.6mpg coming back partially in the rain. It was mostly 2 lane highway trying to keep close to 60mph up and down hills so i didnt use the cruise. Speedo is almost dead on with the gps speed. Is this mpg good, bad or average?
