Just drive slower. I stuck to 60mph on the freeway and 50-55mph on the back roads. That seemed to do it. I refilled and now I think I'm in the 52-53mpg area. I forgot to check once I got home. My commute to work was 46.6mpg and my commute home was 61.?mpg. This time I kept it in Power Mode and drove 65mph most of the way and didn't do any rural road driving. On second thought, you are in the LA area so don't drive too slow. I don't want another dead homie.
