So, after extensive testing this summer I have come to the conclusion that running with the AC on cuts mileage in half and cuts power by at least half. This is especially apparent in temps above 85F. My poor gal seems to have no energy at all when i tromp on the skinny pedal with the AC on. Mileage it seems I get about 9mpg with AC and 14mpg without in the city. Highway is more like 13/18 with/without. Anyone else?
