As you all probably know, southern California is having lots of heat. I found myself using my AC more and more last week. Normally, I will drive home with my windows up, with no AC or the fan. Like many, I’ve been under the impression that driving with the AC on will drop for MPG, however, this last week, with my AC running the entire 40.5 mile drive home, I’ve averaged by best MPG ever with my same driving habits. Can anyone explain why my MPG did not decrease with the AC blowing?

Thanks
