How Much Does AC affect Mileage?
So I drove to Ohio from Montana & back and averaged 37 MPG in the Civic that's rated 34 MPG hwy. I stayed at around 70 Max, 65 when the law. My tanks ranged from 41.2 to 34.6 MPG. Question...How much does the AC kill mileage?? I'm guessing a 8-10% hit (3-4 mpg to me), what is the general rule of thumb on this? I had to have it on half the time cause it was freaken hot out. My fuel log showed this difference.
