I recently purchased a cheap, high mile, manual 2005 Civic Hybrid that I've been bringing back to life. I got the check engine lights and IMA light taken care of and auto-stop is back. It's been running great and mpgs have jumped up considerably.

One issue I've noticed is that the AC absolutely kills my mileage. I can generally achieve +60mpg on my daily work commute without the AC. Meanwhile it's difficult to even hit 40mpg with the AC on. I know air conditioning is going to eat mileage, but that seems incredibly excessive.

Is this consistent with what others are seeing or is there something i should take a look at? I realize "turn the ac off" is going to be the popular answer, but it's really not an option during the summer driving to work in South Florida.
