Not a significant difference. They did this on mythbusters. A lot more effective strategy of traveling efficiently is to just not make trips that aren't absolutely necessary.

Yeah if you have your windows open on the highway it hurts your ears. If you're driving about 60 mph it's a nice breeze.

On the highway, windows up is better. In the city, windows down.

In Phoenix, if you have a/c you use it! Have you ever been here in the summer?
