Don't turn on the AC if you can help it-- it's like losing an entire cylinder from your engine! That's what many people claim, anyway. And so, for years, the eco-conscious driver have rolled down their windows on hot days, forsaking the air conditioner.
But is that really better? What about the effects of wind drag? If you're driving at any speed, having your windows open makes your car an open parachute, ruining your aerodynamics.
Which is really better?
The Mythbusters conducted a test comparing vehicles at 45mph, each with precisely 5 gallons in the tank. At those speeds, the car with its windows rolled down drove for 15 miles more than the car with the AC on.
There you have it, keep your windows rolled down and enjoy that fresh, green mountain air while it lasts. And come visit Earthycars. A fresh tune-up with our service center is another great way to improve fuel economy.
