The Coolest Way to Save Gas? Don't Be Such a Drag!

You've probably been told that you can save gas by turning off your air conditioning and rolling down your windows. No matter what, turning off the AC helps your gas mileage more than it hurts.  But it’s not so black and white when it comes to windows!  Cars are designed to slice through the air, so depending on your speed, rolling your windows down could slow you down. To avoid aerodynamic drag, keep ‘em rolled up if you’re traveling more than 40 MPH.
