A new article posted over at Yahoo Autos entitled Mechanics Set The Record Straight sheds some light on some commonly held auto misconceptions. Covered are questions such as:

-Do you need to warm your car before starting out in cold weather?
-Are all-season tires are as good as winter tires?
-Restarting your engine is harder on the engine and uses more fuel than idling?
-Is filling your tires with nitrogen is better than using plain air?

And a few more nuggets of information. Enjoy!
