Did you ever notice just how impressive NASCAR mechanics are when they take off the spark plugs from racecars? Apparently, they can do this so quickly because they keep a can of WD-40 handy. It is the secret to avoiding wasting even an extra second, which can make a world of difference to get their drivers on the road again. Of course, this trick will also work on your regular car.
