Your dashboard's instrument cluster has a light on it that either says OIL or looks like an old fashioned oil can. What should you do if you see this light while you're driving? Stop the car! This is one warning light that isn't joking. The oil light comes on when your engine suffers a drop in oil pressure. Without oil pressure it can't lubricate itself, and the result is self-destruction, meaning you have to do some seriously expensive internal engine repairs.
