A worn drain plug can show up as oil spotting under the parked car, a rounded hex head, damaged threads or a plug that has gone missing. Oil drips can have other sources, so at an oil change, with the engine off and cool, look over the old plug's head, threads and gasket and compare its thread to M22-1.50 before you assume the plug is the cause.
