Oil on a lawn mower spark plug can be caused by a few reasons, such as a worn piston ring or valve seal that allows oil to leak into the combustion chamber. This can lead to poor engine performance and difficulty starting the mower. Regular maintenance and checking for leaks can help prevent this issue.
