Oil coming out of the exhaust with excessive smoke on a lawn mower typically indicates a few possible issues. It could be due to an overfilled oil reservoir, causing excess oil to be pushed into the combustion chamber. Additionally, worn piston rings or valve seals can allow oil to leak into the combustion area, leading to smoke. Lastly, using the wrong type of oil or a malfunctioning carburetor might also contribute to this problem.
