I’ve always hated my lawn mower. But once I started using Marvel Mystery Oil in a lawn mower, and putting synthetic 10w-30 oil in the crankcase, I’ve been much happier. It makes me feel like I discovered one of the secrets of the universe.
While you’re at it, check the air filter. You’re supposed to change that every year, at least. The combination of a fresh air filter, Marvel Mystery Oil, and synthetic oil gives me easier starts and smoother running.
