Using 5w-30 oil in a lawn mower can be acceptable, especially in colder temperatures, as it flows better than thicker oils during cold starts. However, it's vital to first check your lawn mower's manual. Manufacturers often specify the best type of oil to use based on the engine design. For most lawn mowers, SAE 30 is the standard recommended oil. If your manual states 5w-30 as an option, it's generally safe to use, especially for improving cold-weather starts without causing harm to the engine during the warmer season.
