can i put motor oil in my lawn mower?
<answer> Yes <context> Type of Oil. You usually have no need to buy high-priced oil for your mower. SAE 30 motor oil is commonly recommended for use in a lawn mower engine, but the safest best is to use the type of oil your lawn mower manufacturer recommends.emoving the Gas and Spark Plug. Before you change the lawn mower's oil, the first steps you should take are emptying all the gasoline from the mower's fuel tank and disconnecting the spark plug wire. When you change the oil, you usually tilt the mower to one side, allowing the oil to drain out.
