Fresh oil circulates through the engine, carrying away heat and metal shavings while keeping internal components clean and cool. This ensures a proper seal and makes future removal easier.
Lawn Mower Oil Change Safety First Steps
Allow the oil to drain completely until the flow stops, as residual oil left in the pan will mix with the fresh oil and dilute its additives. Tighten the filter by hand, turning it snugly against the engine; overtightening can make the next change difficult and potentially damage the mounting surface.
