Draining the Old Oil With the equipment ready and the mower secured, you can begin the draining process. Place the drain pan directly beneath the oil plug, ensuring it is positioned to catch the full volume of used oil.
How to Check Oil Level After Drain
Use the oil filter wrench to loosen the old filter, being prepared for some oil spillage, and then screw the new filter onto the engine by hand, tightening it according to the manufacturer’s recommendations, usually hand-tight plus a quarter turn. Fill the engine gradually, pausing periodically to check the dipstick level to avoid overfilling, which can lead to increased pressure and reduced performance.
Using the appropriate socket, carefully loosen the drain plug, turning it counterclockwise by hand once it is loose enough to avoid stripping. Fresh oil lubricates the engine, reduces friction, and carries away heat, but over time it becomes contaminated with combustion byproducts, metal shavings, and moisture.
