Step 2: Locate the Oil Drain Plug
- Find the Oil Drain Plug: This is typically located on the bottom of the engine, usually with a hexagonal or square head. Consult your owner’s manual for the exact location on your specific mower model.
- Clean the Area: Use a rag to clean the area around the drain plug to prevent debris from falling into the pan.
Step 3: Drain the Old Oil
- Position the Oil Drain Pan: Place the oil drain pan beneath the oil drain plug, ensuring it is centered and securely positioned to catch all the drained oil.
- Loosen the Plug: Use your oil wrench to loosen the oil drain plug. Turn it counter-clockwise until the oil starts to flow.
- Fully Remove the Plug: Carefully remove the drain plug completely and let the oil drain completely into the pan.
Step 4: Replace the Oil Drain Plug
- Clean the Plug: Wipe the oil drain plug with a rag to remove any dirt or debris.
- Reinstall the Plug: Carefully thread the plug back into the drain hole, ensuring it is seated properly. Tighten the plug using your wrench, but avoid overtightening, as it could damage the threads.
Step 5: Fill with New Oil
- Locate the Oil Fill Cap: The oil fill cap is usually located on the top of the engine, often marked with a “fill” or “oil” symbol.
- Remove the Fill Cap: Unscrew the oil fill cap and carefully remove it.
- Use the Funnel: Position the funnel in the fill opening and slowly pour the new oil into the engine.
- Check the Oil Level: Consult your owner’s manual for the correct oil capacity for your mower. Stop adding oil once the oil level reaches the full mark on the dipstick.
Step 6: Clean Up and Dispose of Old Oil
- Clean Up: Use rags or paper towels to clean up any oil spills, ensuring no oil is left on the ground.
- Dispose of Old Oil Properly: Old oil should never be poured down the drain. Dispose of it properly according to local regulations. In many areas, you can take it to a recycling center or a designated hazardous waste drop-off point.
Additional Tips for Changing Lawn Mower Oil
