- Once the plug is loosened, allow the oil to drain completely into the pan.
4. Tighten the Drain Plug:
- Once the oil has stopped draining, tighten the drain plug back into place using your wrench or socket. Do not overtighten.
5. Dispose of the Used Oil Properly:
- Used engine oil is considered hazardous waste. Do not pour it down the drain or into the garbage.
- Check with your local waste disposal service or recycling center to find out how to dispose of used oil properly in your area. Some locations offer free oil recycling programs.
6. Refill with Fresh Oil:
- Once the drain plug is secure, you can refill your lawn mower with fresh oil.
- Check your owner’s manual for the recommended amount of oil to add.
- Use a funnel to pour the new oil into the oil fill cap, which is usually located on top of the engine.
- Allow the oil to settle for a few minutes before starting your mower.
Tips for Safe and Effective Oil Changes
- Warm Up Your Mower: Running your mower for a few minutes before draining the oil can help thin the oil and make it drain more efficiently.
- Check for Leaks: After tightening the drain plug, inspect the area for any signs of leaks. If you see any drips, tighten the plug further or replace it if necessary.
- Change Oil Regularly: The frequency of oil changes will vary depending on the type of mower and usage. Consult your owner’s manual for the recommended intervals.
Additional Considerations for Riding Mowers
- Drain Oil from the Transmission: Riding mowers often have separate oil reservoirs for the engine and transmission. You may need to drain and refill the transmission oil as well.
- Check the Air Filter: While you’re working on your mower, take this opportunity to inspect and clean or replace the air filter.
Common Problems and Solutions
- Drain Plug Stuck: If the drain plug is stuck, try using a larger wrench or socket. You can also try applying a small amount of penetrating oil to help loosen it.
- Oil Won’t Drain: If the oil doesn’t drain completely, make sure the drain plug is fully loosened and that there are no obstructions in the drain hole.
- Oil Level Too High: If you overfill the oil reservoir, you may need to drain some of the excess oil.

FAQ
1. Why should I change the oil in my lawnmower?
Changing the oil in your lawnmower is crucial for its longevity and performance. As the oil circulates within the engine, it picks up wear particles and debris, gradually degrading its lubricating properties. Over time, this contaminated oil can cause friction, overheating, and even engine damage. Regular oil changes ensure your lawnmower runs smoothly, efficiently, and reliably for years to come.
Furthermore, fresh oil provides optimal lubrication, reducing wear and tear on internal components. This results in smoother operation, extended engine life, and better fuel efficiency. By investing a small amount of time and effort in regular oil changes, you can significantly prolong the lifespan of your lawnmower and avoid costly repairs down the line.
2. How often should I change the oil in my lawnmower?
The frequency of oil changes depends on the type of lawnmower and its usage. For most gasoline-powered mowers, it is recommended to change the oil every 25 hours of operation or once a year, whichever comes first. However, for mowers used infrequently or in dusty environments, it’s best to change the oil every 12-15 hours or even more frequently. Refer to your lawnmower’s owner’s manual for specific recommendations and adapt the interval based on your usage patterns.
Always check the oil level before each use and top it off if needed. Regularly inspecting the oil can help you identify potential issues early on, such as excessive oil consumption or contamination, allowing you to address them promptly.
