Engine oil forms a lubricating film inside the lawn mower’s engine, reducing friction and wear between its components. Additionally, it cleans the internal parts of the engine. However, the oil gradually loses its lubricating properties over time, causing parts to wear down and increasing the risk of rust and corrosion. Therefore, it’s necessary to master the guide on how to change oil in lawn mowers regularly.
Guide To Change Oil In Lawn Mower
Preparation
- Place the lawn mower on a flat surface, as it facilitates easier draining of the old oil and measurement of the new oil to be added.
- Start the engine to warm it up, allowing the engine and oil to reach the optimal temperature for smoother oil flow and easier draining of the old oil.
- Disconnect the power source to prevent any accidental starting and ensure safety.
Steps To Change Oil In Lawn Mower
- Clean
Remove all dirt and debris around the oil cap to prevent any debris from entering the crankcase.
- Prepare for Draining
1) Ensure the oil tank cap is securely fastened.
2) Place a large container (such as an oil pan) under the drain hole.
- Drain the Oil
Remove the drain bolt and then the oil cap. Tilt the lawnmower towards the oil fill hole with the oil side down to drain the oil. Collect the drained oil into the container. Make sure no gasket from the drain bolt is misplaced and no components are dirtied. If your lawnmower deck has a drain plug, drain the oil from the bottom. After draining, replace the drain plug.
- Reinstall the Drain Bolt
Fit the gasket and drain bolt, then tighten the drain bolt to prevent oil leakage. Completely wipe off any oil from the bolt and equipment using a cloth.
- Refill with New Oil
Set the engine level and gradually pour in new oil (appropriate type) until it reaches the upper limit mark. Wait for two minutes and then check the oil level following the manual’s instructions. Replace the oil dipstick when finished.
- Tighten the Oil Cap
After refilling, firmly tighten the oil cap to prevent any leakage. Loose oil caps may cause oil leaks.
- Reconnect the Spark Plug Wire
If you used the tilting method, reconnect the spark plug wire and refill the engine with gasoline. If you drained from the bottom, reconnecting the spark plug wire is not necessary.

How Often To Change Lawn Mower Oil?
After the first 5 hours of operation, you should change the oil in your new lawnmower. Thus, oil changes should occur every 10-15 hours of use. It’s essential to consider the type of oil recommended in the engine manual. If your lawnmower operates frequently in harsh conditions like rough terrain or damp grass, it may require more frequent oil changes. Even unused oil can degrade over time, so regular checks and changes are advised, ideally every 6 months.
How To Dispose Of Lawn Mower Oil?
Improper disposal of lawn mower oil can have environmental consequences, so never pour waste oil into drains, ditches, or soil. Consult local environmental agencies or waste management centers for proper disposal.
Timely repairs and replacements when outdoor power equipment malfunctions extend the lifespan of lawnmowers.
