Changing your lawn mower oil is a crucial maintenance task that helps keep the engine running smoothly and extends its lifespan. It's a relatively simple process you can do yourself with a few tools.
To change lawn mower oil, you typically need to warm up the engine slightly, position the mower appropriately, drain the old oil, replace the drain plug (or tilt it back), add new oil, and dispose of the old oil responsibly.
Steps to Change Your Lawn Mower Oil
Here are the general steps for changing the oil in your lawn mower, incorporating information from the referenced video:
-
Prepare the Mower:
- Run the mower for a few minutes to warm the oil slightly. Warm oil drains more easily.
- Turn off the engine and disconnect the spark plug wire to prevent accidental starting.
- Place a drain pan or container under the oil drain plug or under the side you will tilt the mower towards.
- As shown in the referenced video clip, it's recommended to position the mower so the air filter is pointing up. This helps prevent gasoline from flowing into the air cleaner during the draining process.
-
Drain the Old Oil:
- Locate the oil drain plug (usually underneath the engine) or prepare to tilt the mower if it drains from the fill tube.
- If there's a drain plug, loosen and remove it carefully, allowing the oil to drain into the pan.
- If draining via the fill tube (often the case for mowers without a drain plug), tilt the mower over the pan, making sure the side with the air filter is up as mentioned in the reference.
- Remove the dipstick to allow air in, which helps the oil drain faster.
- Let all the oil drain out completely. This can take several minutes.
-
Add New Oil:
- Once the old oil has finished draining, if you removed a drain plug, clean and reinsert it, tightening it securely.
- Refer to your owner's manual for the correct type and amount of oil required for your specific lawn mower engine. Common types include SAE 30, 10W-30, or synthetic blends.
- Using a funnel, slowly pour the new oil into the oil fill tube (where the dipstick was removed).
- Add slightly less than the recommended amount initially.
- Check the oil level using the dipstick. Insert the dipstick fully (or rest it on top, depending on your mower model), remove it, and check the level between the "Add" and "Full" marks.
- Add small amounts of oil as needed, rechecking the level each time, until it reaches the "Full" mark. Avoid overfilling.
-
Dispose of Old Oil:
- Old engine oil is a hazardous waste and must be disposed of properly.
- Take the oil to a recycling center or an automotive parts store that accepts used oil. Never pour it down drains or onto the ground.
Essential Tools & Supplies
Changing lawn mower oil requires a few basic items:
- New engine oil (correct type and amount for your mower)
- Wrench or socket set (if you have a drain plug)
- Oil drain pan
- Funnel
- Rags or paper towels
- Gloves (optional)
- Container to transport old oil for recycling
Performing this maintenance regularly, typically once per mowing season or after a certain number of hours of use (check your owner's manual), will help ensure your mower starts easily and runs efficiently.
