The Oil Change: A Step-by-Step Guide
Now that you’ve gathered your supplies and taken necessary safety precautions, let’s move onto the actual oil change:
1. Locate the Oil Drain Plug:
- Refer to your lawnmower’s owner’s manual for the exact location of the drain plug.
- The drain plug is typically located on the bottom of the engine block.
2. Position the Mower on a Level Surface:
- This ensures the old oil drains completely.
- Place a piece of cardboard or a drop cloth beneath the drain plug to prevent spills.
3. Warm Up the Engine:
- Run the engine for a few minutes to help the oil flow more easily.
- This allows for more thorough draining and ensures all contaminants are flushed out.
4. Remove the Drain Plug:
- Using your wrench or socket, carefully loosen the drain plug.
- Once the plug is loose, you can remove it by hand.
5. Drain the Oil:
- Position the oil drain pan under the drain plug.
- Let the old oil drain completely into the pan.
- This may take a few minutes.
6. Replace the Drain Plug:
- Wipe the drain plug and the area around it with a clean rag to remove any dirt or debris.
- Tighten the drain plug securely.
7. Add New Oil:
- Locate the oil filler neck.
- This is typically located on the top of the engine.
- Use a funnel to pour the recommended amount of new oil into the filler neck.
- Check your owner’s manual for the correct oil type and quantity.
8. Check the Oil Level:
- Remove the dipstick and wipe it clean.
- Insert the dipstick fully and remove it again to check the oil level.
- The oil level should be between the “Full” and “Add” marks on the dipstick.
- Add more oil if necessary.
9. Clean Up:
- Dispose of the used oil properly.
- Never pour used oil down the drain or into the garbage.
- Many auto parts stores, recycling centers, and garages offer oil recycling services.
10. Start the Engine:
- Once the oil is added, start the engine and let it run for a few minutes.
- Check for any leaks.
- If you notice any leaks, stop the engine and retighten the drain plug.
Troubleshooting: Identifying Potential Issues
If you encounter any difficulties while changing the oil, here are some common issues and solutions:
- Difficulty removing the drain plug: The drain plug may be rusted or seized. Use a wrench or socket with a good grip and apply gentle pressure to loosen it. If it’s stuck, try using a penetrating oil like WD-40 to loosen it up.
- Oil leaking: If you notice oil leaking after tightening the drain plug, double-check that it’s securely tightened. You may also need to replace the drain plug washer if it’s damaged.
- Oil level too high: If the oil level is too high, you’ve added too much oil. Carefully remove the excess oil using a syringe or a small pump.
- Oil level too low: If the oil level is too low, add the recommended amount of oil to reach the “Full” mark.
Maintaining Your Lawn Mower for Longevity
Changing the oil is just one aspect of maintaining your lawnmower. Here are some other important tips to keep your mower in top shape:
- Regularly clean the air filter: A dirty air filter can restrict airflow and reduce engine performance.
- Replace spark plugs: Spark plugs wear down over time and need to be replaced regularly.
- Sharpen the blades: Sharp blades make for a clean cut and ensure your mower operates efficiently.
- Inspect and clean the fuel system: Ensure the fuel lines are clean and free of blockages.
- Store the mower properly: During the off-season, drain the fuel tank and store the mower in a dry, clean location.

Frequently Asked Questions
The frequency of oil changes depends on your lawn mower’s usage and the type of oil recommended by your manufacturer. Generally, you should change the oil after every 25 hours of operation or at least once a year if you use your mower less frequently. It’s crucial to check your owner’s manual for the recommended oil change intervals, as they may vary depending on your specific mower model.
Neglecting oil changes can lead to engine damage due to excessive wear and tear, so it’s essential to stick to the manufacturer’s recommendations. You’ll also want to consider factors like the age of the mower and the environmental conditions in which it’s used when determining the frequency of oil changes.
What Type Of Oil Should I Use?
The type of oil you use in your lawn mower is crucial for its performance and longevity. Refer to your owner’s manual for the specific type of oil recommended for your model. Typically, lawn mowers require a high-quality SAE 30 oil for optimal performance, especially in warm climates.
However, some newer models may require different types of oil, such as SAE 5W-30 or 10W-30, depending on the climate and operating conditions. Always choose a high-quality oil specifically designed for small engines to ensure proper lubrication and protection against wear and tear.
What Tools Do I Need To Change My Lawn Mower Oil?
Changing your lawn mower oil requires a few basic tools that are readily available at most hardware stores. Here’s what you’ll need:
- Oil drain pan: This is essential to catch the used oil for proper disposal.
- Oil wrench: This tool is used to loosen and tighten the oil drain plug.
- Funnel: This helps to safely pour new oil into the engine without spills.
- Rag: You’ll need a rag for cleaning up spills and wiping down surfaces.
- Gloves: Wearing gloves is recommended to protect your hands from dirt and oil.
Can I Use A Different Type Of Oil Than Recommended?
While it may be tempting to use a different type of oil than recommended by the manufacturer, it’s strongly discouraged. Different types of oil have different viscosities and properties, and using the wrong type can lead to engine damage.
The recommended oil is specifically formulated to provide optimal lubrication and protection for your mower’s engine, ensuring its long-term performance and efficiency. Using the incorrect oil can lead to increased wear and tear, reduced engine life, and potential engine failure.
What Should I Do With The Used Oil?
Properly disposing of used oil is important for environmental reasons. Never pour it down the drain or on the ground. You can recycle used oil by taking it to an automotive parts store or recycling center that accepts it.
Many communities have designated oil recycling programs where you can drop off your used oil for safe disposal. Check with your local municipality or waste management agency to find out where you can recycle your used oil.
How Do I Know If My Lawn Mower Needs An Oil Change?
Checking the oil level regularly is crucial to ensure your lawn mower’s optimal performance. You can usually find a dipstick attached to the engine that allows you to check the oil level.
If the oil level is low or the oil appears dark and gritty, it’s time for an oil change. If you notice any unusual noises coming from the engine, such as knocking or rattling, it could also indicate a lack of lubrication and the need for an oil change.
How Often Should I Check My Oil Level?
It’s a good practice to check your lawn mower’s oil level before each use. This helps to ensure that the engine has sufficient lubrication and prevents any damage caused by low oil levels.
It’s also a good idea to check the oil level after every few hours of operation, especially if you are mowing for extended periods or in hot weather. Regularly checking the oil level helps to prevent potential engine problems and ensures your mower runs smoothly for years to come.
