To change the oil in your lawn mower, first gather the necessary tools. Having everything ready ensures the process goes smoothly. This section will guide you on what you need before starting.
Required Equipment
Before you begin, collect these essential items:
- New Oil: Check your mower’s manual for the right type.
- Oil Filter: If your mower has one, replace it.
- Oil Pan: To catch the old oil.
- Funnel: Helps in pouring new oil without spills.

- Safety Goggles: Shield your eyes from oil splashes.
Wear old clothes you don’t mind getting dirty. Ensuring safety precautions will make the oil change process safer and cleaner.
Prepare The Lawn Mower
Before changing the oil, it is crucial to prepare your lawn mower properly. This step ensures safety and efficiency. Follow the steps below to get your lawn mower ready for an oil change.
Park On A Level Surface
First, make sure to park your lawn mower on a level surface. This is important because it prevents the mower from rolling. It also ensures that the oil drains completely. A garage floor or driveway works well. Avoid grassy or sloped areas.
Disconnect The Spark Plug
Next, disconnect the spark plug. This step is critical for your safety. It prevents the mower from starting accidentally. To do this:
- Locate the spark plug wire.
- Gently pull off the spark plug boot.
- Move the wire away from the spark plug.
By disconnecting the spark plug, you can safely proceed with the oil change.
Drain The Old Oil
Changing the oil in your lawn mower is vital. The first step is to drain the old oil. This ensures your mower runs smoothly and efficiently. Follow these simple steps to remove the old oil from your lawn mower.
Locate The Oil Drain Plug
First, find the oil drain plug on your lawn mower. It is usually located underneath the mower deck. You may need to tip the mower slightly to see it better. Make sure the mower is on a flat surface and the engine is cool.
Check your mower’s manual if you have trouble finding the plug. The manual usually has diagrams that can help.
Capture Old Oil
Place an oil pan or container under the drain plug. This will catch the old oil as it drains out. Use a wrench to loosen the drain plug. Turn it counterclockwise until the oil starts to flow.
Let the oil drain completely into the container. This might take a few minutes. Once the oil stops dripping, replace the drain plug. Make sure it is secure but do not over-tighten it.
Dispose of the old oil properly. Most auto parts stores accept used oil for recycling.

Remove The Oil Filter
Changing the oil in your lawn mower is essential for its performance. One key step in this process is removing the oil filter. This ensures that your lawn mower runs smoothly and efficiently. Follow these steps to remove the oil filter correctly.
Find The Oil Filter
First, locate the oil filter on your lawn mower. It is usually a cylindrical component attached to the engine. Check your mower’s manual if you need help finding it. Once found, make sure the mower is on a flat surface and the engine is cool.
Dispose Of The Old Filter
Before removing the old filter, place a container under it to catch any oil that may spill. Unscrew the filter by turning it counterclockwise. If it is too tight, use an oil filter wrench. Carefully remove the filter and let the remaining oil drain into the container.
Dispose of the old filter responsibly. Many auto parts stores and recycling centers accept used oil filters. Never throw it in the trash as it contains hazardous materials.
Install The New Oil Filter
Once you have drained the old oil from your lawn mower, it’s time to install the new oil filter. This step is crucial for maintaining engine performance and longevity. Follow these easy steps to ensure the new filter is installed correctly.
Lubricate The New Filter
Before installing, it’s important to lubricate the new filter. Apply a small amount of fresh oil to the rubber gasket on the top of the filter. This helps the filter to seal properly and prevents leaks.
Use your finger to spread the oil evenly. Be sure not to use too much oil. A thin layer is enough for the gasket to seal well.
Attach The New Filter
Screw the new filter onto the filter mount. Turn it clockwise by hand until it is snug. Do not use any tools to tighten it.
Hand-tightening ensures the filter is secure but not over-tightened. Over-tightening can damage the filter or the threads on the mount.
Check that the filter is correctly aligned and seated. This ensures there will be no leaks and the filter will work efficiently.
Add New Oil
After draining the old oil from your lawn mower, it’s time to add new oil. This step is crucial for ensuring your lawn mower runs smoothly and lasts longer. Let’s break down the process into simple, easy-to-follow steps.
Select Appropriate Oil
Choosing the right oil for your lawn mower is essential. Refer to your mower’s manual to find the recommended type and viscosity. Common types include SAE 30 for warmer temperatures and 10W-30 for varied temperatures.
Oil Type | Temperature Range |
---|---|
SAE 30 | Above 40°F (4°C) |
10W-30 | 0°F to 100°F (-18°C to 38°C) |
Ensure you have the right amount of oil. Overfilling or underfilling can damage the engine.
Pour In The New Oil
Find the oil fill cap on your lawn mower. Remove the cap and place a funnel into the opening. Slowly pour the new oil into the funnel. Check the oil level using the dipstick, which is usually attached to the oil fill cap.
- Insert the dipstick into the oil fill tube.
- Remove the dipstick and check the oil level.
- Add more oil if necessary, but do not overfill.
After adding the correct amount, replace the oil fill cap and tighten it securely. Your lawn mower is now ready for use.
Check Oil Level
Regularly checking the oil level in your lawn mower is essential. It ensures the engine runs smoothly and lasts longer. Here’s how to properly check the oil level in your lawn mower.
Use The Dipstick
First, locate the dipstick on your lawn mower. It’s usually near the engine. Pull the dipstick out and wipe it clean with a rag. This step removes old oil, giving you an accurate reading.
Next, insert the dipstick back into its tube. Push it all the way in. Now, pull the dipstick out again. Look at the oil level mark. The oil should be between the “Full” and “Add” marks.
Adjust Oil Level If Necessary
If the oil is below the “Add” mark, you need to add more oil. Use the recommended oil type for your mower. Slowly pour the oil into the oil fill tube. Check the level again with the dipstick.
On the other hand, if the oil level is too high, you need to remove some. Use an oil extractor pump for this. Overfilling can damage the engine. Make sure the oil level is just right.
Here’s a quick summary in a table:
Step | Action |
---|---|
1 | Locate and remove dipstick |
2 | Wipe dipstick clean |
3 | Reinsert and remove dipstick |
4 | Check oil level |
5 | Adjust oil level if needed |
Following these steps will help keep your lawn mower in top condition. Regular oil checks are key to a well-maintained machine.
Clean Up
After successfully changing the oil in your lawn mower, it’s crucial to clean up properly. This ensures a tidy workspace and safe disposal of old oil. Follow these steps to complete your oil change process smoothly.
Dispose Of Old Oil
Collect the old oil in a sealable container. Don’t pour it down the drain. Take it to a recycling center. Many auto parts stores also accept used oil. Check with local waste management services for guidelines. Proper disposal protects the environment.
Clean The Work Area
Wipe down any spills immediately. Use a rag or paper towels. Ensure no oil remains on the floor. Clean the tools you used. Put everything back in its place. A clean workspace prevents accidents. It also extends the life of your equipment. Regular maintenance keeps your lawn mower in top condition.
