If you’re like most homeowners, you probably don’t think about changing the oil in your push mower very often. However, it’s an important part of keeping your mower running smoothly and efficiently. Over time, oil can become contaminated with dirt, grass clippings, and other debris. This can cause the oil to lose its lubricating properties and lead to premature wear and tear on your mower’s engine. Changing the oil in your push mower is a relatively simple task that can be completed in just a few minutes. By following the steps below, you can help keep your mower running smoothly for years to come.
First, you’ll need to gather a few supplies. You’ll need a new bottle of oil, a funnel, and a wrench. You may also want to wear gloves to protect your hands from the oil. Once you have your supplies, you can begin the process of changing the oil.
Start by locating the oil dipstick. On most push mowers, the oil dipstick is located on the side of the engine. Pull out the dipstick and wipe it clean with a rag. Then, reinsert the dipstick into the engine and pull it out again. The oil level should be between the two marks on the dipstick. If the oil level is low, you’ll need to add more oil.
Gathering Essential Tools and Materials
Before embarking on the task of changing the oil in your push mower, it’s crucial to gather the necessary tools and materials. This will ensure a smooth and efficient process. Here’s a detailed checklist of what you’ll need:
Tools:
– **Wrench or Socket**: To loosen and remove the drain plug.
– **Funnel**: To guide the new oil into the engine.
– **Oil filter wrench (if applicable)**: Some mowers have oil filters that need to be replaced.
– **Rags or paper towels**: To clean up any spills or wipe down the mower.
Materials:
– **New oil**: Consult your mower’s manual for the recommended oil type and quantity.
– **Oil filter (if applicable)**: Only needed if your mower has a replaceable oil filter.
– **Oil drain pan**: To collect the old oil.
– **Safety glasses**: To protect your eyes from splashing oil.
– **Gloves**: To protect your hands from hot oil.
Tips for Selecting Oil:
| Oil Type | Recommended Use |
|---|---|
| SAE 30 | For general-purpose use in most climates |
| SAE 10W-30 | For use in colder climates or for mowers that are used frequently |
| SAE 5W-30 | For use in very cold climates or for high-performance mowers |
Safety Precautions before Starting
Gather Necessary Tools and Materials
Before commencing the oil change, ensure you have all the essential tools and materials. This typically includes a new oil filter, fresh oil, a socket wrench, an oil pan, gloves, and rags. Consult your mower’s user manual for specific requirements.
Prepare the Mower
1. Ensure that the mower is parked on a stable, level surface.
2. Disconnect the spark plug wire to prevent accidental starting.
3. Allow the engine to cool completely before proceeding. Hot oil can cause burns.
Locate the Oil Drain Plug
4. Place the oil pan beneath the mower.
5. Locate the oil drain plug, which is usually at the bottom of the engine. It may have a bolt or cap.
6. Using the socket wrench, carefully loosen the drain plug but do not remove it completely yet.
Drain the Old Oil
7. Allow the old oil to drain into the oil pan. This may take several minutes.
8. Be patient and do not rush the process. Avoid spilling oil on the ground or yourself.
9. Once all the oil has drained, remove the drain plug completely and clean any debris from it.
Checking the Oil Level
Locate the oil dipstick, which is usually attached to the oil filler cap. Pull it out and wipe it clean with a rag. Reinsert the dipstick fully, then pull it out again to check the oil level. The oil level should be between the two marks on the dipstick, indicating “low” and “full.”
Draining the Old Oil
Place an oil drain pan under the engine. Loosen the oil drain plug with a wrench, allowing the oil to drain into the pan. Be careful not to overtighten the drain plug when replacing it.
Replacing the Oil Filter (Optional)
Locate the oil filter and remove it using an oil filter wrench. Apply a thin layer of new oil to the gasket of the new oil filter and screw it into place by hand. Do not overtighten the filter.
Refilling the Engine with New Oil
Refer to your owner’s manual to determine the recommended oil type and capacity for your mower. Add new oil to the engine through the oil filler hole using a funnel. Pour slowly and check the oil level frequently using the dipstick.
Once the oil level reaches the “full” mark on the dipstick, replace the oil filler cap and start the mower. Let it run for a few minutes to circulate the new oil. Stop the mower and recheck the oil level to ensure it has not dropped.
**Tips for Refilling the Engine with New Oil**
| Tip | Description |
|---|---|
| Use the recommended oil type | Check your owner’s manual for the specific oil type required for your mower. |
| Add oil gradually | Pour the oil slowly and check the level frequently to avoid overfilling. |
| Check the oil level after running | Run the mower for a few minutes and then recheck the oil level to ensure it has not dropped. |
| Dispose of used oil properly | Dispose of used oil at a recycling center or hazardous waste facility. |
Gather Your Tools and Materials
Before starting the oil change, ensure you have all the necessary tools and materials. These include:
- New oil
- Oil filter (if applicable)

Troubleshooting Common Issues
1. The engine won’t start after an oil change.
Ensure the oil level is correct. Overfilling or underfilling the oil can cause the engine to run poorly or not at all. Also, make sure that the oil you used is the correct type for your mower.
2. The mower is smoking.
If you notice blue smoke coming from the mower, it could indicate that oil is burning in the engine. This can be caused by worn piston rings or a damaged cylinder.
3. The mower is leaking oil.
Check the oil pan, drain plug, and oil filter for leaks. Tighten any loose bolts or fittings, and replace the oil filter if necessary.
4. The mower is making a knocking noise.
A knocking noise can indicate that the engine is not getting enough oil. Check the oil level and add oil if necessary.
5. The mower is losing power.
A dirty or clogged air filter can restrict airflow to the engine, causing it to lose power. Replace the air filter regularly.
6. The mower is running rough.
If the mower is running rough, it could be due to a dirty carburetor. Clean the carburetor according to the manufacturer’s instructions.
7. The mower is overheating.
Overheating can be caused by a lack of oil or a clogged cooling system. Check the oil level and clean the cooling system.
8. The mower has a hard time starting when it’s cold.
If your mower has a hard time starting when it’s cold, it could be due to a weak battery or a faulty starter. Check the battery and starter, and replace them if necessary. You can also try using a starting fluid to help the engine start.

Clean the deck regularly, especially after mowing wet grass, to prevent rust.
To clean the mower deck, you can use the following materials:
| Material | Use |
|---|---|
| Putty knife | To scrape off stubborn grass clippings |
| Brush | To remove loose debris |
| Compressed air | To blow out hard-to-reach areas |
Safety Precautions after Oil Change
Special Disposal
Used motor oil and filters contain harmful chemicals that can contaminate the environment. Dispose of them responsibly at designated recycling centers. Check with your local government or auto parts store for proper disposal methods.
Post-Change Inspection
After replacing the oil and filter, start the mower and let it run for a few minutes. Check for any leaks from the oil drain plug or filter. If any leaks are observed, tighten the components or replace the faulty parts.
Regular Oil Changes
Continue to change the oil regularly according to the manufacturer’s recommendations. Consistent oil changes help extend the life of the mower and prevent costly repairs.
Clean the Filter Regularly
In addition to changing the oil, clean the air filter regularly to prevent dirt and debris from entering the engine. A clean air filter ensures efficient combustion and reduces engine wear.
Use High-Quality Oil
Always use high-quality oil recommended by the manufacturer. Using inferior oil can harm the engine and compromise its performance.
Check Oil Level Regularly
Between oil changes, check the oil level regularly using the dipstick provided. If the oil level is low, add the recommended oil type to the engine.
Store Mower Properly
When storing the mower for an extended period, drain the fuel and remove the spark plug. Store the mower in a dry, well-ventilated area to prevent rust and other damage.
Additional Safety Considerations
- Wear gloves and safety glasses when handling used oil and filters.
- Never smoke or have open flames near the mower while servicing.
- Keep children and pets away from the mower during maintenance.
