The first warm days of spring are finally here, beckoning you to tackle your lawn care chores. But before you fire up your trusty push lawn mower, it’s crucial to give it some TLC. Just like your car, your lawn mower needs regular oil changes to run smoothly and efficiently. A neglected oil change can lead to engine wear and tear, ultimately shortening your mower’s lifespan. Fortunately, changing the oil on a push lawn mower is a simple and straightforward process that even a beginner can handle. This comprehensive guide will walk you through every step, from gathering the necessary tools to disposing of the old oil properly.
A Brief Overview:
Changing the oil in your push lawn mower is a routine maintenance task that involves draining the old oil, replacing it with fresh oil, and ensuring the proper oil level. The entire process typically takes less than 30 minutes and requires minimal tools. Let’s delve into the specifics!
Gathering Your Supplies:
Before you begin, you’ll need a few essential supplies. This will ensure a smooth and efficient oil change:
1. New Lawn Mower Oil:
- Choose the correct type of oil specifically designed for lawn mowers. Consult your owner’s manual for the recommended oil viscosity (e.g., SAE 30 or SAE 10W-30).
- Purchase the appropriate amount of oil. Most push mowers require around 18-20 ounces of oil.
- It’s generally recommended to use high-quality oil, even if the manual doesn’t specify it.
2. Oil Drain Pan:
- This will catch the old oil as you drain it. A small, disposable oil drain pan is ideal for this purpose.
- Make sure the pan is large enough to hold the entire amount of oil in your mower.
3. Wrench or Socket:
- You’ll need a wrench or socket that fits the oil drain plug on your mower.
- The size of the wrench will vary depending on the mower model.
- If you’re unsure, check your owner’s manual or use a set of wrenches to find the right size.
4. Rags or Paper Towels:
- Use these to clean up any oil spills during the process.
- Keep a few extras handy for unexpected messes.
5. Protective Gear:
- Wear gloves to protect your hands from oil.
- Consider safety glasses to shield your eyes from any oil splashes.
Pre-Preparation:
Before diving into the actual oil change process, it’s crucial to take some preparatory steps to ensure a safe and smooth procedure:
1. Allow the Engine to Cool Down:
- After your last mow, let the engine cool down completely. Attempting to drain hot oil can lead to burns.
- Wait at least 30 minutes before proceeding.
2. Find a Safe and Suitable Workspace:
- Choose a flat, level surface to work on. A driveway or garage floor are good options.
- Ensure the area is well-ventilated to prevent any buildup of fumes.
3. Locate the Oil Drain Plug:
- Refer to your owner’s manual for the exact location of the oil drain plug on your specific mower model.
- Typically, it’s found on the bottom of the engine housing.
4. Place the Oil Drain Pan:
- Position the oil drain pan directly underneath the oil drain plug. This will catch the oil as it drains.
5. Prepare the New Oil:
- Ensure you have the correct type and amount of oil readily available.
- If using a bottle with a spout, remove the cap to make pouring easier.
The Oil Change Process:
Now that you’ve gathered your supplies and prepared your workspace, you’re ready to tackle the actual oil change:
1. Loosen the Oil Drain Plug:
- Using your wrench or socket, loosen the oil drain plug by turning it counterclockwise.
- Be careful not to overtighten the drain plug when you reinstall it.
- The oil will start to drain as soon as the plug is loosened.
2. Drain the Oil:
- Allow the oil to drain completely. It may take a few minutes for all the oil to flow out.
- Observe the color and consistency of the old oil. If it’s dark, thick, or contains sludge, it’s a clear indication that the oil needs changing.
3. Remove the Oil Drain Plug:
- Once the oil has drained completely, remove the oil drain plug entirely.
- Inspect the plug for any damage or wear. Replace it if necessary.
4. Clean the Oil Drain Plug and Area:
- Using a rag or paper towel, wipe the oil drain plug clean of any debris or oil residue.
- Also, clean the surrounding area where the plug was located to prevent any oil from getting trapped in the threads.
5. Reinstall the Oil Drain Plug:
- Carefully screw the oil drain plug back into its position.
- Hand-tighten it securely, but avoid overtightening.
6. Add New Oil:
- Locate the oil filler cap on your mower. It’s usually located on the top of the engine.
- Carefully pour the new oil into the filler opening until the level reaches the fill line indicated on the dipstick.
- Don’t overfill the crankcase.
7. Check the Oil Level:
- Once you’ve added the new oil, wipe the dipstick clean and reinsert it.
- Remove the dipstick and check the oil level. It should be between the “Full” and “Add” marks on the dipstick.
- If the oil level is too low, add more oil as needed.
- If the oil level is too high, carefully remove some oil with a syringe or oil extractor.
8. Clean Up:
- Once you’re satisfied with the oil level, dispose of the used oil properly.
- Never pour used oil down the drain or into the garbage.
- Check with your local waste disposal facility for information on how to properly dispose of used oil.
- Wipe up any spills and clean your tools.
9. Start the Engine:
- Once you’ve finished changing the oil, start the engine and let it run for a few minutes.
- This will allow the new oil to circulate and check for any leaks.
10. Check for Leaks:
- After the engine has been running for a few minutes, shut it off and inspect the area around the drain plug and filler cap for any leaks.
- If you see any leaks, tighten the plug or cap as needed.
Maintenance Tips and Recommendations:
- Consult your owner’s manual for specific recommendations on oil type, viscosity, and change intervals.
- Consider using a high-quality oil designed specifically for lawn mowers.
- If you use your lawn mower frequently, consider changing the oil more often.
- Replace the oil filter annually or at least every other oil change.
- Regular oil changes will help keep your mower running smoothly and efficiently, extending its lifespan.
Conclusion:
Changing the oil in your push lawn mower is a simple yet crucial maintenance task that keeps your mower running smoothly and efficiently. This step-by-step guide provides a comprehensive overview of the process, from gathering the necessary tools to disposing of the old oil properly.

Frequently Asked Questions
What type of oil should I use for my push lawn mower?
The type of oil you need for your push lawn mower will depend on the engine’s specifications. Most small lawn mower engines use SAE 30 oil, but it’s always best to check the owner’s manual for the recommended oil type. It’s important to use the correct type of oil to ensure proper lubrication and prevent engine damage.
How often should I change the oil in my push lawn mower?
The frequency of oil changes in your push lawn mower will vary based on usage and the manufacturer’s recommendations. However, a general guideline is to change the oil every 25 hours of operation or at the beginning of each mowing season. You can also check the oil’s condition; if it appears dark or gritty, it’s time for a change.
What tools do I need to change the oil in my push lawn mower?
You’ll need a few basic tools to change the oil in your push lawn mower. These include a wrench or socket that fits the oil drain plug, an oil pan or container to catch the used oil, a funnel to pour in the new oil, and a few rags for cleanup. Additionally, a pair of gloves is recommended to protect your hands from the oil.
Can I change the oil without the engine running?
Yes, you can safely change the oil in your push lawn mower with the engine off. In fact, it’s recommended to change the oil with the engine cold, as the oil will be thicker and easier to drain.
How do I know when my lawn mower is out of oil?
Most lawn mowers have a dipstick that allows you to check the oil level. To check the oil level, remove the dipstick, wipe it clean, and insert it back into the dipstick tube. Remove the dipstick again and check the oil level. The oil level should be between the “full” and “low” marks on the dipstick. If the oil level is low, add oil until it reaches the “full” mark.
What should I do with the old oil?
Never dispose of used oil down the drain or into the trash. It’s harmful to the environment and can contaminate water sources. Instead, take the used oil to a local recycling center or auto parts store that accepts used oil for proper disposal.
What should I do if I spill oil while changing it?
If you spill oil while changing it, use an absorbent material like kitty litter or sawdust to soak up the spill. Dispose of the absorbent material properly, following your local guidelines. It’s important to clean up any spills immediately to prevent them from contaminating the environment.
