The smell of freshly cut grass and the hum of a well-maintained lawnmower are the hallmarks of a perfect summer day. But like any machine, your lawnmower needs regular maintenance to run smoothly and last for years to come. One of the most important maintenance tasks is changing the oil. This article will guide you through the process of changing the oil in your lawnmower, ensuring your machine runs smoothly and efficiently for seasons to come. We’ll cover everything from choosing the right oil to proper disposal and safety precautions. Let’s get started!
A Quick Overview of Lawn Mower Oil Changes
Changing the oil in your lawnmower is essential for keeping the engine clean and lubricated, preventing wear and tear, and ensuring optimal performance. Over time, the oil breaks down, gets contaminated with debris, and loses its ability to effectively lubricate the engine. This can lead to engine damage and costly repairs. Regularly changing the oil helps to prevent this by flushing out the old oil and replacing it with fresh, clean oil.
Gather Your Supplies: Preparing for the Oil Change
Before you begin, gather the following tools and materials:
- New Lawn Mower Oil: Choose the correct oil for your mower’s engine. Refer to your owner’s manual for the recommended type and viscosity (weight).
- Oil Drain Pan: A container to catch the used oil.
- Oil Filter Wrench (if applicable): Some lawnmower engines have an oil filter that needs to be replaced during the oil change.
- Wrench or Socket: You’ll need this to loosen the oil drain plug.
- Shop Towels or Rags: These will be helpful for cleaning up spills.
- Gloves: Protect your hands from oil and dirt.
- Safety Glasses: Shield your eyes from any potential splashes.
Safety First: Prioritize Your Well-being
Before you start working on your lawnmower, prioritize your safety:
- Wear appropriate safety gear: Always wear gloves and safety glasses to protect your hands and eyes from oil and debris.
- Park the lawnmower on a level surface: This helps prevent the mower from rolling and causing injury.
- Disengage the spark plug: Disconnect the spark plug wire from the spark plug to prevent the engine from starting accidentally.
- Let the engine cool down: Allow the engine to cool completely before you begin the oil change. This will help prevent burns.
- Work in a well-ventilated area: Avoid changing the oil in a closed space, as oil fumes can be hazardous.
Steps to Change the Oil in Your Lawn Mower
Now that you’ve gathered your supplies and taken the necessary safety precautions, let’s get started on the oil change:
1. Locate the Oil Drain Plug
The oil drain plug is typically located on the bottom of the engine, usually marked with a small plug or a bolt.
2. Place the Drain Pan Underneath the Plug
Position the drain pan directly underneath the oil drain plug to catch the used oil as it drains.
3. Loosen and Remove the Oil Drain Plug
Use a wrench or socket to loosen and remove the oil drain plug. Be careful not to drop the plug into the drain pan.
4. Drain the Oil
Allow the oil to drain completely into the drain pan. It may take a few minutes for all of the oil to drain out.
5. Replace the Oil Drain Plug
Once the oil has drained, replace the oil drain plug and tighten it securely. Be sure to use a new crush washer if necessary.
6. Check for Leaks
After tightening the drain plug, check for any leaks. Wipe off any excess oil with a shop towel.
7. Locate the Oil Fill Cap
The oil fill cap is typically located on the top of the engine, usually marked with a symbol that looks like an oil can.
8. Add New Oil
Carefully pour the new oil into the fill cap until the oil level reaches the “Full” mark on the dipstick.
9. Replace the Oil Fill Cap
Securely replace the oil fill cap after adding the new oil.
10. Start the Engine and Check for Leaks
Start the engine for a few minutes and check for any oil leaks. If there are any leaks, re-tighten the oil drain plug and/or oil fill cap.
11. Dispose of the Used Oil Properly
Used motor oil is a hazardous material and should be disposed of properly. Many auto parts stores and recycling centers accept used motor oil for recycling.
Oil Change Tips and Tricks
Here are some additional tips to make your lawnmower oil change even smoother:
- Check your owner’s manual: The owner’s manual will specify the correct type and viscosity of oil for your specific lawnmower.
- Use a funnel: Using a funnel will help prevent spills and ensure that the new oil flows directly into the oil fill cap.
- Wipe up spills immediately: Clean up any spills promptly to prevent slipping hazards and contamination.
- Keep a record of your oil changes: Note the date of each oil change in your lawnmower’s maintenance log or on a calendar.
Benefits of Regular Oil Changes
Regular oil changes provide a range of benefits for your lawnmower:
- Improved performance: Fresh oil ensures optimal lubrication and reduces friction, resulting in smoother and more efficient engine operation.
- Increased engine life: Clean oil helps to prevent wear and tear on engine parts, extending the lifespan of your mower.
- Reduced emissions: Clean oil helps to reduce engine emissions, contributing to a cleaner environment.
- Lower maintenance costs: Regular oil changes can help prevent costly engine repairs.

Frequently Asked Questions
What kind of oil should I use in my lawn mower?
The type of oil you need for your lawn mower will depend on the engine. Most gas-powered lawn mowers use standard 10W-30 oil, which is a good all-around choice for most climates. However, you should always consult your owner’s manual for the specific type of oil recommended for your mower.
If you’re unsure, it’s always best to err on the side of caution and use a higher viscosity oil, such as 10W-40, especially if you live in a hot climate or if you plan on using your mower for extended periods.
How often should I change the oil in my lawn mower?
The frequency of oil changes for your lawn mower depends on several factors, including how often you use it, the type of oil you use, and the manufacturer’s recommendations. Generally, it’s a good idea to change the oil every 25 hours of use or at least once per season.
If you’re using your mower frequently, you may need to change the oil more often. If you’re unsure, it’s always best to check your owner’s manual for specific recommendations.
Where is the oil drain plug located?
The oil drain plug is typically located on the bottom of the engine, near the crankshaft. It is usually a hexagonal-shaped plug that can be unscrewed with a wrench.
However, the exact location can vary depending on the model of your lawn mower. If you can’t find the oil drain plug, refer to your owner’s manual or consult with a qualified mechanic.
Do I need to warm up the engine before changing the oil?
It’s generally a good idea to warm up the engine for a few minutes before changing the oil. This helps to thin the oil and make it easier to drain. However, it’s not essential, especially if you’re using your lawn mower frequently.
If you’re changing the oil while the engine is still hot, be careful not to burn yourself. Wear gloves and use a wrench to loosen the drain plug.
How do I know if I need to change the oil?
There are a few signs that indicate you need to change the oil in your lawn mower. The oil may be discolored, dark, or even milky, indicating the presence of water or other contaminants. You may also notice a decrease in engine performance, such as difficulty starting or a loss of power.
If you’re unsure, it’s always a good idea to check your oil regularly and change it according to the manufacturer’s recommendations.
What should I do with the old oil?
Dispose of old oil responsibly. It’s illegal to dump it down the drain or into the garbage. Check with your local municipality or a recycling center to find out how to dispose of it properly.
Many auto parts stores and garages offer oil recycling services, and you can usually find designated oil recycling bins at gas stations.
Can I reuse the oil?
It’s not recommended to reuse oil in your lawn mower. Once the oil has been used, it contains contaminants and debris that can damage the engine.
Using fresh oil ensures that your lawn mower runs smoothly and efficiently. Always dispose of old oil properly to avoid environmental harm.
