This comprehensive guide will walk you through every step, from gathering the necessary supplies to safely disposing of the old oil. Whether you’re a seasoned lawn care enthusiast or a novice gardener, this guide has you covered.
Changing your lawnmower’s oil is a relatively simple task that can be done by most homeowners. It typically takes about 30 minutes and requires only a few basic tools. By following the steps outlined in this guide, you can ensure your mower is running efficiently and maximizing its performance.
Preparing for the Oil Change: Safety First
Before you dive into changing the oil, it’s essential to prioritize safety.
1. Safety Gear
- Wear safety glasses: This will protect your eyes from any oil splashes or debris.
- Gloves: Protect your hands from the oil and grime.
- Closed-toe shoes: You’ll be working around hot engine parts, so closed-toe shoes are a must.
2. Gathering Your Supplies
To complete the oil change, you’ll need the following:
- Fresh lawnmower oil: Consult your owner’s manual for the correct type and viscosity.
- Oil drain pan: This will catch the old oil.
- Oil filter wrench: If your mower has a replaceable oil filter, you’ll need a wrench specifically designed for it.
- Wrench or socket: This will be needed to loosen the drain plug.
- Funnel: A funnel makes pouring fresh oil much easier.
- Rags: Clean rags will be useful for wiping up any spills.
- Protective gear: Safety glasses, gloves, and closed-toe shoes.
3. Pre-Change Preparations
- Park the mower on a level surface: This will help prevent spills.
- Let the engine cool down: Never work on a hot engine. Give it ample time to cool before proceeding.
- Locate the drain plug and oil filter (if applicable): Your owner’s manual will provide the exact locations on your specific mower model.
Changing the Oil: A Step-by-Step Guide
Now that you’ve gathered your supplies and taken the necessary precautions, you’re ready to change the oil.
1. Draining the Old Oil
- Position the drain pan: Place the drain pan directly under the drain plug to catch the used oil.
- Loosen the drain plug: Use a wrench or socket to carefully loosen the drain plug. It’s a good practice to wrap the plug with a rag to ensure a good grip.
- Allow the oil to drain completely: Give the oil time to fully drain into the pan. This may take several minutes.
2. Replacing the Oil Filter (If Applicable)
- Locate the oil filter: It’s usually located near the engine and may have a housing.
- Loosen the oil filter: Use an oil filter wrench to loosen the filter. It may be necessary to turn it counterclockwise.
- Remove the old filter: Once loosened, the filter should easily come off.
- Clean the filter housing: Remove any dirt or debris from the filter housing to prevent contamination.
- Install the new filter: Apply a thin layer of fresh oil to the new filter’s gasket. This will help ensure a tight seal. Screw the filter on hand-tight. Do not overtighten.
3. Adding Fresh Oil
- Locate the oil fill cap: This is usually on the top of the engine.
- Pour the fresh oil: Use a funnel to slowly pour the recommended amount of fresh oil into the fill cap. Be sure to refer to your owner’s manual for the specific amount required.
- Check the oil level: After adding the oil, check the dipstick to ensure the oil level is within the recommended range.
- Tighten the fill cap: Securely tighten the fill cap to prevent leaks.
Final Steps: Cleaning Up and Disposing of Used Oil
You’re nearly finished!
1. Cleaning Up
- Wipe up any spills: Use clean rags to wipe up any oil spills on the mower or surrounding area.
- Clean your tools: Wash your tools and dispose of them appropriately.
2. Disposing of Used Oil
- Proper disposal: Never pour used oil down the drain or into the ground. It’s a hazardous waste and can contaminate water sources.
- Recycling options: Many auto parts stores and recycling centers accept used oil for proper disposal.
- Check your local regulations: Contact your local waste management authority for information on oil disposal in your area.
Maintaining Your Lawn Mower for Optimal Performance
Changing the oil regularly is crucial for keeping your lawnmower running smoothly and maximizing its lifespan.
1. Frequency of Oil Changes
- Check your owner’s manual: The recommended oil change interval will vary depending on your mower model and how frequently you use it. Generally, oil changes are recommended every 25 hours of operation.
- Pay attention to the oil condition: If the oil is dark or has a burnt smell, it’s time for a change.
2. Other Maintenance Tasks
In addition to changing the oil, other regular maintenance tasks can extend your mower’s life:
- Spark plug inspection and replacement: Check the spark plug for wear and tear and replace it as needed.
- Air filter cleaning: A clean air filter helps your engine breathe properly.
- Blade sharpening: Sharp blades ensure a clean cut and reduce strain on your engine.

FAQ
How often should I change my lawnmower oil?
It is generally recommended to change your lawnmower oil every 25 hours of use or at the beginning of each mowing season, whichever comes first. This helps to keep your lawnmower engine running smoothly and prevents wear and tear. However, always consult your owner’s manual for specific recommendations as the frequency might vary based on your lawnmower model and usage.
What type of oil should I use for my lawnmower?
The best oil for your lawnmower is typically a 4-stroke SAE 30 oil. Some lawnmower engines may require a specific type of oil, so it’s crucial to refer to your owner’s manual for the recommended type of oil. Using the wrong type of oil can damage your lawnmower engine.
Do I need to warm up the engine before changing the oil?
It is advisable to warm up your lawnmower engine for a few minutes before changing the oil. This allows the oil to thin out, making it easier to drain. However, don’t let the engine get too hot. A warm engine is enough, not hot.
How much oil do I need to add?
The amount of oil needed for your lawnmower is specified in the owner’s manual. Generally, you should fill the oil reservoir until it reaches the “full” mark on the dipstick. Avoid overfilling, as this can cause engine damage.
Can I use the same oil for my car in my lawnmower?
It is generally not recommended to use car oil in your lawnmower. Car oil is formulated for higher-temperature and higher-stress conditions than lawnmower engines. Using car oil in your lawnmower can lead to engine damage.
What should I do with the used oil?
Do not pour used oil down the drain or into the environment. Used oil should be disposed of properly. Look for designated oil recycling centers in your area or contact your local waste management facility for guidance.
What should I do if I accidentally overfilled the oil?
If you have overfilled the oil, you can use a suction pump or a syringe to remove the excess oil. Be careful not to damage the engine or surrounding components while extracting the oil. It’s best to consult your owner’s manual or a professional mechanic if you are unsure about the process.
