The sweet scent of freshly cut grass, the satisfying whir of the engine, and the feeling of accomplishment as your lawn transforms – these are the joys of owning a lawn mower. But just like any machine, your trusty mower needs regular maintenance to keep it running smoothly. One of the most important tasks is changing the oil.
This guide will walk you through the process of changing your lawn mower oil, step by step. We’ll cover everything from choosing the right oil to properly disposing of the old oil, ensuring you have all the necessary tools and knowledge to keep your mower in tip-top shape.
The Importance of Changing Your Lawn Mower Oil
Your lawn mower’s engine needs oil to lubricate moving parts, reduce friction, and prevent wear and tear. Over time, the oil breaks down, loses its lubricating properties, and can even become contaminated with dirt and debris. Failing to change the oil regularly can lead to:
- Engine damage: Without proper lubrication, engine parts can overheat, seize, and eventually fail.
- Reduced performance: A dirty engine will run less efficiently, consuming more fuel and producing less power.
- Increased emissions: A poorly maintained engine can release harmful pollutants into the environment.
By changing the oil regularly, you can extend the life of your lawn mower, ensure its optimal performance, and reduce your environmental impact.
Tools and Materials
Before you get started, gather the following tools and materials:
- New lawn mower oil: Choose the correct type of oil for your mower, which is typically specified in your owner’s manual.
- Oil drain pan: This will catch the old oil as you drain it.
- Wrench: Use a wrench that fits the oil drain plug on your mower.
- Oil filter wrench (if applicable): Some lawn mowers have an oil filter that needs to be replaced.
- Rag or paper towels: For wiping up spills and cleaning parts.
- Gloves: Protect your hands from oil and dirt.
- Safety glasses: Protect your eyes from debris and spills.
- Owner’s manual: Consult your owner’s manual for specific instructions for your mower model.
Step-by-Step Guide: Changing Your Lawn Mower Oil
Now that you have everything you need, follow these steps to change the oil in your lawn mower:
1. Prepare Your Work Area
- Find a flat, level surface: This will make it easier to work on the mower.
- Park the mower on a non-flammable surface: This is important for safety reasons, as oil spills can be a fire hazard.
- Turn off the engine and allow it to cool down completely: This will prevent burns and reduce the risk of oil spilling.
2. Locate the Oil Drain Plug
- Consult your owner’s manual: The location of the oil drain plug can vary depending on the mower model.
- The drain plug is typically located on the bottom of the engine: It may have a small hex head or a square shape.
3. Drain the Old Oil
- Place the oil drain pan underneath the drain plug: Ensure it is positioned to catch all the oil as it drains.
- Loosen the drain plug with the wrench: Turn it counterclockwise until the oil starts to flow out.
- Let the oil drain completely: This may take a few minutes.
- Tighten the drain plug: Once all the oil has drained, tighten the drain plug back to its original tightness.
4. Replace the Oil Filter (if applicable)
- Locate the oil filter: It is typically located near the oil drain plug.
- Loosen the filter with an oil filter wrench: Turn it counterclockwise until it comes loose.
- Remove the old filter: Discard the old filter properly.
- Install the new filter: Screw the new filter on by hand until it is snug. Then, use the filter wrench to tighten it an additional 1/2 to 3/4 turn.
5. Add New Oil
- Check your owner’s manual: It will specify the correct oil type and capacity for your mower.
- Pour the new oil into the oil fill opening: Located on the top of the engine.
- Add oil slowly: Watch the dipstick as you add oil.
- Check the oil level: Wipe the dipstick clean, insert it fully, then remove it and check the oil level. It should be between the “full” and “add” marks.
6. Clean Up and Dispose of Oil Properly
- Wipe up any spills: Use a rag or paper towels to clean up any oil spills.
- Dispose of the old oil properly: Do not pour it down the drain or into the ground. Check with your local waste management facility for proper disposal instructions. Many auto parts stores have oil recycling bins.
7. Start the Engine and Check for Leaks
- Start the engine and let it run for a few minutes: This will allow the oil to circulate.
- Check for leaks: Inspect the oil drain plug, oil filter, and oil fill area for any leaks.
- Shut down the engine and let it cool down: Once you have confirmed there are no leaks, shut off the engine and let it cool down completely.
Tips and Considerations
- Check the oil level regularly: Even if you just changed the oil, it’s a good idea to check the level every few hours of operation, especially in the early stages after an oil change.
- Keep track of oil changes: Write down the date of the oil change so you can remember when it’s time for the next one.
- Consider using a synthetic blend oil: These oils last longer and offer better performance, but they can be more expensive.
- Follow the manufacturer’s recommendations: Always refer to your lawn mower’s owner’s manual for specific instructions and recommendations.
Conclusion
Changing the oil in your lawn mower is a simple task that takes only a few minutes, but it’s an important one for keeping your mower running smoothly and extending its lifespan. By following the steps outlined in this guide and using the right tools and materials, you can ensure that your lawn mower is ready to tackle any lawn care challenge with ease.
FAQ
Why is it important to change the oil in my lawn mower?
Changing the oil in your lawn mower regularly is essential for its longevity and performance. Old oil becomes contaminated with dirt, metal shavings, and other debris, which can clog internal components and lead to wear and tear.

How often should I change the oil in my lawn mower?
The frequency of oil changes depends on the type of mower and its usage. For most gasoline-powered lawn mowers, it’s recommended to change the oil every 25 hours of operation or at least once per season. If you use your mower extensively, you may need to change the oil more frequently.
Consult your owner’s manual for specific recommendations regarding your model. It’s always better to err on the side of caution and change the oil a bit sooner than later.
What type of oil should I use for my lawn mower?
The type of oil required for your lawn mower will vary based on the engine size and specifications. Typically, lawn mowers use a 4-stroke engine oil, but it’s crucial to check your owner’s manual for the recommended oil viscosity and type.
Using the correct oil ensures proper lubrication and protects your engine from damage. Always use high-quality oil formulated for lawn mower engines, as they are subjected to high temperatures and demanding conditions.
