Your lawn mower, a trusty companion in your quest for a perfectly manicured lawn, requires regular maintenance. One crucial aspect of this maintenance is changing the oil. This seemingly simple task is essential for keeping your engine running smoothly and preventing costly repairs. But how do you empty the old oil out safely and effectively? This comprehensive guide will walk you through the process step-by-step, ensuring you can tackle this task with confidence.
In short, draining the oil from your lawn mower involves a few key steps:
- Prepare your workspace: You’ll need a suitable location, safety gear, and the right tools.
- Warm up the engine: This helps the oil flow more easily.
- Locate the drain plug: It’s usually on the bottom of the engine.
- Catch the old oil: Use a container specifically designed for oil disposal.
- Clean and reinstall the drain plug: Ensure a tight seal to prevent leaks.
- Dispose of the old oil properly: Recycling or disposing of it responsibly is vital.
Setting the Stage for a Successful Oil Change
Before you dive into the actual draining process, it’s important to prepare your workspace and gather the necessary tools. This will ensure a smooth and safe operation.
1. Choose a Suitable Location
A flat, level surface is ideal for your lawn mower oil change. Look for a spot that’s well-ventilated and away from any potential hazards.
2. Gather Your Gear
- Oil drain pan: A container designed specifically for used oil is essential for capturing the drained oil. These pans are typically made of metal or plastic and have a spout for easy pouring.
- Wrench or socket: You’ll need a wrench or socket that fits the size of your drain plug. Check your mower’s manual or identify the size directly from the plug itself.
- Gloves: Protective gloves are important for handling the used oil, which can be messy and potentially harmful to your skin.
- Cleaning rags: Have a few cleaning rags handy for wiping up spills and cleaning the drain plug area.
- New engine oil: Always have fresh engine oil ready to refill your mower once the old oil is drained. Refer to your mower’s manual for the recommended type and quantity.
- Funnel: A funnel can help you add the fresh oil smoothly into the mower’s engine.
Let’s Get to the Draining
Now that you’ve set the stage, it’s time to tackle the oil draining itself.
1. Warm Up the Engine (Optional)
While not strictly necessary, warming up the engine for a few minutes can make the oil thinner and easier to drain. This is especially helpful if your lawn mower hasn’t been used recently. Start the engine and let it run for a couple of minutes, but be cautious to avoid overheating.
2. Locate the Drain Plug
The drain plug is typically located at the bottom of the engine block, usually near the oil pan. It’s often a hexagonal-shaped plug with a threaded hole. If you can’t locate the drain plug, consult your lawn mower’s manual.
3. Secure Your Oil Drain Pan
Position the oil drain pan beneath the drain plug. Ensure the pan is positioned correctly to catch all the draining oil.
4. Remove the Drain Plug
Using your wrench or socket, carefully loosen the drain plug. Be prepared for oil to start draining out immediately. Once the plug is loose, you can turn it by hand to remove it fully.
5. Allow the Oil to Drain Completely
Let the oil drain completely into the pan. You can gently tip the mower to help the last drops of oil flow out.
6. Clean and Reinstall the Drain Plug
Once the oil has drained, clean the drain plug and the surrounding area with a rag. This removes any oil residue and prevents potential clogging or leaks.
Important Note: When re-installing the drain plug, ensure that it is tightly secured, but avoid over-tightening. Overtightening can damage the threads.
The Final Touches: Cleaning Up and Filling Up
With the old oil drained, you’re almost done. It’s time to dispose of the old oil properly and fill the engine with fresh oil.
1. Dispose of the Used Oil
Used engine oil is hazardous and should not be disposed of in the trash.
- Recycle: Check with your local recycling center or garage to see if they accept used motor oil. Many recycling centers offer free oil recycling services.
- Dispose Properly: If recycling isn’t an option, dispose of the oil in accordance with your local regulations. Often, you can find designated oil disposal bins at car part stores or automotive repair shops.
2. Refill with Fresh Oil
Refer to your lawn mower’s manual for the type and amount of oil required.
- Insert Funnel: Use a funnel to carefully pour the fresh oil into the engine’s oil fill hole.
- Check Oil Level: Once the oil is added, check the dipstick to ensure the oil level is at the correct mark. You may need to add more or remove some depending on the level.
3. Start the Engine
With the fresh oil added, start the engine and let it run for a minute or two. This allows the new oil to circulate throughout the engine.
4. Check for Leaks
After the engine has warmed up, shut it off and check for any leaks around the drain plug and oil fill hole. If you notice any leaks, immediately tighten the plug or oil fill cap.
Keeping Your Lawn Mower in Top Shape
Changing the oil in your lawn mower is a simple but crucial maintenance task that ensures the longevity and smooth operation of your machine. By following these steps, you can confidently drain the old oil and refill with fresh oil, ensuring your lawn mower runs efficiently for seasons to come.
Here are some additional tips for optimal lawn mower maintenance:
- Check Your Manual: Always refer to your lawn mower’s manual for specific oil recommendations and maintenance schedules.

By taking the time to maintain your lawn mower properly, you’ll enjoy a smooth running engine and a beautiful, healthy lawn for years to come.
Frequently Asked Questions
How often should I change the oil in my lawn mower?
It’s recommended to change the oil in your lawn mower every 25 hours of use or at the beginning of each season, whichever comes first. This helps ensure the engine runs smoothly and prevents wear and tear. If you don’t use your mower frequently, it’s still a good idea to change the oil at least once a year.
What kind of oil should I use for my lawn mower?
The type of oil you use will depend on your lawn mower’s engine. Most modern lawn mowers use 4-stroke engines and require SAE 30 oil or 10W-30 oil. However, always refer to your owner’s manual for the specific oil recommendation for your model. Using the wrong type of oil can damage your engine.
What tools do I need to change the oil in my lawn mower?
You’ll need a few basic tools for changing the oil. These include a drain pan, a wrench or socket that fits the oil drain plug, a funnel, and of course, the new oil. You may also want to have a pair of gloves and some rags handy for cleanup.
How do I know when the oil is full?
When adding new oil, you want to fill the crankcase to the “full” mark on the dipstick. This mark is usually indicated by a line or a series of lines on the dipstick. Do not overfill the crankcase, as this can cause engine damage.
What should I do with the old oil?
Used motor oil is hazardous waste and should be disposed of properly. Do not pour it down the drain or into the ground. Many auto parts stores and recycling centers have oil disposal containers. You can also check with your local waste management department for information on proper disposal methods.
What if I accidentally overfill the crankcase?
If you overfill the crankcase, it’s important to remove the excess oil immediately. To do this, you can use a suction tool or a syringe to carefully draw out the excess oil. Be sure to check the oil level again after removing the excess oil to ensure that the crankcase is filled to the correct level.
What should I do if I see smoke coming from the engine while I’m changing the oil?
If you see smoke coming from the engine while changing the oil, immediately stop and turn off the engine. This could indicate a serious problem, such as a leak in the engine or a damaged gasket. Consult your owner’s manual or a qualified mechanic for assistance.
