A Quick Overview
Changing the oil in your riding lawn mower is essential for maintaining its longevity and performance. Regular oil changes prevent engine wear, reduce friction, and help keep your mower running cool. This process typically involves draining the old oil, replacing the oil filter, and adding fresh oil.
Getting Ready: The Essentials for a Successful Oil Change
Before you start, gather the following materials:
- New engine oil: Refer to your owner’s manual for the correct type and viscosity.
- New oil filter: Check your owner’s manual for the correct filter type.
- Oil drain pan: This will catch the old oil as you drain it.
- Wrench or socket: This will be needed to loosen the oil drain plug.
- Oil filter wrench: This will be needed to remove the old oil filter.
- Gloves: Protect your hands from oil and dirt.
- Rag or paper towels: For cleaning up spills and wiping down surfaces.

- Safety glasses: Protect your eyes from splashes.
Step 1: Choosing the Right Oil
The type of oil you choose for your riding lawnmower is crucial for optimal performance and engine health. Consulting your owner’s manual is the most reliable source of information. Here’s what you need to consider:
Oil Type:
- Conventional Oil: This is the most affordable option and provides decent lubrication.
- Synthetic Oil: Offers superior performance in extreme temperatures and lasts longer than conventional oil.
- Semi-Synthetic Oil: A blend of synthetic and conventional oil, providing a balance of performance and affordability.
Oil Viscosity:
The viscosity of oil refers to its thickness, measured in SAE (Society of Automotive Engineers) grades. The correct viscosity for your riding lawnmower will be listed in your owner’s manual.
Important Note:
Never mix different types of oil (conventional, synthetic, semi-synthetic). Doing so can compromise the performance and lifespan of your engine.
Step 2: Warming Up the Engine
Before you start draining the oil, warm up the engine for a few minutes. This helps thin out the oil, allowing it to flow more easily out of the engine.
Step 3: Prepare the Drain Pan and Secure Your Mower
Position the oil drain pan beneath the oil drain plug. This will catch the used oil as you drain it. Ideally, position the mower on a level surface to ensure proper oil drainage.
Step 4: Loosen the Oil Drain Plug
Locate the oil drain plug, usually situated at the bottom of the engine block. Use the wrench or socket to loosen the drain plug, but don’t fully remove it yet. Once you have the plug loosened, let the oil drain completely into the pan.
Tip:
To prevent oil from dripping onto the ground, you can insert a small piece of cardboard into the oil drain pan. The cardboard will absorb any oil that drips outside the pan.
Step 5: Remove the Oil Filter
Locate the oil filter, which is typically found near the top of the engine. Use the oil filter wrench to loosen the filter. Once loosened, carefully unscrew the filter by hand.
Tip:
Wrap a paper towel around the filter wrench for a better grip and to prevent the filter from slipping.
Step 6: Clean the Oil Drain Plug and Filter Housing
Before reinstalling the drain plug, wipe off any dirt or debris from the drain plug and the surrounding area. Ensure the oil drain plug is clean and free from any obstructions that could prevent it from sealing properly.
Similarly, clean the oil filter housing with a rag or paper towel to remove any old oil or gasket residue. This ensures a clean surface for the new oil filter.
Step 7: Install the New Oil Filter
Take the new oil filter and lightly lubricate the sealing gasket with a small amount of fresh engine oil. This helps ensure a tight seal and prevents leaks. Thread the new filter onto the filter housing by hand until it is snug. Do not overtighten the filter.
Step 8: Reinstall the Drain Plug
Screw the drain plug back into place and tighten it securely. Be careful not to overtighten it, as this could damage the threads. Wipe off any excess oil that has spilled onto the engine or surrounding area.
Step 9: Add New Oil
Use the funnel to slowly pour the correct amount of fresh engine oil into the oil fill cap opening. Check your owner’s manual for the exact amount of oil needed for your mower.
Tip:
When adding oil, fill the engine until it reaches the “full” mark on the dipstick.
Step 10: Start the Engine and Check for Leaks
Start the engine and let it run for a few minutes. This allows the oil to circulate throughout the engine. While the engine is running, check for any leaks from the oil drain plug or the oil filter.
Step 11: Dispose of Old Oil Properly
Do not pour used engine oil down the drain or into the trash. It is harmful to the environment and can contaminate water sources. Dispose of old oil properly by taking it to a local recycling center or automotive parts store.
Step 12: Keep a Record of Your Oil Change
After completing the oil change, mark down the date and mileage in your maintenance log. This will help you keep track of when your next oil change is due.
Conclusion: Maintaining Your Mower’s Engine
Changing the oil in your riding lawnmower is a straightforward task that can help extend its life and performance. By following these steps and using the right tools and materials, you can ensure a successful oil change. Remember to check your owner’s manual for specific instructions and recommendations for your mower model. With regular oil changes, you’ll be able to enjoy a smooth and trouble-free mowing experience for years to come.
