Short Overview: Changing the oil in your Briggs and Stratton lawn mower is a simple task that can extend the life of your engine. The process involves draining the old oil, replacing the oil filter, and filling the engine with fresh oil. By following the steps outlined in this article, you can ensure your lawn mower runs smoothly and efficiently for years to come.
Gather Your Supplies:
Before you dive into changing your lawn mower’s oil, ensure you have all the necessary tools and supplies. These are essential for a smooth and successful oil change:
- Briggs and Stratton Oil: Briggs and Stratton recommends using their own brand of oil, specifically designed for their engines. The type of oil you need will depend on the weather conditions in your area. For hot climates, use SAE 30 oil. For cooler climates, use SAE 5W-30 oil.
- Oil Filter: The oil filter is a crucial component in your lawn mower’s engine. It traps contaminants and prevents them from circulating in the engine oil. You can find Briggs and Stratton-specific oil filters at most hardware stores or online.
- Oil Drain Pan: This pan will collect the old engine oil when you drain it. A plastic or metal pan with a capacity of at least a quart is sufficient.
- Wrench: Use a wrench that fits the oil drain plug on your lawn mower. Most Briggs and Stratton engines use a 1/2-inch wrench.
- Gloves: Protect your hands from oil and grime by wearing a pair of work gloves.
- Rag or Shop Towel: You’ll need these to clean up any spills and wipe off the oil drain plug.
- Funnel: A funnel helps prevent spills when pouring the new oil into the engine.
Safety First:
Before you begin changing your lawn mower’s oil, it’s essential to take safety precautions to prevent injury.
Prepare Your Work Area:
- Choose a flat, stable surface. A concrete driveway or garage floor is ideal.
- Make sure the area is well-ventilated. Avoid changing the oil in a confined space without proper ventilation.
Ensure Your Lawn Mower is Cool:
- Let the engine cool completely. A hot engine can cause burns, and hot oil can splatter.
- Never change the oil when the engine is running.
Wear Protective Gear:
- Always wear eye protection. Oil can splash and cause irritation.
- Wear gloves. Oil can cause skin irritation and damage.
Properly Dispose of Used Oil:
- Never pour used oil down the drain. It contaminates the environment.
- Dispose of used oil responsibly. Most auto parts stores, recycling centers, or local government agencies offer used oil disposal services.
Step-by-Step Guide to Changing Your Lawn Mower Oil:
Now that you have gathered your supplies and taken the necessary safety precautions, you can begin changing your lawn mower’s oil. Here’s a detailed guide:
Step 1: Locate the Oil Drain Plug:
The oil drain plug is typically located on the bottom of the engine, near the oil pan. It’s usually a hexagonal-shaped plug with a threaded hole.
Step 2: Position the Oil Drain Pan:
Place the oil drain pan directly underneath the oil drain plug to catch the used oil as you drain it.
Step 3: Loosen the Oil Drain Plug:
Use the wrench to loosen the oil drain plug. Be careful not to overtighten it when you re-install it.
Step 4: Drain the Old Oil:
Allow the old oil to drain completely into the oil drain pan. This may take a few minutes.
Step 5: Reinstall the Oil Drain Plug:
Once the oil has drained, wipe the oil drain plug and reinstall it. Make sure it’s securely tightened.
Step 6: Locate the Oil Filter:
The oil filter is usually located near the top of the engine, typically attached to the engine block. It’s a cylindrical metal container with a gasket.
Step 7: Remove the Old Oil Filter:
Use your hands to loosen the oil filter. You may need to use a filter wrench if it’s difficult to loosen.
Step 8: Install the New Oil Filter:
Before installing the new oil filter, lightly coat the gasket with fresh oil. This helps ensure a good seal. Hand-tighten the new filter until it’s snug. Do not overtighten.
Step 9: Fill the Engine with New Oil:
Carefully pour the new oil into the engine’s oil fill cap, using a funnel to avoid spills. Refer to your lawn mower’s manual for the exact amount of oil required.
Step 10: Check the Oil Level:
After adding the new oil, check the oil level with the dipstick. The oil level should be between the “full” and “low” marks on the dipstick.
Step 11: Clean Up:
Wipe up any spills or drips with a rag or shop towel. Dispose of the used oil and oil filter properly.
Step 12: Start the Engine:
Start the engine and let it run for a few minutes to ensure that oil circulates properly.
Step 13: Check for Leaks:
Inspect the oil drain plug and oil filter for leaks. If you notice any leaks, tighten the oil drain plug or oil filter as needed.
Troubleshooting Common Problems:
Oil Filter Won’t Loosen:
- Use a filter wrench: If you can’t loosen the oil filter by hand, use a filter wrench.
- Apply penetrating oil: If the filter is stuck, spray penetrating oil around the filter’s base and let it sit for a few minutes.
Oil Drain Plug Won’t Loosen:
- Use a larger wrench: Try using a larger wrench to get a better grip on the oil drain plug.
- Apply penetrating oil: If the drain plug is stuck, spray penetrating oil around the drain plug and let it sit for a few minutes.
Oil Level is Low:
- Check for leaks: If the oil level is low, check for leaks around the oil drain plug, oil filter, or oil fill cap.
- Add more oil: If you don’t find any leaks, add more oil to the engine.
Tips for Maintaining Your Lawn Mower:
- Change the oil regularly: Change the oil every 25 hours of operation or once a season, whichever comes first.
- Use the correct type of oil: Use the type of oil recommended by Briggs and Stratton for your lawn mower.
- Keep the air filter clean: A clean air filter ensures optimal engine performance.
- Inspect the spark plug: Replace a worn or fouled spark plug for optimal ignition.
Conclusion:
Changing the oil in your Briggs and Stratton lawn mower is a simple and essential maintenance task. By following the steps outlined in this article, you can keep your mower running smoothly and efficiently for years to come. Remember to take safety precautions, gather your necessary tools, and dispose of used oil responsibly. With proper care and maintenance, your lawn mower will continue to provide years of reliable service, keeping your lawn looking its best.
FAQ
What type of oil should I use for my Briggs and Stratton lawn mower?
You should use oil that is specifically designed for small engines. Look for oil that meets the API service classification of “SJ” or higher. Most manufacturers recommend using 10W-30 oil for year-round use, but consult your mower’s owner’s manual for the specific oil recommendation for your model.
Using the correct type of oil is crucial for your mower’s performance and longevity. The wrong oil can lead to engine damage, reduced power, and increased wear.
How often should I change the oil in my Briggs and Stratton lawn mower?
The general recommendation is to change the oil every 25 hours of use or at least once per season. However, it is always best to check your owner’s manual for the recommended oil change intervals for your specific model.
Keeping up with regular oil changes is vital for the health of your lawn mower. Fresh oil ensures proper lubrication, reduces friction, and helps prevent engine wear and tear.
What tools do I need to change the oil in my Briggs and Stratton lawn mower?
You will need a few basic tools to change the oil in your lawn mower. These include:

What happens if I don’t change the oil in my Briggs and Stratton lawn mower?
Failing to change the oil in your lawn mower regularly can lead to several problems, including:
- Engine damage: Old oil becomes thick and sludgy, reducing its ability to lubricate engine parts effectively. This can cause friction, wear and tear, and ultimately engine failure.
- Reduced performance: A dirty engine will not run as smoothly or efficiently as a clean one. This can lead to decreased power, poor starting, and even stalling.
- Increased emissions: A clogged engine will burn more fuel and produce more harmful emissions.
Regular oil changes are essential for keeping your lawn mower running smoothly and efficiently.
