The rumble of a lawn mower engine is a familiar summer soundtrack, but that symphony can quickly turn sour if you’re not giving your engine the lubrication it needs. A Briggs & Stratton engine, a popular choice for lawn mowers, relies on regular oil changes to keep it running smoothly and prevent costly repairs. But the process of adding oil can seem daunting for first-timers. This comprehensive guide will walk you through the steps, ensuring you can confidently maintain your lawn mower and keep your yard looking pristine.
In this article, we’ll cover everything from identifying the right type of oil for your mower to the proper technique for changing the oil. We’ll also address common concerns and provide helpful tips to ensure you get the most out of your Briggs & Stratton engine.
What Kind of Oil Do I Need?
The type of oil your Briggs & Stratton engine requires is crucial. You’ll find this information printed on the engine’s dipstick, owner’s manual, or an identification plate located on the engine. Briggs & Stratton engines generally use SAE 30 oil in warmer climates and SAE 5W-30 oil for colder weather.
Step-by-Step Guide to Changing the Oil:
1. Preparing Your Mower:
- Safety First: Always disconnect the spark plug wire before starting any work on the engine. This prevents accidental ignition and potential injury.
- Warm Up the Engine: A warm engine allows for easier oil drainage and ensures better oil flow. Run the mower for a few minutes before proceeding.
- Finding the Oil Drain Plug: Locate the oil drain plug, typically found on the bottom of the engine.
2. Draining the Old Oil:
- Prepare a Container: Place a suitable container (a drain pan or a jar) underneath the drain plug to catch the old oil.
- Unscrew the Plug: Use a wrench or socket to loosen and remove the drain plug. Be cautious not to drop the plug into the container.
- Let it Drain: Allow the old oil to drain completely into the container. This might take a few minutes.
3. Replacing the Drain Plug:
- Clean the Plug: Wipe the drain plug with a clean cloth to remove any debris before reinstalling it.
- Tighten Securely: Use a wrench to tighten the drain plug to the correct torque. Overtightening can damage the plug and engine.
4. Filling with Fresh Oil:
- Locate the Oil Fill Cap: Find the oil fill cap, usually marked with a “dipstick” symbol.
- Add Oil Slowly: Pour fresh oil into the fill hole until the oil level reaches the “Full” mark on the dipstick.
- Double-Check: Remove the dipstick and wipe it clean. Reinsert it fully and then remove it to check the oil level. Add more oil if needed to reach the “Full” mark.
- Replace the Cap: Securely tighten the oil fill cap.
5. Restarting the Engine:
- Reconnect the Spark Plug Wire.
- Start the Engine: Run the engine for a few minutes to ensure proper oil circulation.
Tips for Success:
- Regular Oil Changes: Changing the oil every 25 hours of operation or once a year, whichever comes first, is crucial for maintaining optimal engine performance.
- Use the Right Oil: Refer to your mower’s manual or the identification plate for the recommended oil type and viscosity.
- Clean Your Mower: Wipe away any spills or drips and dispose of used oil responsibly.
- Store Oil Properly: Always store oil in a tightly sealed container in a cool, dry place.
Troubleshooting Tips:
- Engine Won’t Start: If your engine won’t start after an oil change, double-check that you’ve reconnected the spark plug wire and that there’s no oil spill around the spark plug.
- Oil Leaks: Check for loose drain plugs or overfilled oil levels. If you continue to experience leaks, consult a qualified mechanic.
- Excessive Smoke: Black or blue smoke coming from the exhaust can indicate engine problems related to oil consumption. Consult a mechanic for diagnosis.
Conclusion:
Changing the oil in your Briggs & Stratton lawn mower is a simple task that can save you time and money in the long run. By following these steps and keeping a regular maintenance schedule, you can ensure your mower runs smoothly and efficiently for years to come. Remember, a well-maintained engine means a well-maintained lawn.
Frequently Asked Questions
How Much Oil Do I Need?
The amount of oil your Briggs & Stratton lawnmower needs will vary depending on the model. You can find the recommended oil capacity in your owner’s manual. Typically, you’ll need between 16 and 20 ounces of oil. Be sure to only fill the oil tank to the “full” line, never overfill it.
Overfilling the oil tank can cause serious engine damage, as excess oil can be forced into the combustion chamber, leading to a loss of power and potential damage to the engine. Always check the oil level before starting your lawnmower and top it off as needed.
What Type of Oil Should I Use?
Briggs & Stratton recommends using a high-quality oil specifically designed for small engines. Look for an oil with a viscosity rating of SAE 30 or SAE 5W-30. You can find these types of oils at most hardware stores and home improvement centers. Always refer to your owner’s manual for the specific type of oil recommended for your model.
Using the correct oil is crucial for the long-term health of your lawnmower’s engine. The wrong oil can lead to increased wear and tear, engine damage, and reduced performance.
Where Do I Put the Oil?
The oil fill cap is usually located on the side of the engine, near the top. It will be marked with an oil can symbol. Unscrew the cap and carefully pour the oil into the filler neck. Ensure the oil flows freely and avoid spilling it on the engine.
It’s important to note that different models might have slightly different locations for the oil fill cap. Consult your owner’s manual for precise instructions regarding the location and type of oil fill cap on your specific model.
How Often Should I Change the Oil?
You should change the oil in your Briggs & Stratton lawnmower every 25 hours of use or at the beginning of each mowing season, whichever comes first. Regularly changing the oil helps keep your engine running smoothly and prevents premature wear.
Check your owner’s manual for specific recommendations for your model, as the frequency of oil changes may vary depending on the engine size and operating conditions.
What Happens if I Don’t Change the Oil?
If you don’t change the oil regularly, it will eventually become contaminated with dirt, debris, and metal shavings from the engine. This contaminated oil will lose its ability to lubricate the engine parts effectively, leading to increased friction, wear and tear, and potential engine damage.
In the worst-case scenario, a severely neglected oil change can cause your engine to seize up completely, requiring costly repairs or even replacement.
Can I Use Synthetic Oil?
Yes, you can use synthetic oil in your Briggs & Stratton lawnmower. Synthetic oils offer several advantages over conventional oils, including better high-temperature performance, extended oil change intervals, and increased engine protection.
However, it is always best to consult your owner’s manual for specific recommendations on the type of oil, including synthetic oil, that is compatible with your model.
Is There Anything Else I Need to Know?
After adding oil, make sure to wipe up any spills and tighten the oil fill cap securely. You can also check the oil level again after running the engine for a few minutes to ensure there are no leaks.
Additionally, it is important to check the condition of your oil filter. The oil filter should be changed every two oil changes, or according to the recommendations in your owner’s manual. A clean oil filter helps to keep your engine clean and running smoothly.
