Briggs and Stratton is a well-known brand in the lawn mower industry, producing reliable and durable small engines. Choosing the right oil for your Briggs and Stratton lawn mower is crucial for maintaining engine performance, longevity, and smooth operation. This article provides a detailed guide on selecting the best oil for your mower, including viscosity grades, oil types, and maintenance tips.
Understanding Briggs and Stratton Oil Requirements
Briggs and Stratton engines are designed to run on specific types of oil to ensure optimal performance. The company recommends using high-quality detergent oils classified as API Service Class SJ or higher. These oils help reduce engine wear, prevent sludge buildup, and maintain cleanliness inside the engine.
The two main factors to consider when choosing oil are viscosity grade and oil type (conventional or synthetic). Following the manufacturer’s recommendations ensures your mower runs smoothly in different weather conditions.
Recommended Oil Viscosity for Briggs and Stratton Lawn Mowers
Viscosity refers to the oil’s thickness and its ability to flow at different temperatures. Briggs and Stratton provides clear guidelines on which viscosity to use based on the operating temperature:
SAE 30
This is the most common oil for Briggs and Stratton mowers and works best in temperatures above 40°F (4°C). It provides excellent lubrication in warm weather but may become too thick in colder conditions.
10W-30
A multi-viscosity oil suitable for varying temperatures. It flows well in cold weather (below 40°F) while maintaining proper lubrication in warmer conditions. Ideal for seasonal use.
5W-30
Best for extremely cold climates, as it remains fluid in freezing temperatures. If you start your mower in winter or early spring, this oil ensures smooth engine cranking.
Synthetic 5W-30 or 10W-30
Synthetic oils offer superior protection, especially in extreme temperatures. They resist breakdown better than conventional oils and extend engine life.
Always check your mower’s manual for the exact viscosity recommendation, as some newer models may have specific requirements.
Conventional vs. Synthetic Oil for Briggs and Stratton Mowers
Both conventional and synthetic oils have advantages, and the best choice depends on your usage and climate.
Conventional Oil
This is a standard mineral-based oil suitable for most Briggs and Stratton engines. It is cost-effective and works well under normal operating conditions. However, it breaks down faster under high heat or heavy use.
Synthetic Oil
Made from chemically modified petroleum compounds, synthetic oil provides better engine protection, especially in extreme temperatures. It reduces friction, resists sludge formation, and lasts longer between changes. While more expensive, it is a great choice for commercial use or harsh conditions.
Synthetic Blend
A mix of conventional and synthetic oils, offering some benefits of synthetic at a lower cost. A good middle-ground option for homeowners who want enhanced protection without the full price of synthetic.
Importance of Using the Right Oil in Your Lawn Mower
Using the correct oil in your Briggs and Stratton mower ensures:
Engine Longevity: Proper lubrication reduces friction between moving parts, preventing premature wear.
Optimal Performance: The right viscosity ensures smooth engine operation, whether in hot summers or cold springs.
Fuel Efficiency: Well-lubricated engines run more efficiently, saving fuel over time.
Reduced Deposits: High-quality detergent oils keep the engine clean by preventing sludge and carbon buildup.
Warranty Compliance: Using the recommended oil helps maintain your engine’s warranty coverage.
How Often Should You Change the Oil in a Briggs and Stratton Mower?
Regular oil changes are essential for engine health. Briggs and Stratton recommends the following intervals:
First Oil Change: After the first 5 hours of use (for new mowers). This removes any metal particles from engine break-in.
Subsequent Changes: Every 50 hours of operation or at least once per mowing season. If you use the mower heavily, consider changing it more frequently.
Before Storage: If storing the mower for an extended period, change the oil to prevent acidic buildup from old oil.
Steps to Change Oil in a Briggs and Stratton Lawn Mower
Changing the oil is a simple maintenance task that can be done at home:
Warm Up the Engine: Run the mower for a few minutes to warm the oil, making it easier to drain.
Turn Off and Tilt: Shut off the engine and tilt the mower (with the air filter facing up) to access the drain plug.
Drain the Oil: Place a container under the drain plug, remove the plug, and let the oil drain completely.
Replace the Plug: Once drained, reinstall the drain plug securely.
Add Fresh Oil: Use a funnel to pour the recommended oil type and amount into the fill tube. Check the dipstick to ensure proper levels.
Dispose of Old Oil Properly: Take used oil to a recycling center or auto parts store that accepts it.
Common Mistakes to Avoid When Choosing Lawn Mower Oil
Using Automotive Oil: Car oils often contain additives that can harm small engines. Always use oil designed for lawn mowers.
Ignoring Viscosity Recommendations: Thicker or thinner oil than recommended can lead to poor lubrication or overheating.
Overfilling or Underfilling: Too much oil can cause leaks and engine damage, while too little leads to insufficient lubrication.
Using Dirty or Old Oil: Contaminated oil loses its lubricating properties and should be changed promptly.
Best Oil Brands for Briggs and Stratton Lawn Mowers
While Briggs and Stratton sells its own branded oil, other high-quality options include:
Mobil 1: Known for excellent synthetic oils that enhance engine performance.
Valvoline: Offers both conventional and synthetic oils suitable for small engines.
Castrol: Provides reliable lubrication for lawn mower engines.
Shell Rotella: A trusted brand with strong detergent properties to keep engines clean.
Conclusion
Choosing the right oil for your Briggs and Stratton lawn mower is essential for maintaining engine efficiency and durability. Always refer to the owner’s manual for specific recommendations on viscosity and oil type. Regular oil changes, proper maintenance, and avoiding common mistakes will keep your mower running smoothly for years. Whether you prefer conventional or synthetic oil, ensuring it meets the required API standards will help protect your engine and maximize performance.
By following these guidelines, you can extend the life of your Briggs and Stratton mower and enjoy a well-maintained lawn season after season.
