Understanding Engine Oil Requirements
Briggs & Stratton mowers typically use SAE 30, SAE 30 synthetic blend, or 10W-30 oils, depending on the model and season. Engine oil serves as both a lubricant and a coolant, reducing friction between moving parts and dissipating heat. Using the wrong viscosity or oil type can lead to increased wear, sludge buildup, and inefficient combustion.
Key Factors When Selecting Oil
- Viscosity Rating: Match the oil’s viscosity to your mower’s engine manual. SAE 30 is common in older models, while 10W-30 is preferred for modern engines due to better cold-start protection and thermal stability.
- Oil Type: Synthetic blends offer superior protection against oxidation and extreme temperatures compared to conventional oils, especially in harsh conditions.
- Additives: Look for oils with detergents and anti-wear additives to clean engine deposits and protect metal surfaces.
- Seasonal Needs: Use lighter oils in colder months for easier starts and heavier oils in hot weather for better lubrication.
