Here's why:
* SAE 30 is a common viscosity for small gasoline engines, offering good protection and lubrication in a range of conditions.
* Briggs & Stratton recommends using SAE 30 for most of their 6 hp engines.
* Viscosity refers to the thickness of the oil. You'll need a thicker oil (like SAE 30) in warmer temperatures to prevent it from becoming too thin and losing its protective properties.
Important considerations:
* Check your engine's manual: Always consult the specific owner's manual for your Briggs & Stratton 6 hp engine. It may contain specific recommendations regarding oil type, viscosity, and other maintenance procedures.
* Operating temperature: If you live in a very cold climate, you might need to use a thinner oil (like SAE 10W-30 or 5W-30) during the colder months.
* Oil quality: Use a high-quality oil that meets the specifications outlined in your engine's manual.
Never use automotive oil in a small engine. Automotive oil is designed for higher-performance engines and can cause problems in small engines, such as clogging oil passages or causing excessive wear.
