Frequently Asked Questions
What type of oil should I use in my Briggs and Stratton lawn mower engine?
The type of oil you should use in your Briggs and Stratton lawn mower engine depends on the specific model and operating conditions. Consult your owner’s manual for the recommended oil viscosity and type. Generally, Briggs and Stratton recommends using a high-quality, detergent-based oil with an API rating of SF, SG, SH, SJ, or higher.
It is important to use the correct oil viscosity, as this affects the engine’s performance and longevity. For example, a thicker oil may be suitable for colder temperatures, while a thinner oil may be better for hot weather. Always use the recommended oil type and viscosity for your specific lawn mower engine.
What is the difference between SAE 30 and SAE 10W-30 oil?
SAE 30 oil is a single-grade oil that is suitable for a narrow range of temperatures. SAE 10W-30 oil is a multi-grade oil that can be used in a wider range of temperatures. The “W” in 10W-30 stands for “winter,” and the numbers indicate the oil’s viscosity at different temperatures.
SAE 10W-30 oil will flow more easily in cold weather than SAE 30 oil. This is because it is thinner at lower temperatures. In hot weather, SAE 10W-30 oil will be thicker than SAE 30 oil. This means it will provide better protection for your engine at high temperatures.
