Can a 5w-30 work in Briggs 12 hp motor?

Yes, a 5W-30 oil can work in a Briggs & Stratton 12 hp motor, especially in cooler temperatures, as it provides good lubrication and flow. However, it's essential to check the owner's manual for the manufacturer's recommended oil viscosity, as Briggs & Stratton typically suggests using 30-weight oil for warmer conditions. Using the correct oil ensures optimal performance and longevity of the engine. Always prioritize the specifications provided by the manufacturer for best results.
