What kind of oil for a 20HP Briggs and Stratton lawn tractor?
Briggs and Stratton engines typically require SAE 30 oil, especially for older models or those operating in warmer climates. For newer Briggs and Stratton engines or operating in colder climates, a synthetic 5W-30 oil is recommended. However, it's always best to refer to the owner's manual or contact Briggs and Stratton customer support for the specific recommended oil type for your 20HP Briggs and Stratton lawn tractor to ensure optimal performance and protection of your engine.
