Description
If you’re running a large-displacement, air-cooled engine at the track or in high-performance street duty, you need oil that can handle sustained heat without breaking down. S&S Cycle’s 20W-50 synthetic formulation is engineered specifically for these extreme conditions, with enhanced moly content and elevated zinc/phosphorous additives that reduce friction and protect critical engine components under stress. This is the oil choice for riders and builders who refuse to compromise on engine longevity.
