Performance Benefits

Outboards are constantly under load, dealing with changing RPM and regular exposure to moisture. This full synthetic marine formula helps maintain consistent viscosity under those conditions while providing a durable protective film across internal engine components. The result is smoother operation, dependable performance, and added confidence whether you're putting in long hours or letting the engine sit between uses.
