Performance Benefits

Outboard engines operate differently than automotive engines, often running under steady load with frequent throttle changes and constant exposure to moisture. This full synthetic marine formula helps maintain consistent viscosity while delivering a durable protective film across internal components. The result is smoother operation and reliable protection during extended runs and high-demand use.
