Provides maximum protection in severe, high rpm applications
Marine engines typically operate at higher rpms than automotive engines, requiring an oil that is specifically designed
and formulated to provide protection under these higher temperature, higher stress circumstances
Marine engines have vertical crankshaft s versus horizontal crankshaft s in automotive engines. As a result, while an automotive
engine’s crankshaft is continuously bathed in oil,the marine engine’s crankshaft is not, so it needs an entirely different oil
formula for maximum protection
Marine engines are oft en operated in harsh, saltwater environments that are much more demanding than the conditions
faced by most automotive engines. Accordingly, their engine oil must be up to the task
