Synthetic/organic blend assures excellent low-temperature properties for quicker starts
Provides maximum protection in severe, high RPM applications
Marine engines typically operate at higher RPM applications engines, requiring an oil that is specifically designed and formulated to provide protection under these higher temperature, higher stress circumstances
Marine engines have vertical crankshafts versus horizontal crankshafts in automotive engines. As a result, while an automotive engine’s crankshaft is not, so it needs an entirely different oil formula for maximum protection
Marine engines are often 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.
