BEFORE YOU OPERATE LUBRICATING OIL The choice of lubricating oil is very important. If an unsuitable oil is used, or an oil change is neglected, it may result in damage and reduce the life of the Sail-Drive. When selecting a lubricating oil, use one of the following: Lubricating Oil Chart Use only oil of quality GL-4 or GL-5 in the API service, and SAE No. 90 or 80W90.
