AMSOIL Synthetic Marine Engine Oil is an excellent synthetic formulation designed to withstand the heat and stress of high-rpm operation and to provide excellent wear protection. It protects against rust and corrosion during periods of inactivity and long-term storage to protect your engine even when it is not running. Synthetic Marine Engine Oil is ideal for hardcore anglers and boating enthusiasts who demand the best protection for their marine engines.
Fights engine wear
The naturally strong base oils of AMSOIL Synthetic Marine Engine Oil resist viscosity loss due to mechanical shear. The oil develops a tough lubricating film that protects engine parts, even in the high-temperature, high-rpm conditions that break down other oils. Synthetic Marine Engine Oil contains powerful anti-wear additives that further reduce wear in metal-to-metal contact areas, protecting against compression loss for maximum power and extending the life of marine engines.
Excellent anti-rust performance
Good rust protection does not come naturally to a motor oil; it only comes by design. AMSOIL synthetic engine oil is fortified with powerful inhibitors that protect against destructive rust and corrosion. It protects engines during use and during periods of inactivity or long-term storage.
Excellent resistance to high stress and high rpm
Increased protection against rust and corrosion

SERVICE LIFE
Four-stroke outboard engines and personal watercraft applications watercraft: Due to possible fuel dilution or water contamination, change the oil at the interval recommended by the engine or boat manufacturer.
Inboard and sterndrive applications: Change the oil at 2X the interval recommended by the engine manufacturer or one year, whichever comes first.
Compatibility
AMSOIL Synthetic Marine Engine Oil is compatible with other synthetic and conventional engine oils. However, adding other oils will reduce the service life and performance benefits of AMSOIL engine oils. AMSOIL Synthetic Marine Engine Oil does not support extended drain intervals where oils have been mixed. Aftermarket oil additives are not recommended for use with AMSOIL lubricants.
