Product Details
AMSOIL Synthetic Marine Engine Oil is a premium synthetic formulation designed to withstand the heat and stress of high-rpm operation and deliver excellent wear protection. It protects against rust and corrosion during periods of inactivity and long-term storage to keep your engine protected, even when it’s not running. Synthetic Marine Engine Oil is perfect for hardcore anglers and boating enthusiasts who demand the best protection for their marine engines.
Product Description
Fights Engine Wear
AMSOIL Synthetic Marine Engine Oil's naturally strong base oils resist viscosity loss due to mechanical shear. The oil develops a tough lubricating film that protects engine parts, even in high-heat, high-rpm conditions that breakdown other oils. Synthetic Ma-rine Engine Oil contains robust anti-wear additives that further reduce wear in metal-to-metal contact regions, guarding against compression loss for maximum power and extending the lives of marine engines.

Excellent Anti-Rust Performance
Good rust protection is not natural to motor oil; it comes only by design. AMSOIL Synthetic Marine Engine Oil is fortified with potent inhibitors that guard against damaging rust and corrosion. It protects engines during use and during inactivity or long-term storage.

- Excellent high-stress, high-rpm endurance
- Increased rust and corrosion protection
- NMMA FC-W Catalyst Compatible

Service Life

- Four-stroke outboard motors and personal watercraft applications: Due to potential fuel dilution or water contamination, change oil at the engine or watercraft manufacturer-recommended interval.
- Inboard and I/O applications: Change oil at two times the engine manufacturer recommended interval or one year, whichever comes first.

Compatibility
AMSOIL Synthetic Marine Engine Oil is compatible with other synthetic and conventional motor oils. Adding other oils, however, will shorten the life expectancy of AMSOIL motor oils and reduce their performance benfits. AMSOIL does not support extended drain intervals where oils have been mixed.

Aftermarket oil additives are not recommended for use with AMSOIL Synthetic Marine Engine oil.
