AMSOIL Synthetic Marine Engine Oil is a premium synthetic formulation designed for ultra heat and stress of high-rpm operation and provides outstanding wear protection. It prevents rust and corrosion while the engine sits idle and is stored long-term to keep the engine protected, even when it’s not running. AMSOIL Synthetic Marine Engine Oil provides perfect protection for hardcore anglers and boating enthusiasts who demand the best for their marine engines.
AMSOIL Synthetic Marine Engine Oil’s naturally strong base oils resist viscosity loss due to mechanical shear. It develops a tough lubricating film that protects engine parts, even in high-heat, high-rpm conditions that break down other oils. AMSOIL Marine 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 engine life. Contains strong anti-wear additives that actually serve to lower wear between metal-to-metal contact areas, protecting against compression loss for maximum power and engine life.
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.
AMSOIL Synthetic Marine Engine Oil is certified by the National Marine Manufacturers Association (NMMA) for use in four-stroke outboard motors.
