10W-30 Synthetic Formula 4-Stroke Marine Oil

AMSOIL 10W-30 Synthetic 4-Stroke Marine Oil is specially formulated for marine engines, delivering outstanding wear protection, excellent viscosity stability, low volatility, and superior rust prevention. It is certified by NMMA FC-W and Warranty Certified for use in 4-stroke outboard engines, inboard engines, and general marine engines.

Benefits

NMMA Certification
AMSOIL 4-Stroke Synthetic Marine Oil is certified by the National Marine Manufacturers Association (NMMA) and meets the stringent NMMA FC-W Catalyst Compatible specification. Its NMMA registration number is #FC-00833T 10W-30.

Superior Wear Protection
Marine engines typically operate under high loads and at high RPM for extended periods, which can cause conventional oils to break down and lose viscosity. AMSOIL 4-Stroke Synthetic Marine Oil is engineered to withstand high heat and maintain a strong protective film on engine surfaces, reducing wear and extending engine life.

Rust and Corrosion Protection
Marine engines are highly prone to rust, which leads to accelerated wear and damage. AMSOIL 4-Stroke Synthetic Marine Oil contains superior anti-rust additives and has passed rigorous NMMA and FC-W Catalyst Compatible tests to ensure top-tier corrosion protection.

Compatibility with Other Oils
