Serious Wear Control For 4-Stroke Inboard, Outboard Or PWC Engines

Whether you operate at high RPM or troll all afternoon, AMSOIL 10W-30 Marine Synthetic Motor Oil is built to protect. It offers a 100% synthetic base oil that is loaded with anti-wear additives. AMSOIL 10W-30 will not thin out or shear down under high heat. It lowers friction to minimize heat generation and maximize efficiency. This 4-stroke marine 10w-30 oil can help keep your engine running its best for many seasons to come.

Maintains Your Engine WarrantyNMMA FC-W Catalyst Compatible Logo

AMSOIL 10W-30 Marine Synthetic Motor Oil surpasses the NMMA (National Marine Manufacturers Association) “FC-W” specification, so your warranty is safe and secure. AMSOIL Marine 10W-30’s NMMA Registration number is FC-00358P.

Serious Anti-Rust/Corrosion Protection

Regular car oil and lesser 4-stroke power sport oils may not contain rust and corrosion additives. AMSOIL 10W-30 Marine Oil is packed with anti-rust additives to protect your engine during the season and during long off-season storage periods.

Resists Oil Consumption

AMSOIL 10W-30 Marine Synthetic Motor Oil fights oil usage in hot operating temperatures due to its low volatility and shear stability.
