AMSOIL 10W40 Synthetic Marine Engine Oil

Description

AMSOIL Synthetic 10W40 Marine Oil is engineered to deliver enhanced performance, protection, and reliability tailored specifically for high-performance marine engines. Utilizing advanced synthetic base oils, it resists viscosity loss caused by mechanical shear, maintaining a strong lubricating film that effectively protects vital engine components even under extreme high-heat and high-rpm conditions where conventional oils typically degrade.

Formulated with potent anti-wear additives, this marine oil reduces friction and metal-to-metal contact, preserving engine compression and maximizing power output and engine longevity. Superior rust and corrosion inhibitors ensure protection not only during operation but also during inactivity and long-term storage, preventing oxidation and corrosion damage.

Certified by the National Marine Manufacturers Association (NMMA) with FC-W Catalyst Compatible status, AMSOIL 10W40 Synthetic Marine Oil meets rigorous performance standards for four-stroke outboard motors. It is compatible with a broad array of marine engines including those from Honda, Mercury, Yamaha, Suzuki, and others. This oil supports extended service intervals in many applications, reducing maintenance needs while remaining fully Warranty Secure.

Compared to conventional marine oils, AMSOIL’s synthetic formulation excels with superior resistance to thermal and mechanical breakdown, retaining optimal thickness and protective qualities longer. It performs best when used alone and is compatible with both synthetic and conventional oils. Aftermarket additives are not recommended.

Ideal for dedicated anglers and boating enthusiasts who demand peak engine protection and performance under demanding conditions, AMSOIL Synthetic 10W40 Marine Oil ensures peace of mind on every outing.
