Description

AMSOIL Synthetic Blend 25W40 Marine Oil

25W40 Marine Oil from AMSOIL is a synthetic marine engine oil that guards against wear while delivering excellent protection against rust and corrosion. Marine engines operate under high loads and rpm for extended periods. On average, a marine engine powering a boat at 30 mph runs at about 5,000 rpm. In contrast, an automotive engine powering a car at 60 mph runs at about 2,000 rpm. Higher stress causes traditional automotive oils to break down and lose viscosity. AMSOIL 25W-40 Marine Engine Oil is designed with excellent shear stability to deliver a consistent lubricating film. It helps guard engine components from wear for maximum life.

Excellent Anti-Rust Performance
Marine engines are prone to rust and corrosion due to constant exposure to humid, wet environments. Rust on engine parts acts like sandpaper, scouring bearings, the cylinder wall, piston rings, and other components, while aluminum pistons and other parts can corrode. Rust and corrosion reduce engine power and eventually cause catastrophic failure.

Good rust protection is not natural to motor oil; it comes only by design. AMSOIL 25W40 Marine Oil is fortified with potent inhibitors that guard against damaging rust and corrosion.

• Excellent high-stress, high-rpm endurance
• Increased rust and corrosion protection
