AMSOIL 25W-40 Synthetic-Blend Marine Engine Oil



NMMAProtects Against Wear
Marine engines operate under high loads and rpm for extended periods. On average, a marine engine powering a boat 48 kph runs at about 5,000 rpm. In contrast, an automotive engine powering a car 96 kph runs at about 2,000 rpm. Higher stress causes traditional automotive oils to break down and lose viscosity. AMSOIL 25W-40 Synthetic Blend 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 25W-40 Synthetic Blend Marine Engine Oil is fortified with potent inhibitors that guard against damaging rust and corrosion.

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

    Great oil!
    By  JEFF,  a  Verified Buyer  from  Highlands Ranch, CO  on  November 01, 2021
    We've used this oil in our previous boat and our current boat. Our old boat had the 4.3 V6 in it and the new one has the Mercruiser 4.5 V6. We've never had any engine issues with either boat. They both had good oil pressure with no engine noise aside from the expected. Even after it sits for a while I've never heard any lifter noise or anything like that when I first fire it up.
    Bottom Line
    Yes, I would recommend this to a friend.
