AMSOIL 10W-40 Synthetic Marine Engine Oil



Fights Engine Wear
AMSOIL Synthetic Marine Engine Oil's naturally strong base oils resist viscosity loss due to mechanical shear. The oil develops a tough lubricating film that protects engine parts, even in high-heat, high-rpm conditions that breakdown other oils. Synthetic Ma-rine Engine Oil contains robust anti-wear additives that further reduce wear in metal-to-metal contact regions, guarding against compression loss for maximum power and extending the lives of marine engines.

Excellent Anti-Rust Performance
Good rust protection is not natural to motor oil; it comes only by design. AMSOIL Synthetic Marine Engine Oil is fortified with potent inhibitors that guard against damaging rust and corrosion. It protects engines during use and during inactivity or long-term storage.

  • Excellent high-stress, high-rpm endurance
  • Increased rust and corrosion protection
  • NMMA FC-W Catalyst Compatible

Service Life

  • Four-stroke outboard motors and personal watercraft applications: Due to potential fuel dilution or water contamination, change oil at the engine or watercraft manufacturer-recommended interval.
  • Inboard and I/O applications: Change oil at two times the engine manufacturer recommended interval or one year, whichever comes first.

Compatibility
AMSOIL Synthetic Marine Engine Oil is compatible with other synthetic and conventional motor oils. Adding other oils, however, will shorten the life expectancy of AMSOIL motor oils and reduce their performance benfits. AMSOIL does not support extended drain intervals where oils have been mixed.

    I buy this marine-specific synthetic oil.
    By  James,  a  Verified Buyer  on  October 20, 2019
    I use this great lube oil for my 1990 Cruisers Esprit with twin Crusader 350's. I am never disappointed with this synthetic, even though they were designed for straight SAE 40. They run smooth and oil pressures are spot on.

    Improved power
    By  Vic,  a  Verified Buyer  from  Astor, Fl.  on  May 26, 2019
    I recently started using Amsoil Marine in our Yamaha Jet Boat. With the boat being 6 years old, I immediately notice a quieter ride and was most impressed by the 5-7% thrust improvement (3-5mph). We will be using it in our jet skis next

    Yes, I would recommend this to a friend.
