Marine Gear Oil Specifics

AMSOIL Synthetic Marine Gear Lube 75W-90AMSOIL Synthetic Marine Gear Lube is an exclusive AMSOIL formulation of synthetic base oils and high-performance additives that addresses the specific concerns of marine applications. It is fortified with extreme-pressure (EP) additives for superior protection of fast-accelerating, high-torque/horsepower engines. It protects against shock loading from cavitation of heavily loaded engines.

AMSOIL Synthetic Marine Gear Lube is water resistant. It maintains extreme-pressure protection even when contaminated with as much as 10 percent water. It promotes longer seal life to help prevent water contamination. AMSOIL Synthetic Marine Gear Lube is designed to prevent rust and is compatible with aluminum, copper and brass alloys.

Outstanding anti-wear characteristics for harsh marine environment

Marine gear oils operate in environments subject to water contamination. The chart above demonstrates the ability of AMSOIL Synthetic Marine Gear Lube to maintain designed qualities such as extreme-pressure/anti-wear performance and resistance to foaming, even when subjected to 10 percent water contamination.

The Falex Procedure is a measurement of a gear lube’s extreme-pressure and anti-wear properties. A high value in the Falex Extreme-Pressure Test relates to extra extreme-pressure protection. AMSOIL Synthetic Marine Gear Lube provides extreme-pressure protection and is highly resistant to the effects of water contamination.

The presence of foam in a lubricant disrupts the oil film and promotes wear. Water contamination can increase the likelihood of foaming. Industry-standard testing demonstrates zero foam in both new and water-contaminated AMSOIL Synthetic Marine Gear Lube.

  • Excellent gear and bearing protection, even when contaminated with 10% water
  • Reduced friction and wear
  • Protection against rust and corrosion
  • Long seal life
  • Superior foam prevention

Excellent Volvo Penta oil

By  Trouper,  a  Verified Buyer  from  Syracuse, NY  on  November 18, 2023
This last summer was the first year with 100% Amsoil in the lower unit, I had been putting the last .2 qt in from a bottle of Lucas that met the required spec. This was also the first year I had zero shifting issues and it ran flawlessly all while sitting in wet slip for 6 months

Mercury and Yamaha

By  DANIEL,  a  Verified Buyer  from  Michigan   on  October 20, 2023
Put this in my buddies Mercury 115 the last three years and it’s cleaning up what ever was in it when he bought it used. My Yamahas only see Amsoil gear oil and it looks good each year for the change before winter sets in
