Synthetic Marine Gear Oil SAE 75W90 - 80W90
High Performance Synthetic Marine Gear Oil Engineered to
Meet the Severe Demands of Boating Applications
-
Excellent Gear and Bearing Protection even when contaminated with 10% water
- Reduced Friction and Wear
- Excellent Rust and Corrosion Protection
- Long Seal Life
- Superior Foam Prevention
PRODUCT DESCRIPTION
AMSOIL Universal Synthetic Marine Gear Lube is an exclusive AMSOIL formulation of synthetic base oils and high performance additives that address the specific concerns of marine applications. It is extreme pressure (EP) additive fortified for superior protection of fast accelerating, high torque/horsepower engines. It protects against shock loading from cavitation of heavily loaded engines.
AMSOIL Universal Synthetic Marine Gear Lube is water resistant. It maintains extreme pressure protection even when contaminated with as much as 10% water. It promotes longer seal life, preventing excessive water leakage. AMSOIL Universal Synthetic Marine Gear Lube protects against rust and is compatible with aluminum, copper and brass alloys.
APPLICATIONS
AMSOIL Universal Synthetic Marine Gear Lube is recommended for fresh and salt water applications requiring either 75W-90 or 80W-90 viscosity grade and meeting either API GL-4 or GL-5 performance standards.

Marine gear oils operate in environments subject to water contamination. The chart below demonstrates the ability of AMSOIL Universal Synthetic Marine Gear Lube to maintain designed qualities such as extreme pressure/anti-wear performance and resistance to foaming, even when subjected to 10% water contamination.
The Falex Procedure is measurement of a gear lube's extreme pressure and antiwear properties. A high value in the Falex Extreme Pressure Test relates to extra extreme pressure protection. AMSOIL Universal Synthetic Marine Gear Lube is not affected by water and provides 50% more extreme pressure protection for long gear and bearing life.
The presence of foam in a lubricant disrupts 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 Universal Synthetic Marine Gear Lube. Other conventional gear lubes can foam when mixed with water.
