Universal Synthetic Marine Gear Lube SAE
75W/80W-90
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 anti-wear 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, as seen in the graph.

AMSOIL Universal Synthetic Marine gear Lube is compatible
with other commercially available conventional and synthetic
marine gear lubes.
Follow manufacturers recommended service
intervals.
It is generally a good idea to change
gear lube at the end of the season prior to storage.
