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. |
