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. |
