AMSOIL SAE 75W/80W-90 Synthetic Marine Gear Lube
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.
