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. |
