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. |
