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
prevents 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.
