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.
