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.
