AMSOIL Synthetic Marine Gear Lube is an exclusive AMSOIL formulation of synthetic base oils and high-performance additives that addresses the specific concerns of marine applications. It is fortified with extreme-pressure (EP) additives for superior protection of fast-accelerating, high-torque/horsepower engines. It protects against shock loading from cavitation of heavily loaded engines.

AMSOIL Synthetic Marine Gear Lube delivers advanced outboard protection against power loss and gear wear, even with up to 15 percent water contamination.1 It promotes long seal life to help prevent water contamination. AMSOIL Synthetic Marine Gear Lube is designed to prevent rust and is compatible with aluminum, copper and brass alloys.

Marine gear oils operate in environments subject to water contamination. The Falex Procedure is a 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 Synthetic Marine Gear Lube provides extreme-pressure protection and is highly resistant to the effects of water contamination. The presence of foam in a lubricant disrupts the oil film and promotes wear. Water contamination can increase the likelihood of foam. Industry-standard testing demonstrates zero foam in both new and water-contaminated AMSOIL Synthetic Marine Gear Lube.
