• API GL-4, GL-5

AMSOIL Synthetic Marine Gear Lube provides:

• Excellent gear and bearing protection even when contaminated with 10% water
• Reduced friction and wear
• Rust and corrosion protection
• Long seal life
• Superior foam prevention

Marine gear oils operate in environments subject to water contamination. The chart demonstrates the ability of AMSOIL Synthetic Marine Gear Lube to maintain designed qualities such as extreme-pressure/anti-wear performance and resistance to foaming, even when subjected to 10 percent 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 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 Synthetic Marine Gear Lube.

AMSOIL 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 a season prior to storage.
