AMSOIL Universal Synthetic Marine Gear Lube 75w-80w90

Extreme Pressure Universal Gear Oil for Multiple Marine Applications — Outboard Lower Unit, Stern Drive, V Drive, Bow and Tunnel Thruster and Marine Transmission

 

API GL-4 and GL-5 Oil

AMSOIL 75w90, 80w90 Synthetic Marine Gear Oil GL-4, GL-5AMSOIL Universal Synthetic 75w-80w90 Marine Gear Lube is a high performance extreme pressure gear oil engineered to meet the demands of marine applications. Excellent ATV gear oil.

AMSOIL Universal Synthetic Marine Gear Lube is not affected by water. Industry standard testing demonstrates that AMSOIL Marine EP Gear Oil provides 50% more extreme pressure protection than the competition for long gear and bearing life. Testing also demonstrates zero foam in both new and water-contaminated samples of AMSOIL Universal Synthetic Marine Gear Lube; other conventional gear lubes can foam when mixed with water. The presence of foam in a lubricant disrupts oil film and promotes wear. See the results of the Extreme Pressure and Foam Stability Tests.

AMSOIL Universal Synthetic Marine Gear Lube meets the specifications of marine engine manufacturers and provides:

  • Excellent gear and bearing protection, even when contaminated with 10% water
  • Reduced friction and wear
  • Protection against shock loading caused by propeller cavitation
  • Outstanding marine corrosion and rust protection
  • Long seal life
  • Superior foam prevention
  • Performs in all outboard lower units, stern drives, V drives, bow and tunnel thrusters and marine transmissions that require either 75w90 or 80w90 and meet API GL-4 or GL-5 oil specifications

EP Gear Oil Protects Against Shock Loading Caused by Propeller Cavitation

AMSOIL Universal Synthetic 75w-80w90 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 an EP (extreme pressure) gear oil that provides superior protection from shock loading caused by propeller cavitation. Cavitation is common in high horsepower, high torque applications and occurs when the propeller spins too quickly, mixing air with water and losing traction, causing vibration, noise and lower unit shock loading. AMSOIL Universal Synthetic Marine Gear Lube offers superior protection for fast accelerating, high torque-horsepower engines.

Prevents Marine Corrosion and Rust

AMSOIL Universal Synthetic 75w-80w90 Marine Gear Lube is marine formulated, so it protects against corrosion and rust and is compatible with aluminum, copper and brass alloys.

Water Resistant

AMSOIL Universal Synthetic Marine Gear Lube is water resistant. It maintains extreme pressure protection even when contaminated with as much as 10% water. Water contamination increases the likelihood of foaming. The presence of foam in a lubricant disrupts oil film and promotes wear. AMSOIL Universal Synthetic Marine Gear Lube promotes longer seal life, preventing excessive water leakage.

FALEX and Foam Stability Test Results

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 test demonstrates that AMSOIL Universal Synthetic Marine Gear Lube is not affected by water and provides 50% more extreme pressure protection than its competitors for long gear and bearing life.
  • The Foam Stability Test demonstrates that conventional mineral gear oils can foam when mixed with water, yet AMSOIL Universal Synthetic Marine Gear Lube aced the test with absolutely no foam!

*The FALEX Test is measurement of a gear lubricant's extreme pressure and anti-wear properties. A high value in the FALEX Extreme Pressure Test relates to extra extreme pressure protection.

Multiple Applications

AMSOIL Universal Marine Gear Lube is SAE 75w-80w90 and replaces both 75w90 and 80w90 gear oils.

Oil Change Interval

Follow manufacturers recommended oil change intervals. It is generally a good idea to change gear oil at the end of the season prior to storage.

National Trade Publication Praises AMSOIL!Lubes-n-Greases
LNG Publishing Co. Inc.

In the March 2003 issue of Lubes 'n' Greases, Automotive Editor David McFall wrote an in-depth article on the subject of extended oil change intervals. He praised AMSOIL for their commitment to excellence and labeled AMSOIL "unshackled" for never conforming to industry norms and standards.

See why McFall
applauds AMSOIL as
a safe, cost-effective
and environmentally preferred oil change.

AMSOIL 10w30 Motor Oil and ten competing oils were subjected to a series of motor oil tests. These tests were performed in accordance with American Society of Testing and Materials (ASTM) test procedures. No oil outperformed AMSOIL in any of the tests! A comparison also reveals that AMSOIL costs less to use than all the competing motor oils!
