COGENT GUARD HD SAE 80W-90 Heavy Duty Gear Oil API GL-5

SAE 80W-90 Heavy Duty Gear

Product Description:

COGENT GUARD HD 80W-90 GL-5 SERIES is a high-performance heavy duty gear oil range formulated from premium base oils combined with an advanced technological additive system. This robust automotive gear oil is specifically developed to provide exceptional service across automotive heavy-duty drivetrain components, focusing on demanding manual transmissions, drive axles, and final drives.

Formulated as an advanced extreme pressure gear oil, it delivers enhanced structural protection, superior film strength, and shear stability under intense operational pressures, heavy shock loads, and high-vibration environments. The balanced composition acts as an optimized differential gear oil and axle gear oil, ensuring that critical contact points within highly stressed gear sets remain insulated from premature surface fatigue, micro-pitting, and wear. It serves as a dependable commercial vehicle gear oil choice for maintaining total drivetrain protection and clean mechanical operation across flexible transit, logistics, and severe off-highway heavy machinery setups.

Features & Benefits:

• Exceptional thermal & oxidation stability protects against deposit formation and oil thickening, thus maintains the life and performance of lubricant and transmission.

• Outstanding anti-wear properties and excellent film strength provides exceptional equipment protection, that not only results in fewer breakdowns but also helps improve transmission efficiency.

• Excellent rust and corrosion protection for longer component life.

• Compatibility with seals and gaskets, leads to minimize oil leakage and reduced contamination

Applications:

• Suitable for use in all passenger cars, on-highway light and heavy-duty trucks, and flexible transport configurations demanding high-quality 80W-90 gear oil protection.

• Ideal for heavy-duty manual transmissions, drive axles, and final drives requiring strict API GL-5 gear oil level performance.

• Highly applicable for rugged off-highway industries including construction, mining, quarrying, and agricultural machinery operations.

• Recommended for other heavy-duty industrial and automotive applications involving hypoid gears working under conditions where high-speed/shock load, high-speed/low-torque, and/or low-speed/high-torque settings exist.
