COGENT GUARD HD SAE 80W140 Synthetic Blend Heavy Duty Gear Oil API GL-5

COGENT GUARD HD 80W140 GL-5 SERIES

Product Description:

COGENT GUARD HD 80W140 GL-5 SERIES is a premium, high-performance heavy duty gear oil developed from a high-quality synthetic blend of base oils and a highly advanced additive framework. Engineered to meet the demanding requirements of modern drivetrains, this high performance gear oil provides exceptional lubrication for automotive heavy-duty transmissions, drive axles, and final drives.

Formulated as an ultra-stable extreme pressure gear oil, this product is specialized for heavy-duty rear axles and final drives exposed to extreme operational pressures, high torque, and sudden shock loadings. The resilient formulation acts as a high-film-strength differential gear oil and axle gear oil, ensuring that highly stressed contact surfaces within heavy machinery and transport configurations are protected from severe mechanical wear. This commercial vehicle gear oil delivers stable, clean operation, making it a dependable selection for logistics networks, long-haul transport fleets, and severe-duty off-highway industrial gear assemblies.

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

Application :

• Suitable for use in all passenger cars, on-highway light and heavy-duty trucks, and commercial vehicles demanding an extreme-pressure 80W140 gear oil.

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

• Recommended for off-highway industries operating under demanding conditions, including construction, mining, quarrying, and agriculture.

• Highly applicable for other heavy-duty industrial and automotive gear oil setups involving hypoid gears operating under extreme conditions where high-speed/shock load, high-speed/low-torque, and/or low-speed/high-torque forces are present.
