COGENT GUARD HD SAE 85W-90 Heavy Duty Gear Oil API GL-5
COGENT GUARD HD 85W-90 GL-5 SERIES
Product Description:
COGENT GUARD HD 85W-90 GL-5 SERIES is a high-performance heavy duty gear oil engineered to provide superior protection for demanding drivetrain components. Formulated from premium quality base oils and an advanced additive system, this 85W-90 gear oil is specifically designed for use in automotive heavy-duty transmissions, axles, and final drives.
As an extreme pressure gear oil, this lubricant is specialized for heavy-duty axles and final drives where extreme pressures and sudden shock loadings are frequently encountered. This robust differential gear oil ensures a resilient lubricant film under diverse load conditions, making it an ideal axle gear oil for both on-highway and off-highway applications. Whether used as a manual transmission oil or a specialized truck differential oil, COGENT GUARD HD provides the thermal stability and anti-wear protection necessary to maintain equipment efficiency and longevity in high-torque environments
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.
