GTP HSYN7590P5R 75W-90 Synthetic Gear Oil (5-Gallon Pail)

GTP HSYN7590P5R 75W-90 Full Synthetic Gear Oil (5-Gallon Pail)

This 75W-90 full synthetic gear oil is a premium, high-performance lubricant engineered for heavy-duty truck axles, differentials, and manual transmissions operating under extreme temperature and load conditions. It provides exceptional film strength, superior thermal stability, and outstanding protection against wear, corrosion, and oxidation — ensuring reliable performance over extended drain intervals.

Key Features:

• Premium Synthetic Base Oils: Formulated with advanced synthetic base stocks for superior oxidation resistance, reduced friction, and extended component life.
• Outstanding Extreme Pressure (EP) Protection: Meets or exceeds API GL-5 and MIL-PRF-2105E performance levels, safeguarding hypoid gears and bearings under heavy torque and shock loads.
• Wide Temperature Range Performance: Maintains optimal viscosity and lubrication from sub-zero cold starts to high-temperature hauling conditions.
• Improved Fuel Efficiency: Low-friction formulation helps reduce parasitic losses and improve drivetrain efficiency.
• Excellent Seal Compatibility: Compatible with common elastomers used in heavy-duty driveline systems, reducing the risk of leaks and seal deterioration.
• Corrosion & Rust Protection: Advanced additive system protects against rust, pitting, and corrosion even in the presence of moisture.
• Extended Drain Intervals: Suitable for long-haul, severe-service, and extended drain applications as recommended by OEMs.
