Load Capacity and Wear Protection For vehicles subjected to towing or hauling operations, the EP (Extreme Pressure) additives in 75w-90 synthetic gear oil are indispensable. The "90" suffix denotes the viscosity measured at 100°C, which determines the oil's ability to maintain a robust film thickness under high-temperature, high-shear conditions.
Maintenance and Best Practices. Always consult the vehicle owner's manual to ensure compatibility, as some manufacturers require specific friction modifier packages for optimal performance in wet clutch applications.
