This oil contains extreme pressure (EP) additives that activate under heat and load, creating a sacrificial layer on the metal surfaces. Always consult your vehicle's owner manual to confirm compatibility before draining the old fluid.
80W 90 Gear Oil for Manual Transmission: Performance and Protection
The number 90 signifies the high-temperature viscosity, indicating the oil's thickness and ability to maintain a protective film under operating heat and load. Conversely, in cold environments, it must not thicken to the point of failing to lubricate critical components during startup.
The balanced viscosity profile allows for smooth shifting in manual gearboxes while providing the necessary cushion for the hardened surfaces found in differential gears. Gear teeth do not slide against each other; they essentially roll and grind, creating immense contact stress.
