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.
80w 90 Gear Oil Drain and Replace Tips
This low-temperature rating ensures the oil remains fluid enough to flow and provide lubrication during cold starts, preventing dry friction. Performance Under Load and Pressure What sets 80w 90 apart from standard motor oils is its ability to withstand extreme pressure.
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. The number 80w refers to the oil's cold-temperature viscosity, where the 'w' denotes winter performance.
