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. This oil contains extreme pressure (EP) additives that activate under heat and load, creating a sacrificial layer on the metal surfaces.
Understanding the 80w 90 Gear Oil Temperature Range
In hotter climates or during strenuous towing sessions, the oil must maintain its consistency to avoid becoming too thin. Decoding the 80w 90 Designation The naming convention of gear oils can often seem cryptic to the uninitiated, but it directly correlates to performance characteristics.
While 80w 90 is durable, it is not impervious to contamination. Over time, metal shavings from normal wear, dust, and moisture can degrade the oil's effectiveness.
Understanding the 80W 90 Gear Oil Temperature Range
The following table provides a quick comparison of 80w 90 against other common gear oil viscosities to help determine the best fit for your specific climate and driving habits. The number 80w refers to the oil's cold-temperature viscosity, where the 'w' denotes winter performance.
