The "90" rating reflects the oil's viscosity at high operating temperatures, ensuring it maintains a stable film thickness to prevent metal-to-metal contact. It ensures that the transmission system is ready to operate the moment the driver engages the gear, regardless of how cold the environment becomes.
Highway Driving Protection with 80W90 Synthetic Gear Oil
The "80W" component indicates its cold-temperature performance, where the "W" stands for winter. This stability prevents the lubricant from breaking down, which is a common issue with older, mineral-based gear oils during prolonged high-RPM operation.
As a result, the components remain clean and protected, even when the lubricant is subjected to sustained high temperatures over long distances. The synthetic base stock offers inherent resistance to thermal breakdown and oxidation, which translates directly into extended service intervals.
Highway Driving Protection With Enhanced Thermal Stability
Conventional oils can become thick and sluggish when temperatures drop, leading to difficult gear engagement and increased wear on startup. Furthermore, the oil's resistance to shear forces ensures that the viscosity remains consistent even under extreme pressure.
