Which outcome results when lubricating oil’s viscosity increases due to thermal degradation inside a constantly running gearbox experiencing high boundary shear?

💡 Explanation

Increased viscosity from oil degradation elevates the *viscous dissipation*, generating more frictional heat near gear teeth surfaces. Because the oil carries less heat, gear temperatures increase; this occurs rather than improving cavitation or wear, where cleanliness may play a larger part under normal conditions.
