Which outcome reduces efficiency when lubricating oil warms?

💡 Explanation

Decreasing oil viscosity with rising temperature causes increased flow, reducing generated hydrodynamic lift because viscous drag decreases, impacting load support causing breakdown rather than improving lubrication. Oil polymerization would increase viscosity under adverse chemical conditons.
