Which mechanism causes increased drag when lubricating oil degrades inside an engine?

💡 Explanation

Increased lubricant degradation means oil viscosity decreases; this increases fluid boundary layer thickness because viscous damping is reduced. Therefore, drag at components increases rather than decreases unlike with alternative optimal fluid film thickness designs.
