Which outcome results when lubricating oil viscosity decreases in an idling engine?

💡 Explanation

Decreased viscosity allows thinner oil film, increasing contact stress and accelerated wear via adhesive wear mechanism. Therefore, engine component wear rate increases, rather than enhanced fuel combustion or stable oil bearings, because the hydrodynamic lubrication regime degrades.
