Which outcome occurs when lubricant viscosity drops excessively in an automotive engine?

💡 Explanation

Increased friction and component wear result from reduced viscous lubrication because the mechanism, hydrodynamic lubrication, depends on viscosity maintaining a separating film. Therefore the rise in friction is the consequence, rather than reduced fuel consumption under normal operation.
