Which outcome occurs in a lubrication system when oil viscosity significantly increases from expected values?

💡 Explanation

Increased oil viscosity leads to higher shear stresses and viscous drag within the lubricant film; the **viscous friction** converts input power into heat, because more energy is expended to overcome the increased resistance; therefore, power consumption goes up rather than decreased lubrication because film formability less dominates.
