1. Lubricating oils are commonly used as a lubricant for machines and engines to reduce friction and wear between mechanical components, improving their reliability and lifespan.
2. Lubricating oils can also be used as a hydraulic fluid for hydraulic systems, transferring power by using force of fluids. It is used in hydraulic machinery, such as excavators or cranes, to power the hydraulic cylinders and provide smooth operation.
3. Lubricating oils are used as a coolant for machinery and engines, absorbing and dissipating heat generated during operation. This helps to prevent overheating and damage to the mechanical components.
