Oil lubricants, commonly known as lubricating oils or simply lubricants, are used to reduce friction and wear in mechanical systems, protect against corrosion, dissipate heat, and seal out contaminants. They are widely employed in various industries and applications. 
Lubricating oils come in various grades and formulations, each designed to meet the specific requirements of the equipment and operating conditions. The choice of lubricant depends on factors like temperature, load, speed, and the type of machinery or application. Proper lubrication is essential to minimize wear, reduce energy consumption, and extend the life of equipment
