How is Lubricating Oil produced from base oil?

Lubricating oil is any oil used in or to aid lubrication such as Engine Oil and Grease.

Lubricating oil is produced by “Blenders and Compounders” who combine base oil with 1% to 20% application-specific chemical additives, which enhance the performance of the base oil. The “compounded” Lubricating oil (which could be, motor oil, gear oil, grease etc.) is then packaged and sold to end users.

Therefore most lubricants you use in your day to day activities or in factories are manufactured by adding some specific chemical additives to base oil to form that specific Lubricant.
