Abstract :- Lubricants are available in our daily lives for functioning as coolants, to dissipate heat and lubricate different surfaces which can be either in solid, liquid or gaseous forms. It reduces friction by the formation of thin film between two surfaces in contact and by improving efficiency and reducing wear. For any system to work efficiently and effectively appropriate lubricant is needed. Fresh lubricating oil needs to meet specifications of Original Equipment Manufacturers (OEMs). Applying lubricant regularly on tool increases life on usage and durability but a situation comes when the oil starts degrading may be due to depletion of additives or tool break down. Degraded oil is tested by using different physicochemical properties and also by employing different sophisticated analytical techniques like infrared spectroscopy (FTIR), Gas chromatography (GC), Inductively coupled plasma atomic emission spectroscopy (ICPAES), etc. In this article, we shall discuss some basics of lubrication, different lubrication regimes and various kinds of lubricants used for various industrial and automotive applications. Some case studies of oil and also their representative formulations, testing and interpretation of results is being presented for understanding of various lubricants.
