A lubricant is a substance (often a liquid) introduced between two moving surfaces to reduce the friction between them, improving efficiency and reducing wear. They may also have the function of dissolving or transporting foreign particles and of distributing heat. Engine Oil is a semi-synthetic high performance lubricant. It is designed for ultimate protection and performance on all naturally aspirated, fuel injected, turbo-charged and multi-valve cars fuelled by gasoline, diesel or LPG. Multipurpose Gear Oils are used for the lubrication of gears operated under severe conditions, including automotive applications. High quality HVI base stocks blended with a sulfur-phosphorous extreme pressure additive package provide superior performance including anti-weld, anti-scuff, and anti-wear properties. The function of grease is to remain in contact with and lubricate moving surfaces without leaking out under gravity or centrifugal action, or be squeezed out under pressure. At the same time, grease must be able to flow into the bearing through grease guns and from spot to spot in the lubricated machinery as needed, but must not add significantly to the power required to operate the machine, particularly at startup. The lubricating oil and grease market in India is of the order of 1.3 mn tonnes and is growing at around 4.5% annually. The moderate growth is paradoxically due to the supply of better quality of lubricants which have longer servicing capability. The lubricant market is estimated to grow to the level of 1.42 mn tonnes in 2006-07 and to approximately 2.00 mn tonnes in 2014-15. The Indian lubricants industry claims to be the sixth largest in the world. It has the presence of almost all major MNCs which include Shell, Mobil, Gulf Oil, Caltex. Some of these oil majors have even tied up or renewed old ties with public sector undertakings, thereby gaining the advantage of distribution and infrastructural networks. The industry is being constrained by high petroleum prices. The lube market consists of two major segments, automotive and industrial, having a market share of 60% and 40%, respectively. Most of the competition is crowding into the first category. In the automotive segment, while cars and two/three wheelers segment accounts for 30% of the market, diesel operated engines, trucks and other heavy vehicles have the bulk share of 70%.
