What is a Motor Oil?

Motor oil, engine oil, or engine lubricant is any of various substances comprising base oils enhanced with particularly anti-wear additive plus detergents, dispersants and, for multi-grade oils viscosity index improvers. Motor oil is used for lubrication of internal combustion engines. The main function of motor oil is to reduce friction and wear on moving parts and to clean the engine from sludge and varnish. It also neutralizes acids that originate from fuel and from oxidation of the lubricant, improves sealing of piston rings, and cools the engine by carrying heat away from moving parts.
