Motor oil, engine oil, or engine lubricant is any of various substances (comprising oil enhanced with additives, for example extreme pressure additives) are often used for lubrication of internal combustion engines. The main function of motor oil is to reduce wear on moving parts; it also cleans moving parts from the sludge, inhibits corrosion, improves sealing, and cools the engine by carrying heat away from moving parts.
Motor oils are derived from petroleum-based and non-petroleum-synthesized chemical compounds.

The base oils of some high-performance motor oils contain up to 20% by weight of esters.
