SUMMARY
Motor oil is classified as a mixture rather than a pure substance. It consists of base oils, which can be petroleum-based hydrocarbons or polyalphaolefins (PAO), combined with various additives such as antiwear agents, detergents, and viscosity index improvers. The composition of motor oil varies, often containing up to 20% by weight of esters to enhance the solubility of additives. This complexity in formulation confirms that motor oil is not a single compound, but a blend of multiple substances.
