Is motor oil the best thing on earth? Motor oil is a type of lubricant used in internal combustion engines. It reduces friction between moving parts, helps to cool the engine, and protects it from wear and tear. Motor oil is made from a base oil, which is typically a petroleum-based product, and a variety of additives.
Motor oil is essential for the proper functioning of an internal combustion engine. Without motor oil, the engine would quickly overheat and seize up. Motor oil also helps to reduce emissions by preventing the escape of harmful gases from the engine.
