Las composiciones lubricantes son productos que, introducidos entre dos superficies móviles reducen la fricción entre ellas, facilitan el movimiento y reducen el desgaste. Una composición lubricante para motores se compone de una base, que puede ser mineral, semisintética o sintética, y un conjunto de aditivos que le confieren sus propiedades y determinan sus características. Lubricating compositions are products that, introduced between two moving surfaces reduce friction between them, facilitate movement and reduce wear. A lubricating composition for engines is composed of a base, which can be mineral, semi-synthetic or synthetic, and a set of additives that give it its properties and determine its characteristics.
Las principales funciones que cumple un lubricante en el motor son dispersar y transportar las partículas producto de la combustión y el desgaste al filtro, distribuir homogéneamente la temperatura desde la parte inferior del motor hasta la parte superior actuando como un refrigerante, evitar la corrosión, evitar la herrumbre por la acción del agua producto de la condensación y sellar actuando como una junta de determinados componentes. The main functions of a lubricant in the engine are to disperse and transport the particles of combustion and wear to the filter, homogeneously distribute the temperature from the bottom of the engine to the top acting as a coolant, prevent corrosion, avoid the rust by the action of the water product of the condensation and seal acting as a joint of certain components.

La base de un lubricante por sí sola no ofrece toda la protección que necesita un motor, por lo que es necesario adicionar varios aditivos. Los aditivos cumplen determinadas funciones y se pueden clasificar en: antioxidantes, antidesgaste, antiespumantes, antiherrumbre, detergentes, dispersantes, espesantes, antifricción y controladores de ácidos, o neutralizantes. Adicionalmente, una composición lubricante puede incluir mejoradores de índice de viscosidad para mantener la viscosidad frente cambios de temperatura. En el estado del arte se describen diversas composiciones lubricantes que comprenden una base, mejoradores de índice de viscosidad y aditivos. El documento US 6303548 divulga una composición lubricante de clasificación SAE 0W40.
