OIL, LUBRICANT COMPOSITION HAVING IMPROVED LUBRICITY AND INCREASED COEFFICIENT OF PERFORMANCE, USES AND MECHANICAL EQUIPMENT

摘要

The present invention discloses an oil comprising at least one alkyl aromatic compound wherein the oil viscosity is lower than 3.0 cSt at the temperature of 40 °C. The oil of the present invention shows a lower viscosity variation as a function of the temperature, what contributes to reduce the cooling system equipment wear and increase the equipment operation lifetime, for example, the operation lifetime of the cooling compressors. It also an object of the present invention a composition comprising said oil in combination with at least one fluid of the hydrocarbon (HC) type and its uses in mechanical equipments and mechanical equipments made with said oil and/or composition.
