Lubricating composition

Abstract

In the field of lubricating compositions, notably lubricant compositions for automobile vehicles, in particular to the field of lubricant compositions for transmissions, for gear boxes or for bridges, there is disclosed a lubricating composition including at least 30% by weight of the composition of at least one monoester, at least one polyalphaolefin oil (PAO) for which the kinematic viscosity measured at 100° C. ranges from 40 to 3,000 mm2·s−1 and at least one polyalphaolefin oil (PAO) for which the kinematic viscosity measured at 100° C. ranges from 1.5 to 10 mm2·s−1. Also disclosed is the use of this lubricating composition for reducing the fuel consumption of a vehicle equipped with a transmission, notably with a bridge or a gear box, lubricated by this lubricating composition.
