Abstract

Diester lubricating composition The present invention relates to - one or more diesters, each of said diesters being · a diol selected from 1,2-propanediol, 1,2-decanediol and 1,3-diols having 3 to 10 carbon atoms, and · two same or different monocarboxylic acids having a straight-chain or branched-chain hydrocarbon chain having 4 to 10 carbon atoms a diester formed therebetween, and - at least one base oil different from the diester and / or at least one additive different from the diester, said additive being selected from friction modifier additives, antiwear additives, extreme pressure additives, detergents, antioxidants, viscosity index (VI) improvers, pour point depressants (PPD), dispersants, antifoaming agents, thickeners, corrosion inhibitors, copper passivators and mixtures thereof, at least one base oil and / or at least one additive and relates to a lubricating composition containing the same.
