Abstract
A lubricant composition comprises: a) a mineral base oil; b) a synthetic base oil; c) a dialkyl carbonate; d) conventional additives; and e) viscosity index and pour point improvers.
Component c) is the product of transesterification of a dialkyl carbonate with an alcoholic mixture consisting of at least 98% by weight of branched alcohols having the general formula (see formula I) where m is an integer and n is zero or a whole number, with the condition that the total number of carbon atoms in the molecule (I) is between 10 and 18.
