    Abstract: An engine lubricant, especially an SAE OW engine lubricant is described. The engine lubricant has at least 15 wt% of at least one diester and not more than 15 wt% of additives, wherein said at least one diester, or mixture of said diesters if more than one is present, has a kinematic viscosity at 100°C of not more than 3.3, a viscosity index of at least 130, a pour point of not more than -30°C and a Noack evaporation loss of not more than 15 wt%. The diester is preferably selected from the group consisting of: a) reaction products of at least one C 5 to C 12 , preferably C 6 to C 10 , aliphatic dicarboxylic acid or anhydride thereof with at least one primary or secondary C 7 to C 12 , preferably C 8 to C 10 aliphatic alcohol, wherein, if said at least one acid is branched, then at least one of said at least one alcohol is linear and, if said at least one acid is linear, then at least one of said at least one alcohol is branched; and b) reaction products of at least one C 5 to C 12 , preferably C 6 to C 10 , aliphatic monocarboxylic acid with at least one polyalkylene glycol wherein the alkyl group is selected from a C 2 to C 4 alkyl group and mixtures thereof, and wherein, if said at least one poly(alkylene glycol) contains at least one repeat unit that is branched methyl group, then at least one of said at least one acid is linear and, if said at least one poly(alkylene glycol) contains only linear repeat units, then at least one of said at least one acid is branched.

    Abstract: An engine lubricant, especially an SAE OW engine lubricant is described. The engine lubricant has at least 15 wt% of at least one monoester and not more than 15 wt% of additives, wherein said at least one monoester, or mixture of said monoesters if more than one is present, has a kinematic viscosity at 1000C of not more than 3.3, a viscosity index of at least 130 and a Noack evaporation loss of not more than 15 wt%. The monoester is preferably the reaction product of a monohydric alcohol and a monocarboxylic acid wherein said monohydric alcohol is at least one saturated branched-chain aliphatic monohydric alcohol having between 16 and 36, carbon atoms and wherein said monocarboxylic acid is at least one saturated straight-chain aliphatic monocarboxylic acid having between 5 and 10, preferably 5 and 7, carbon atoms. In preferred lubricants, the monoester, or mixtures of monoesters, have a pour point of not more than -30 °C and a non-polarity index of at least 80.
