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 100° C. 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.

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 %.

Abstract: A lubricant composition containing an anti-deposition component having an anti-deposition effect which is especially useful for the lubrication of refrigeration compressors and in reducing or removal of unwanted deposits in constricted areas in a refrigeration system.

Abstract: This invention relates to lubricant compositions comprising a polyalkylene glycol and an ester wherein the polyalkylene glycol has the formula (I): RO—(CH2CH(CH3)O)n—CH3 where R is an alkyl group with 1 to 15 carbon atoms and n=1 to 35. The lubricant compositions of the invention do not readily form stable emulsions with water. This feature makes the lubricant compositions of the invention particularly suitable for use with air compressors where it is very difficult to exclude moisture.
