Abstract: Oxidative degradation may be reduced in a lubricant composition which contains an oil of lubricating viscosity and at least about 1 percent by weight of a C1-C3 alkyl ester of a carboxylic acid of about 12 to about 24 carbon atoms, by including within the lubricant composition a sulfonate detergent in an amount sufficient to provide at least about 0.2 percent by weight sulfonate soap to the lubricant composition, wherein the weight ratio of sulfonate soap to phenate soap in the lubricant composition is at least about 0.35:1.
