Abstract
The instant invention provides a lubricant composition having improved four-ball antiwear properties. The lubricant composition includes a base oil and one or more alkylethercarboxylic acid corrosion inhibitor(s) having the formula: wherein R is a straight or branched chain C-Calkyl group and n is a number of from 0 to 5. The lubricant composition also includes an ashless antiwear additive including phosphorous. The four-ball antiwear properties are reported as an average diameter of wear scars pursuant to ASTM D4172. The average diameter of the wear scars resulting from the lubricant composition are at least 5% smaller than the average diameter of the wear scars resulting from a standard that includes the base oil and the antiwear additive and that is free of the one or more alkylethercarboxylic acid corrosion inhibitor(s).
