Abstract
A molybdate ester represented by the following formula: where R1 is a hydrocarbon chain, R2 is either a hydrogen atom or a hydrocarbon chain, and m and n are independently from 1 to 5, is effective when used in a lubricating composition in an amount sufficient to provide about 50-5000 ppm of molybdenum, with respect to friction and wear reduction, while providing improved protection against copper and lead corrosion.
