ABSTRACT:
A method is described to determine the valve train wear performance of a lubricating oil by adding to the lubricating oil from about 2% to about 9% by weight, based on the total weight of the lubricating oil, of a mixture of at least three carbon black components of mixed particle size and measuring the wear induced in a wear test.
