Abstract
This paper discusses a laboratory evaluation of both ashless and ash-containing motor oils for use in modern internal combustion engines. The conclusion based on data from recognized laboratory engine tests is that ash-containing additives at the present state-of-the-art provide greater flexibility for overall quality in formulating motor oils. In addition, certain ash-containing materials offer a superior balance of overall crankcase lubricant performance.
