TL;DRAbstract
The New York Central R.R. Technical Research Dept., finding the procedures currently employed by industry in evaluating the quality of diesel lubricating oils to be inadequate, has designed a test procedure which places particular emphasis on the oxidation stability of an oil. Tests previously employed by the railroad's laboratory were inadequate for separating the various oils into good and bad categories. Most oils submitted for laboratory approval passed, but later many caused serious engine distress in the field. In addition to this, the tests used were extremely time-consuming, sometimes running as long as several weeks. The laboratory's researchers, after months of work, were convinced that the resistance of an oil to oxidation was highly indicative of its general performance in a diesel engine; field correlation substantiated this theory to their complete satisfaction. The procedure was accelerated and a simple mathematical interpretation of results followed the construction of
