Summary:

THE chemical problems of engine lubrication associated with wear, detergency, and oxidation stability are discussed by the authors.A detailed examination is made of the stability of lubricating oils in engines. It was found that the oil rapidly becomes contaminated with solid oil-in-soluble materials that greatly affect its stability toward oxidation: In some cases, the stability after 1000 miles of use may be 1% of that of the fresh oil.By the addition of pure compounds to the oil, and also by the separation of the components of the oil-insoluble materials, it was determined that the metal salts, particularly the halogen salts, are the effective catalytic materials. Two possible methods for combating these catalysts are mentioned by the authors.A few experiments are also reported indicating a possible usefulness of these engine catalysts in laboratory oxidation tests
