Abstract : An analysis of the causes of the instability of the viscosity characteristics of oils is presented. Correlations are made between the structure of the molecules and the tendency of the oils to break down. It is demonstrated that the larger molecules present in oil can be torn apart by the violent motions which they experience in modern machinery. From fundamental considerations, predictions can be made on the stability of the large molecules which are used as oil additives, and of their breakdown by certain types of machinery. This knowledge should enable more intelligent choice to be made in compounding oils than before, and reduce dependence on trial and error. (Author)
