EVALUATION of ENGINE PRESERVATIVE OILS: PART ONE
Industrial Lubrication and Tribology
Article publication date: 1 June 1949
The use of “preservative” motor oils was a development of the recent war. The need for rust prevention has been recognised for many years, but only in the last decade were efforts concentrated to prevent rusting in an efficient and scientific way. Engine oil specifications have changed during the past ten years to comply with the higher requirements resulting from changes in engine design. The preservative type motor oils, which were developed during the same period, must meet these more rigid specifications and also act as corrosion preventives. Engine Preservative Oils serve the double function of preservation and lubrication. As a preservative, the oil should fully protect steel or any other metal which may be found in an engine assembly, whether the engine is stored or in operation. As a lubricant, it must comply with the exacting requirements set for automotive and aircraft engines. Because of the complexity of aircraft motors, specifications are generally more severe for aircraft than automotive engine preservatives. Illustrations of these specifications are presented for automotive oils, and only reference will be made to aircraft oils. Film forming engine preservatives, as required by the U.S. Bureau of Ships, will not be discussed because of lack of oily constituents.
