It must be recognized that the only real measure of quality in a lubricating oil is its actual performance in the diesel engine. This is apparent because of the impossibility of establishing limits on all physical and chemical properties of oils which can affect their performance in the engine over a broad range of environmental influences. Oil quality is the responsibility of the oil supplier, a term applicable to refiners, blenders, and rebranders of engine lubricants. As there are a substantial number of commercial lubricants marketed today, engine manufacturers and consumers cannot completely evaluate the entire spectrum of products available. As a result, the selection of a suitable heavy duty lubricant must be made in consultation with a reliable oil supplier capable of making product recommendations commensurate with the engine builders specifications and specific environmental influences as well as furnishing such a product on a consistent quality level.
