ABSTRACT:
A hybrid lubricant in which microfine PTFE particles are uniformly dispersed in an oil carrier that includes a small but effective amount of an oil-soluble organic molybdenum compound, the hybrid lubricant being diluted with a major amount of a conventional lubricating oil. In operation, a thin film of the molybdenum compound is developed on the rubbing metal surfaces of the lubricated engine, the film reacting in the high-temperature, high-pressure environment of the rubbing surfaces to form a fluoride to which the PTFE particles bond to impart thereto an extremely low coefficient of friction to afford the benefits of both solid and fluid lubrication. The hybrid lubricant minimizes friction under all operating conditions regardless of their severity, and it reduces wear on the engine.
