A method for lubricating engine parts, in which kerosene is added to engine lubricating oil. Upon running the engine, the kerosene is circulated through the engine, acting as a solvent to remove any deposits within the engine and cause the deposits to be expelled through the exhaust system.
Claims2
A method of improving the efficiency of an automobile having an engine which has a lubricant in the oil reservoir of the engine, comprising the steps of:
- providing an oil composition consisting essentially of 8%-20% by volume of kerosene and 80%-92% by volume of motor oil;
- determining the content of exhaust emissions of said engine and comparing said content to a hydrocarbon emissions content standard;
- draining the lubricant from the oil reservoir if said content exceeds said automobile emissions standard and adding said oil composition as the lubricant to the oil reservoir;
- circulating said oil composition through said engine by operating said engine;
- and
- retaining said oil composition as the lubricant within the oil reservoir when operating said engine during the normal operation of the automobile.
