- lubricating compositions for improving the cleanliness of an engine. Improving the cleanliness of an engine generally involves reducing the formation of deposits, including the formation of high temperature deposits such as varnishes, lacquers or deposits of carbon or coke. Such deposits may be formed on the hot surfaces of the engine parts such as throat bottoms of the pistons or the axes of the turbos.
