ABSTRACT:
A filter for the engine oil systems of internal combustion engines, fits into a standard oil filter cartridge or recepticle. The filter cartidge may be of any conventional type, but should be of the best quality, and able to remove as much as possible of the particulate contaminents to provide the best possible mechanical filtering function. The body of this filter cartridge is impregnated with specific chemicals of the type normally added to the lubricating oils by the manufacturer before distribution to counteract the inevitable oxidation, nitration and changes in acidity that degrade a lubricating oil in normal use. The chemicals must be impregnated into the filter in such a manner as to leach into the crankcase oil, over a period of time, in amounts that will compensate for losses in the system, and the amounts and types of chemicals can be structured for any given car, for a given mileage, and for given driving conditions. Timely changes of this filter can prolong the life of the lubricating oil, and the engine.
