Oil enhancing multifunction filter

An improved oil filter cartridge, for an internal combustion engine, of a type having a container with an input port for connection to an output of an oil circulating system of the engine to receive unfiltered oil from said engine, and an output port for connection to an input of said oil circulating system of said engine to discharge filtered and reconditioned oil back into said oil circulating system, said container having filter means positioned between said input port and said output port for removing particulate contaminants above about 20 microns in circulating through said cartridge from said engine oil, said filter cartridge including an input side adjacent the input port and the filter means, wherein said improvement comprises:

• said input side of said cartridge being filled with a liquid lubricating vehicle having dispersed therein from about 1/2 ounce to about 1 ounce of agglomerated masses of particles of solid polytetrafluoroethylene, said particles having an average size of about 3 microns, said agglomerated masses ranging in size from about 60 to about 20 microns;
• said lubricating vehicle providing means for circulating said agglomerated masses of about 20 microns through said engine;
• whereby said agglomerated masses of about 20 microns are added to the oil circulating system as soon as the cartridge is connected into said oil circulating system, and, as the engine is operated, the agglomerated masses having a size above of about 20 microns gradually break apart to a size capable of passing through said filter means to provide constant addition of lubricating polytetrafluoroethylene particles to enhance lubrication of said engine by the oil circulating system during the life of said cartridge.
