ABSTRACT:
An oil filter (10) includes a colloidal suspension (12) of PTFE particles less than 2 microns in size retained by capillary forces within the intricacies of the filter media (26) until the filter (10) is installed and engine oil flows at first engine start up following installation. The PTFE colloidal suspension (12) is completely and immediately released into the engine lubricating system when oil flow is initiated. The PTFE colloidal suspension (12) is introduced into the oil filter (10) as one of the last manufacturing steps. Oil filter (10) is disposed vertically with its outlet port (14) at the top. A quantity of the PTFE colloidal suspension is introduced into the outlet port (14) to initially fill a portion of the volume defined by a centertube (18) and a retainer (16). The PTFE colloidal suspension passes through openings (20,24) into contact with filter media (26). The capillary forces acting between filter media (26) and the PTFE colloidal suspension (12) cause the colloidal suspension (12) to be drawn in and retained within the intricacies of the filter media (26) fibers.
