ABSTRACT:
A replacement filter for conventional throw-away spin-on oil filter cartridge on an internal combustion engine. The replacement filter uses a porous metallic filter element, preferably a woven stainless steel, pleated filter element, within a housing physically simulating the conventional throw-away spin-on oil filter cartridge. The housing is disassembleable, typically by unscrewing the top cap of the housing, for removal, cleaning and reuse of the filter element. This avoids the problems of cost and availability of replacement filters and of disposal of used filters. Various embodiments are disclosed.
