Abstract

An oil filter assembly for an internal combustion engine includes a filter element disposed in a spin-on canister which is detachably secure to a mounting adaptor having a conduit normally permitting some of the filtered lubricating oil to bypass the main lubricating circuit of the engine. The filter element carries a plug which seals the bypass conduit when the canister is installed on the adaptor so as to disable the internal bypass circuit of the adaptor and force all of the filtered oil to flow to the main lubricating circuit.
