A hybrid oil filter assembly includes a housing and a first (e.g., conventional) oil filter element disposed in proximity to a bottom portion of the housing. The first oil filter element contains an open inner volume. A second oil filter element having a generally circular cylindrical shape is disposed circumferentially about a length of the first oil filter element. The second oil filter element may be made of rolled paper and filters particles of a smaller size than the first oil filter element (e.g., down to about one microns, thereby providing micro-filtering of the engine oil). |
