An automotive lubricating oil filter device comprising a main container body having inlets and outlets for the lubricating oil to be filtered, and a cylindrical filtering element through which the oil is filtered from the outer portion of the body inwardly to a central cylindrical core. The core contains a magnetized metallic helical structure within which is enclosed one or more longitudinal bars of magnesium metal. The magnetized helical spring serves to remove fine metallic particles from the lubricating oil, preventing agglomeration on the filtering element, in addition to preventing engine wear, and the magnesium metal serves to neutralize sulfuric acid generated in the engine. The structure with the helical spring and bars contained therein may be removed and cleaned to be regenerated without requiring disposal of the main filter structure and vice versa.
