This invention is an enhanced oil filter which prevents unfiltered oil penetrating to the drivetrain when the bypass-valve opens up due to pressure between the entrance and the exit. This filter contains a case (30) which has an opening on top, a top-plate (31) that is connected to the opening case area composed of an entrance and an exit to which the oil flows in and out. Also contains a filter-box (40) located within the case (30) which filters out foreign substances, and a bypass-valve (50) located in the filter-box (40) which bypasses the oil to the exit when there is an abnormal oil pressure between the filter box (40) and case(30), when part of filter box is clogged due to foreign substances. A valve-filter (60) filters out oil that streams in through the above mentioned bypass-hole(44a) and the first spring (70) presses the valve-filter (60) close to the filter-box (40), and the filter-box (40) close to the top plate (31). Unlike the traditional oil filter; which fails to prevent the bypassing oil that does not filter to re-supply the engine's drivetrain, this filter does exactly that, thus reducing damage to the engine's drive train.
