An oil filter assembly and a method for testing the quality of engine oil is provided to improve measurement reliability by measuring capacitance related to dielectric constant of the engine oil at a place in which alien substances contained in the engine oil flow. An oil filter assembly(100) for testing the quality of engine oil comprises an inner body(110) having a cylindrical shape, a filter member(130), an outer body(140) space apart from the inner body, a first electrode plate(120), a second electrode plate(150), a lower cover(160) and a control unit(170). The inner body includes a filter accommodation part(113). The filter member closely adheres to the filter accommodation part and discharges alien substances of the engine oil introduced through an oil inlet(111). The outer body has and an oil passage(141) and an oil outlet(143). The first electrode plate is installed on the oil passage. The second electrode plate is installed at an inner circumference of the outer body. The lower cover has a first surface communicating with the oil passage and an upper surface on which a damping member(163) is formed. The controller is electrically connected the first electrode plate and the second electrode plate.
