Abstract: An oil filter includes a housing, a first cylindrical metallic sieve received in the housing, a filter medium disposed between the first cylindrical metallic sieve and the housing, and an end cap. The end cap has a central outlet through which filtered oil exits and a plurality of peripheral inlets through which oil to be filtered enters. A spaced is defined by the first cylindrical metallic sieve, in which a support is securely mounted to a lower portion thereof adjacent to the central outlet. A filter element is securely retained in the space by the support for removing ferric particulate contained in oil to be filtered. The oil filter includes a second cylindrical metallic sieve held by two caps, a plurality of magnets, and a plurality of third metallic sieves being alternatively disposed around the second cylindrical metallic sieve and being held between the two caps.
