Abstract: An oil filter suitably formed to provide integrally therewith a turning attachment to facilitate the interchanging of oil filters on engines and the like which include an oil filter canister. In the preferred form the filter body has substantially cylindrical configuration, upon which an interlocking instrument is disposed on an outer surface thereof. Various forms of the invention provide an interengaging implement to coact with the interlocking instrument selectively so that the oil filter canister can be rotated in either direction along its longitudinal axis by means of lever bars which in one form are affixed to the interengaging implement and pivoted thereto so that when not in use, the lever bars can be folded to reside substantially parallel to the outer annular walls of the canister.
