Abstract
A drainable oil filter for an engine of a motor vehicle which comprises a cylindrical canister having a closed first end and a second end adapted to be screwed onto the engine of a motor vehicle. A mechanism on the closed first end of the cylindrical canister is for draining residual oil from the cylindrical canister. After oil in a crankcase of the engine of the motor vehicle is drained and before the second end of the cylindrical canister is unscrewed from the engine of the motor vehicle, the draining mechanism when operated by a person will allow the residual oil in the cylindrical canister to exit safely therefrom into a suitable container, without soiling the person positioned under the draining mechanism.
