ABSTRACT:
An oil filter draining apparatus includes a bifurcated funnel with a first region defining an open top end and a second region defining a tapered spout. The apparatus further includes a plurality of channels formed within the support wall and extending downwardly to the spout and a rigid puncturing implement removably attached to the funnel and centrally aligned within the top end. Such a puncturing implement is anchored to the support wall and extends vertically up from the support wall and terminates at an axially opposed position from the spout. The puncturing implement is penetrable into one end of the existing filters and thereby causes oil to drain out therefrom while the existing filter is attached to the existing engine such that residual oil trapped within the existing filter is substantially drained before the existing filter is removed from the engine.
