Abstract:
1. An oil filter draining apparatus for discharging oil contained within an existing filter before the existing filter is removed from an existing engine, said oil filter draining apparatus comprising: a funnel having an open top end and a tapered spout terminating at a bottom most edge of said funnel, said funnel having a support wall formed substantially medially of said funnel and at a top entrance of said spout such that said top end and said spout are in fluid communication; a plurality of channels formed within said support wall and extending downwardly to said spout; and a puncturing implement removably attached to said funnel and centrally aligned within said top end, said puncturing implement being anchored to said support wall and extending vertically up from said support wall and terminating at an axially opposed position from said spout; wherein said puncturing implement is penetrable into one end of the existing filter 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; wherein said puncturing implement comprises an elongated and rectilinear shaft having a first threaded outer section terminating above said support wall, said shaft further having a second threaded outer section juxtaposed subjacent to said first threaded outer section and being removably inserted into said support wall, said shaft being provided with a pair of rectilinear grooves traveling along a major longitudinal length of said first threaded outer section, said grooves being diametrically offset along opposed sides of said first threaded outer section such that residual oil contained within the existing oil filter is guided downwardly along separate paths and into said spout.
