Claim 10:
11. An oil drainage apparatus for use with an engine that includes an oil pan and an oil drainage port that is threaded, said oil drainage apparatus, comprising:
a base member including a housing having a top wall and a bottom wall opposite the top wall and a continuous sidewall extending between said top wall and said bottom wall so as to, together, define said interior area, said continuous sidewall having a front wall section defining said selector channel;
wherein said selector channel extends laterally and is in communication with said interior area and is bounded by a left locking slot and the right locking slot opposite said left slot;
a connection member extending upwardly from said base member and having a plurality of external threads complementary to the threaded oil drainage port of the engine;
an oil drainage body extending upwardly from said connection member and having a continuous sidewall defining a plurality of apertures in fluid communication with the oil pan of the engine;
wherein said connection member and said oil drainage body defining and sharing a common internal tubular space in fluid communication with said interior area of said base member;
a drain magnet slidably movable in said common internal tubular space between a closed configuration blocking said plurality of apertures and an open configuration displaced from the plurality of apertures;
wherein said drain magnet includes a drain magnet polarity;
a first actuation magnet movably mounted in said interior area of said base member having a first predetermined polarity that is opposite to said drain magnet polarity;
the second actuation magnet movably mounted in said interior area of said base member having a second predetermined polarity that is the same as said drain magnet polarity;
an actuation lever pivotally mounted to a rear wall section of said continuous sidewall of said housing of said base member, said actuation lever having an elongate and linear configuration that extends outwardly through said selector channel and that is coupled to said first and second actuation magnets, said actuation lever being selectively and slidably movable in said selector channel between a closed configuration situated in said left locking slot at which the first actuation magnet is vertically aligned with said drain magnet and an open configuration situated in said right locking slot at which the second actuation magnet is vertically aligned with the drain magnet.
