ABSTRACT:
An oil changing system that utilizes one oil pump for draining contaminated oil from a vehicle and pumping clean oil into the vehicle without contamination. The inventive device includes a tank, a pair of wheels attached to the tank, a motor connected to a pump, a pair of couplers attached to opposing sides of the pump, a first filter and a second filter, a volume indicia attached to the side of the tank, a cavity within the tank which contains a light, and a drain pan fluidly connectable to the pump by a drain hose. The user positions the drain pan below the oil drain spout of the engine to receive the contaminated oil. The contaminated oil that is received by the drain pan is then drawn by the pump through the drain hose where after the contaminated oil is dispersed through an exhaust hose. The exhaust hose may be connected to a pipe system within a building structure to drain the contaminated oil into a common reservoir.
