ABSTRACT:
Apparatus and method for removing dirty residual oil remaining in an automobile engine after its crankcase has been drained by conventional procedures. The apparatus of the invention comprises an adapter including a gasket for shunting oil away from a first conduit; a duct for delivering residual oil away from the conduit and into a receptacle below the engine; and an opening threaded to mate with an oil filter support post. After draining crankcase oil, the oil filter is removed and the ignition coil is disconnected to prevent ignition. The adapter is then attached to the oil filter support post, and the crankcase is filled with clean oil. The engine is cranked to operate its oil pump, and dirty residual oil held in the first conduit is expelled through the adapter and collected until clean oil appears.
