An elongated flexible oil spout has one end portion provided with internal threads for engagement with external threads of a plastic oil bottle. An intermediate portion of the oil spout is formed from accordion fold snap-lock segments which connect to a conical tip portion. A snap-on cap is provided at each end of the oil spout for preventing leakage. A butterfly valve adjacent the threaded end portion of the oil spout allows the flow to be regulated. An adaptor is provided with opposite end portions having different diameter external threads for engagement with internal threads of an oil drain aperture on an engine block and with the internal threads of the oil spout. A butterfly valve is disposed intermediate these threaded ends for controlling flow from the engine block. The adapter is utilized in conjunction with the flexible oil spout to allow oil to be drained without spillage from the engine block. The butterfly valve in the oil spout and in the adapter cooperates with valve seats which may be formed integrally with the oil spout or adapter, or may be formed from inserts. The valve seat and butterfly valve may have cooperating magnetic portions for maintaining the valve in a closed position.
