An oil drain receptacle attachment, integrated system and method of use for providing a closed, clean catch system for the requisition of used motor oil for recycling. The oil drain attachment itself is positioned between a flexible drain tube and a collection receptacle where the reversibly attachable oil drain attachment allows for securing of the flexible tubing to an opening of the receptacle, in operation, that is capable of initiating and ceasing flow, through an ‘on’ and ‘off’ functionality, in addition to intermediate, partial opening and closing positions, as well as providing ventilation that facilitates the exit of air with the introduction of used oil into a collection receptacle for transportation and disposal.
