Abstract: The present invention relates to oil collecting structure and more particularly to a cabinet or structure for the home garage into which drain oil and fresh oil dregs may be dumped and in which it may be collected for proper ecologically sound disposal. The structure consists of a cabinet divided into a sink portion and a drainboard portion. The drainboard portion is immediately adjacent the sink portion and portions of all or some of the structure are covered by sheet metal covers or inserts. The sink and its insert are shaped to slope downwardly from the outer margins or edges towards the center where a drain aperture is provided. The sink insert drain aperture fits telescopingly within the sink portion aperture and may be adapted so that containers for the oil may be connected to it. The shaping of the sink potion and sink create troughs from the exterior margins and corners to the center drain aperture.
