An oil change device to facilitate the collection of the spent motor oil from an internal combustion engine's ferromagnetic crankcase and ferromagnetic oil filter, having a flexible tube connecting a sealing cover unit to an oil collection container. Permanent magnets, imbedded in the sealing cover unit provide a means to attach the sealing cover unit to the crankcase and oil filter. The distal end of a wrench shaft protrudes through an orifice in the base member and extends to the superior surface of the baffle member. A wrench socket that fits the crankcase drain plug head is connected to the distal end of the wrench shaft and a socket wrench, attached to the proximal end of the wrench shaft, is used to unscrew and remove the crankcase drain plug. An oil filter piercing tool is connected to the distal end of the wrench shaft and used to pierce the skin of the oil filter when a striking blow is delivered to the proximal end of the wrench shaft. The spent oil from the crankcase and oil filter flows by gravity into the sealing cover unit, through the flexible tube, and into the oil collection container.
