ABSTRACT:
An apparatus and method for removal of spent oil from an oil pan reservoir of an internal combustion engine includes a flexible tube engageable through the dipstick sleeve of the engine. In the preferred embodiment, a vacuum pump is used to draw vacuum within a receptacle to thereby draw spent oil from the oil pan reservoir of the engine through the tube for temporary storage and transportation in an environmentally safe manner. Valve cover opening fluid fill adaptors are provided for optionally introducing fluid, such as fresh motor oil, through the valve cover opening. A dipstick sleeve adaptor is also disclosed for introducing fluid, such as fresh motor oil, through the dipstick sleeve.
