Abstract: An apparatus for connection to the oil input of an engine which facilitates the emptying of oil contained within a can into the engine. The apparatus comprises a cutting element connected concentrically above the side wall of a base by means of a stand. During use, the operator positions the can above the cutting element and pushes downwardly causing the cutting element to puncture the bottom of the can thereby emptying the oil through the cutting element and through an aperture in the base into the engine. The cutting element includes a rounded step to facilitate removal of the can after emptying. An orientation device is provided to orient the base with respect to the oil input to facilitate easy access to the cutting element. In the preferred embodiment, the orientation device comprises a downwardly biased sprocketed flange which engages a protrusion extending upwardly from the bottom of the base.
