Abstract

Abstract A self mixing funnel according to the teachings of the present invention is shown as including an outer funnel portion and an oil retainer. The oil retainer is suspended within the outer funnel portion with its filling open end below the filling open end of the funnel portion. Oil may then be placed in the oil retainer and gasoline can be poured into the oil retainer for mixing with the oil and overflowing the filling open end of the oil retainer into the outer funnel portion for discharge therethrough. In its most preferred form, the oil retainer further includes a discharge open end having a releasably sealing stopper. An elongated rod is further provided attached to the stopper and including a float and an enlarged member. The float floats on the mixed liquid in the collection container for removing the stopper from the discharge open end of the oil retainer when a predetermined level is reached. The enlarged member allows manual raising of the stopper from the discharge open end of the oil retainer and for visually indicating when the level in the collection container reaches the predetermined level.
