Abstract: An apparatus for recycling liquids, such as, for example, used motor oil. For example, an outer container, such as a five gallon plastic container, is provided which contains unused oil. A pump can be used to pump out the unused oil for use. This leaves a liquid void in the container. A collapsible bag is contained within the container and has an external opening. Used oil may then be poured into the collapsible bag replacing the liquid void left when the unused oil was pumped out, but not contaminating the unused oil. When all of the unused oil has been pumped out, the contained with the bag of used oil can be recycled. Alternatively, other liquids can be recycled. Also, the collapsible bag can contain the unused oil.
