  • Patent number: 4533042
    Abstract: The present invention provides a motor oil change kit, especially for use by do-it-yourselfers, in which all that is needed for conveniently and cleanly changing the oil may be packaged together in a way that increases the chances that the motorist will not become intimidated by the project, but become habituated to this way of getting the oil changed, and that increases the chances that the motorist will unerringly bring the used oil to an authorized collection facility. Four types of kit are shown, each with its own advantages, but with many features in common. Each provides a closeable container of new oil, a collector for used oil, and a convenient system for either closing the container used for collecting the used oil, or for transferring the used oil from the collector to the emptied closeable container in which the new oil had been contained.
