A disposable oil drain pan and container combination features a large sidewall opening which is sealed by a removable screw cap. The oil pan and container combination is intended for use as (a) a container for new motor oil for purchase at a retail establishment, and (b) a disposable drain pan receptacle for use in changing oil in an automobile. The capacity of the container is preferably five quarts so that its contents can be emptied directly into the crankcase of an automobile during an oil change. After the contents have been emptied into the crankcase, the container assembly is set aside until time for the next oil change. At that time, the large screw cap is removed from the side for the container and the container is laid flat beneath the crankcase so that the used oil can drain directly into the container through sidewall opening. After the draining procedure has been completed, the cap is screwed on securely so that the filled container can be discarded.
