ABSTRACT:
A first pump can withdraw waste fluid from an oil pan reservoir and optionally, can be used to introduce flushing fluid through the oil filter and internal oil lubrication distribution passage system, to recirculate the flushing fluid within the internal oil lubrication distribution passage system, to withdraw the waste flushing fluid from the oil pan reservoir for disposal and storage in an external storage receptacle. An air purge connection is provided for evacuating fluid retained within the oil filter element and any fluid remaining in the internal oil lubrication distribution passage system into the oil pan reservoir prior to withdrawal of the fluid by the first pump. A second pump is provided for supplying fresh motor oil from an external storage receptacle through the oil filter and the internal oil lubrication distribution passage system. Optionally, a remote oil filter and drain mounting bracket provides a central, easily accessible location within the engine compartment for connection to the oil changing apparatus and for changing the oil filter element. A drain plug adapter is connectible to the oil pan reservoir to provide connection to the first pump. Methods for removing waste or spent fluid and introducing fresh fluid through the oil filter element and internal oil lubrication distribution passage system, and for introducing, recirculating and removing flushing fluid from the internal oil lubrication distribution passage system are also disclosed.
