发明名称 APPARATUS AND METHOD FOR CHANGING OIL IN AN INTERNAL COMBUSTION ENGINE WITH OPTIONAL FLUSHING
摘要 <p>A first pump (30) can withdraw waste fluid from an oil pan reservoir and optionally, can be used to introduce flushing fluid through the oil filter (16) 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 (26). A second pump (32) is provided for supplying fresh motor oil from an external storage receptacle (22) through the oil filter and the internal oil lubrication distribution passage system. Optionally, a remote oil filter and drain mounting bracket (16) 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 (18) is connectible to the oil pan reservoir to provide connection to the first pump (30).</p>
