Abstract: A method and apparatus for changing engine motor oil more quickly and simply than previously existing methods. To change oil on a gasoline or diesel engine, the conventional oil filter is removed and an adapter is screwed in its place. An inlet oil port of the adapter connects with the oil filter inlet line and an outlet port of the adapter connects to the oil filter outlet line. The adapter top is sealed with a recessed O-ring extending around the periphery so that oil can be pumped through the adapter into and out of the engine without leaking. The adapter inlet and outlet ports are connected by hoses/tubes to an external container with its own internal piston. The engine is turned on to idle and the engine oil pump pumps used oil from the oil pan out through the adapter outlet port into the external container.
