Abstract: A system to change the oil from above the hood includes a reversible motor connected to the oil system, preferably the sump drain. The pump is further connected to a container. The pump initially draws the oil from the oil sump and directs it into an empty container. A full container of oil is then connected to the pump, which is then reversed, pumping the oil new oil into the engine's oil sump. Alternately, the system can be directed to and from the existing oil filter connection.

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.
