A process for changing oil in an internal combustion engine equipped with the oil change device, capable of facilitating flushing and scrub cleaning of moveable parts in an internal combustion engine having an oil pan with a drain plug opening an internal lube oil distribution passage system, the oil change device including:
- an oil filter adapter adapted to be sealingly connected to an engine oil filter mounting boss located on the internal combustion engine, said adapter having at least two nozzles, a first nozzle in fluid communication with an engine oil pump located in the oil pan and a second nozzle in fluid communication with the internal lube oil distribution passage system of the engine;
- a remote oil filter mounting boss having first and second apertures and a mounting bracket attached thereto, said mounting bracket positioned on the engine remote from said engine oil filter mounting boss;
- an oil filter removably mounted on said remote oil filter mounting boss;
- a first inlet hose connected to said first nozzle and said first aperture of said mounting bracket;
- a second outlet hose connected to said second nozzle and said second aperture on said mounting bracket;
- a pump-out line connected to the drain plug opening having a coupling member at a remote end, said coupling member adapted to removably contact an external pump device;
- and
- a fill line connected to said second outlet hose said fill line having a coupling member attached at a remote end, said coupling member adapted to removably contact said external pump device;
- the process comprising the steps of:
- connecting said pump-out line and said fill line to said external pump device;
- removing spent oil from the oil pan by applying a suitable suction force through said pump-out line on said spent oil contained in the oil pan, said suction force exerted by said external pump device;
- after said spent oil is removed, introducing a measured amount fresh oil into the engine through the internal lube oil distribution passage system in fluid communication with said fill line, said fresh oil introduced under sufficient pressure to produce a spray pattern sufficient to permit contact between said fresh motor oil and the movable engine parts;
- and
- uncoupling said pump-out line and said fill line from said external pump device after said fresh oil is introduced.
