Since the engine oil is oxidized after a certain period of use and contains various foreign substances generated during the operation of the engine and the function of the engine oil is deteriorated, the conventional oil is discharged from the engine And new engine oil is injected into the engine.

[0003] Conventionally, engine oil has been replaced by opening an oil coke of an engine to discharge the waste oil in the oil passage of the engine to the oil drain by gravity and then injecting new oil into the oil cap of the engine. At this time, an engine oil injection device for injecting new oil into the engine may be used. Here, the oil drain and the engine oil injection device may be referred to as an engine oil change device.

However, in such a conventional engine oil changing apparatus and an engine oil changing method using the same, some of the waste oil can not be discharged from the engine due to gravity, and remains in the oil passage of the engine, thereby contaminating the new oil. This shortens the service life of the engine, shortens the engine oil change cycle, increases the cost of replacing the engine oil, and increases the amount of waste oil that is discarded, thereby accelerating environmental pollution.
