发明名称 Oil change method
摘要 An oil change aid device having a concave collection receptacle formed from a thin circular plastic sheet which is attached to and supported by a heavier plastic strip bent into a cylinder. A slot in the cylinder provides a hand hold to permit readily holding the device in one hand. This device is held in one hand and placed near a drain plug of an oil pan and the drain plug is then loosened through the plastic sheet using the other hand. The plastic sheet captures and contains the drain plug, and also protects the hands, arms and clothing from the drain oil. After the drain plug is removed the device is moved to permit the oil drain into a conventional oil pan and the oil poured from the device into the oil pan to permit retrieving the plug from the device.
