The oil drain bolt is loosened by turning clockwise and tightened by turning counterclockwise. When loosening the oil drain bolt, as the bolt is about to detach from the oil pan, it is necessary to use a pre-prepared oil-catching device to collect the oil before removing the bolt. Below are some related details: 1. Engine oil: Engine oil, also known as engine lubricant, serves multiple functions such as lubrication, reducing friction, aiding in cooling, sealing against leaks, preventing rust and corrosion, and cushioning impacts. It is often referred to as the "blood" of a car. 2. Precautions: Never use an adjustable wrench to remove the oil pan bolt, as it can easily damage the bolt. Before draining the oil, slightly loosening the oil cap can help the old oil flow out more smoothly. When tightening the oil pan bolt, apply just enough force to secure it—avoid over-tightening to prevent stripping the threads. Some oil pan bolts come with copper washers to prevent leaks; these washers and the bolts themselves should be replaced periodically.
