What are the precautions for replacing the oil filter?

Precautions for replacing the oil filter include: 1. The engine oil and oil filter should be replaced simultaneously to help extend the engine's service life; 2. When removing the oil filter, use a filter wrench or appropriate tools to prevent damage to the threads at the connection point. After prolonged use, the filtration efficiency of the oil filter will decrease, and the oil pressure passing through the filter will drop. The oil filter is designed to remove impurities, gums, and moisture from the oil, delivering clean oil to various lubrication points. To reduce friction resistance between moving parts in the engine and minimize component wear, oil is continuously delivered to the friction surfaces of moving parts, forming a lubricating oil film for lubrication.
I've been pondering over changing the oil filter for more than a decade. You must wait until the engine cools down completely before starting - getting burned is no joke. The filter must be purchased according to the exact vehicle model. Last time I bought a cheap mismatched one, and the oil leakage drove me crazy. The tools needed are just a filter wrench, oil drain pan, and gloves - gloves are mandatory as engine oil makes hands terribly dirty and hard to clean. Before removing the old filter, first loosen the drain plug and wait until all the black oil flows out completely. When installing the new filter, apply a layer of fresh oil on the rubber gasket, hand-tighten it first, then give it just half a turn with the wrench. After finishing, start the car and observe for ten minutes - only no leakage means success. Never pour waste oil down the drain - the most eco-friendly way is to bottle it and send it to an auto shop for recycling.
