What is the shelf life of an oil filter?

[Tricia]

Oil filters have a shelf life, typically ranging from one to two years. Below is an introduction to the shelf life of oil filters: 1. Unopened engine oil generally has a shelf life of 4-5 years. The contamination and deterioration of stored oil are primarily caused by exposure to moisture, oxygen, and impurities in the air. Therefore, opened engine oil must be stored in a sealed container. After maintenance at a 4S shop or repair shop, the oil bottle cap should be tightened immediately. It is important to note that since the original tin foil seal has been damaged, the remaining cap gasket provides limited isolation. At this point, a clean plastic film can be used to cover the bottle opening. To prevent damage, it is best to fold the film several times before placing it over the opening, then screw the cap back on for better sealing. 2. Oil filters have a shelf life, typically ranging from one to two years. Since oil filters are consumable parts and are replaced frequently, their shelf life is often overlooked. However, under normal circumstances, they do not expire.
