Yes, it must be changed. When performing car maintenance, it is necessary to replace the engine oil with qualified products and change the oil filter at the same time. This ensures better usage of the engine oil and effectively filters out impurities within the oil, preventing long-term clogging issues. Below is relevant information about oil filters: 1. Location: The oil filter is typically located in the engine's lubrication system, with its upper part connected to the oil pump and the lower part connected to various components within the engine that require lubrication. Generally, the oil filters used in car engines are non-cleanable disposable filters, so the oil filter needs to be replaced along with the engine oil during maintenance. The oil filter is also one of the car maintenance items, usually requiring replacement every 5,000 kilometers. 2. Function: The role of the oil filter in the engine is to filter out harmful substances from the engine oil, ensuring a good working environment for components such as the crankshaft connecting rod and turbocharger, and providing lubrication and cleaning functions.
