What are the three filters in maintenance?
2 Answers
In car maintenance, the three filters that need to be replaced refer to the air filter, oil filter, and fuel filter. Below are the detailed introductions: 1. Air filter: Its function is to filter the air before it enters the cylinder, removing impurities, dust, sand, and other foreign objects. Typically, the cleaning interval for an air filter is 6,000~8,000 km. However, sometimes even if the replacement time or mileage has not been reached, the inner side of the filter element may be covered with dust or oil, requiring immediate replacement. Air filters are divided into dry and wet types, with most cars using dry air filters. 2. Oil filter: It removes various impurities from the oil, ensuring the normal operation of the lubrication system. The oil filter can be replaced along with the oil during an oil change. If the oil filter is clogged, it can be replaced, or the dirty filter element can be cleaned, dried, and reused. 3. Fuel filter: It is recommended to drain the water and sediment from the fuel filter weekly, with a general cleaning and replacement interval of 2,000-3,000 km.
I've had a deep understanding of maintaining the three filters after driving for so many years. They are the air filter, oil filter, and fuel filter. The air filter is responsible for filtering dust from the air drawn into the engine, preventing engine wear; the oil filter purifies impurities in the engine oil, protecting internal components and extending their lifespan; the fuel filter removes debris or moisture from the fuel, avoiding clogging in the fuel system. During regular maintenance, if these three are not replaced in time, the car is prone to increased fuel consumption, weakened power, or even engine failure, leading to higher repair costs. I personally check them every 5,000 kilometers. The air filter is simpler and can be replaced by myself to save money; the others are best handled by professional shops. Developing this habit not only keeps the car running smoothly but also ensures its overall health, especially in dusty urban areas. Regular maintenance is essential.
