What are the three filters in car maintenance?
2 Answers
Car maintenance three filters refer to the oil filter, air filter, and fuel filter. The air filter's function is to filter the air before it enters the cylinder, removing impurities, dust, sand, and other foreign particles. The fuel filter's role is to filter out solid contaminants such as iron oxide and dust, as well as water, from the gasoline. The oil filter's purpose is to remove various impurities from the engine oil, ensuring the proper functioning of the lubrication system. The first car maintenance is usually required within 5,000 kilometers or three months, and most vehicles come with a free first maintenance service. During the first maintenance, the engine oil and filters should be replaced, fuel cleaning additives should be added, and the engine cooling system, coolant level, and electric system cooling system should be checked. Other components and fluids should also be inspected.
I drive frequently, so the 'three cleanings' maintenance is essential for my daily car care. It includes cleaning the air filter, replacing the oil filter, and the fuel filter. The air filter is responsible for filtering dust and debris from the intake air; the oil filter ensures the engine oil stays clean, reducing wear; while the fuel filter screens out impurities in the fuel to prevent clogs. After each maintenance session, the car feels more powerful, fuel-efficient, and gives me peace of mind. If neglected, a clogged air filter can reduce intake efficiency, causing the engine to lack oxygen and shudder; a failed oil filter allows contaminants into the engine, accelerating part wear and potentially leading to repair costs in the thousands; an aged fuel filter may also cause uneven fuel supply, increasing the risk of breakdown. I’ve learned to replace the air filter myself to save money, but for the others, it’s best to visit a professional shop—recommended every 5,000 km or six months—to avoid roadside issues. Paying attention to these small tasks helps the car last longer and reduces repair hassles, making it really practical.
