How often should the oil filter and air filter be replaced?
2 Answers
Replace the oil filter every 5,000 kilometers or every six months, and the air filter every 15,000 kilometers or about once a year. The oil filter, also known as the oil grid, comes in full-flow and bypass types. It is used to remove impurities such as dust, metal particles, carbon deposits, and soot particles from the engine oil to protect the engine. The air filter refers to a device that removes particulate impurities from the air. It consists of two parts: the filter element and the housing, and comes in three types: inertial, filtration, and oil bath. Its main requirements are high filtration efficiency, low flow resistance, and the ability to be used continuously for a long time without maintenance.
As a frequent driver, I always prioritize the replacement of the oil filter and air filter. The oil filter usually needs to be changed along with the engine oil, every 5,000 to 10,000 kilometers or every 6 months, as this prevents dust from entering the engine and avoids wear. The air filter has a longer interval, typically every 15,000 to 20,000 kilometers or once a year, but the environment plays a crucial role: if driving in dusty areas, I shorten the interval. My habit is to check them during every maintenance service. Filters are cheap, costing just a few dozen yuan, but neglecting them can lead to engine problems that cost thousands to repair. Regular replacement not only keeps the car running smoothly but also improves fuel efficiency and extends engine life. Remember, the owner’s manual is the most reliable guide—don’t just rely on others' advice. Changing them yourself is also simple, with basic tools easily getting the job done.
