How often should the oil filter and air filter be replaced?

[VivianLynn]

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.

Buddy, don't underestimate these filters. I reckon the oil filter should be changed along with the engine oil, basically every six months or 8,000 kilometers. The air filter needs replacement less frequently, maybe once a year or every 20,000 kilometers. From a cost-saving perspective, timely replacement of these small parts is truly worthwhile: not changing the oil filter can clog engine lubrication and increase fuel consumption; a dirty air filter restricts airflow and reduces fuel efficiency. Last time, my car suffered because I delayed replacing the air filter—it struggled to breathe on the highway, costing me over a thousand bucks in repairs. The filters themselves cost just a few dozen yuan; replacing them early avoids major repair hassles and saves a significant amount in the long run. Especially for older cars, developing a habit of regular checks keeps the car in good shape and your mood at ease. Plus, there's plenty of maintenance knowledge available online—tutorials are everywhere.

From a safety perspective, I fully understand that not changing the oil filter on time can lead to oil contamination and accelerate engine damage; a clogged air filter affects air intake, causing higher fuel consumption and even stalling risks. My experience is: change the oil filter with the oil cycle, at least every 8,000 kilometers. The air filter should be checked and replaced within 15,000 kilometers. Driving safety depends on this, and regular maintenance ensures safe driving. The manual clearly states the standards to avoid small issues turning into major disasters. For example, last time I delayed changing the air filter, the car had difficulty starting and I had to call a tow truck. Taking timely action brings peace of mind.

As an environmentally conscious user, I believe changing filters is also beneficial for the planet. The oil filter is replaced every 5,000 kilometers or so to prevent dirt buildup; the air filter is renewed every 15,000 kilometers to enhance engine cleanliness, directly reducing exhaust emissions and carbon footprint. My routine is to inspect and replace the oil filter every six months, with a slightly longer interval for the air filter. Driving in the city exposes the car to more dust, prompting me to proactively shorten the replacement cycle, making the vehicle more efficient and less polluting. A small investment leads to significant environmental benefits—filters are inexpensive and easy to replace, and doing it yourself can contribute to greener travel. Reducing the frequency of car repairs also lessens resource consumption. Let's take action together to make the air a little cleaner.
