How Often Should the Air Filter and Oil Filter Be Replaced?
3 Answers
The vehicle's cabin air filter should be replaced approximately every six months, though this interval can be adjusted based on actual usage conditions. The engine oil filter must be replaced together with the engine oil, typically when the vehicle has been driven for six months or 6,000 kilometers, or one year or 10,000 kilometers. Below is relevant information about air filters and oil filters: 1. Air Filter: The vehicle's air filter is a device that removes particulate impurities from the air and requires regular inspection and replacement. 2. Oil Filter: The vehicle's oil filter, also known as the oil element, is replaced simultaneously with the engine oil. Oil filters used in vehicles can be categorized into full-flow and bypass types. The full-flow filter is connected in series between the vehicle's oil pump and the main oil line, while the bypass type is connected in parallel with the main oil passage, filtering only a portion of the lubricating oil delivered by the oil pump.
When it comes to the replacement intervals for car air filters and oil filters, as someone who has been driving for twenty years, I believe this habit is quite important. For air filters, if you mainly drive in the city, I recommend replacing them once a year, or checking them every 10,000 to 15,000 kilometers. If you frequently drive on dusty rural roads, it's best to inspect them every 3,000 to 5,000 kilometers to prevent the filter from clogging and allowing dust to damage the engine. As for oil filters, they should generally be replaced every time you change the oil. The oil change interval depends on your car and the type of oil used—conventional mineral oil should be changed every 5,000 kilometers, while full synthetic oil can last 8,000 to 10,000 kilometers. Failing to replace them on time can lead to increased engine wear, slower acceleration, and higher fuel consumption. I always take care of these during regular maintenance. Trying to save a little money now might cost you a fortune in major repairs later.
There's no one-size-fits-all replacement schedule for air filters and oil filters—it depends on how you use your car. For example, a friend of mine driving in sandy areas might need to check the air filter every two to three months, and it's best to replace it every six months to avoid reduced airflow or even odors in the cabin. Oil filters are typically linked to oil change intervals, with baseline values provided in the vehicle manual—most cars recommend replacing both the oil and filter every 5,000 to 7,000 kilometers. Why so frequently? A clogged filter can let contaminants into the engine, causing rough operation. I've seen owners wait until warning lights appear, only to face doubled costs and engine damage. Regular checks are the simplest solution—spending a small amount ensures peace of mind and safety.
