How Often Should Car Filters Be Replaced?
2 Answers
The replacement intervals for various car filters are as follows: 1. Oil filter: (1) When using lower-quality mineral oil, the oil filter should be replaced every 5,000 kilometers or 6 months. (2) When using average-quality full synthetic oil, the oil filter should be replaced every 5,000-7,500 kilometers or 10 months. (3) When using PAO oil with the strongest anti-degradation performance, the oil filter should be replaced every 10,000-15,000 kilometers or 12 months. 2. The replacement interval for the air filter is between 10,000-15,000 kilometers. 3. The replacement interval for the cabin air filter is also between 10,000-15,000 kilometers. 4. Since fuel filters are divided into external and internal filters, the replacement interval for an external fuel filter is approximately 20,000-40,000 kilometers, while the replacement interval for an internal fuel filter is between 40,000-80,000 kilometers.
As a car owner who drives frequently, I always remind my friends that the replacement time for the air filter in the car depends on the vehicle model and the recommendations in the owner's manual. Most cars require a change every 12 months or 10,000 to 15,000 miles. This is crucial because a clogged filter can allow dust into the engine, increase fuel consumption by 20%, and even damage engine components. My car is mainly used for commuting, so I check the filter every time I change the oil and replace it early if it's dirty. Driving in dusty rural areas with worse conditions might require replacement every six months. Neglecting it might save a little money in the short term, but engine repairs can be costly. I recommend having a technician assess the filter's condition during every maintenance check—don’t wait until engine problems arise. Safety comes first.
