How Often Should I Change My Car's Air Filter?

One vehicle component that is often overlooked is the engine air filter. A clean air filter equates to a clean engine. This filter helps the engine run smoothly and seamlessly by blocking out external impurities like dust and debris. Whenever this filter gets clogged, you may experience various issues with your vehicle and its performance.

Signs That You Need to Change Your Car Air Filter

  • Filter appears dirty
  • Check engine light comes on
  • Decrease in engine power
  • Lowered fuel economy
  • Exhaust smoke 
  • Unusual engine sounds

Clean air plays a crucial role in the combustion process. If contaminants get into the engine chamber, it can cause significant damage to your engine parts. You may also struggle to accelerate your vehicle. To avoid having your engine working overtime, please remember to periodically change the air filter.

How Often Should I Check and Change the Air Filter?

On average, you should check the air filter on your car at least once a year. Depending on your car manufacturer, the interval for the filter change may vary. However, most mechanics notice that an air filter can last anywhere between 15,000 to 30,000 miles. How frequently you should replace your engine air filter can depend on how much driving you do.

Nevertheless, you should still check up on it once a year. If the filter looks dirty or off-colored, it is best to go ahead and change it. A brand new air filter is the wise choice to guarantee your engine will run its best and stay in tip-top shape.
