How Often Should Car Air Filters Be Changed?

It's not always easy to know when to change your air filter. And when you think it's time to change your filter, do you know if it's time to change your engine air filter or your air conditioning filter? If you're wondering when to change your engine air filter, check out the signs below.

Decreased gas mileage

One of the most common problems you'll encounter when it's time to replace your car air filter is reduced gas mileage. Engines need good airflow to work properly. When the air filter gets dirty, it's harder for air to get in and the engine has to work harder. Your gas mileage won't be too bad at first, but after a while, you'll notice the numbers drop quickly. If you have recently noticed that you have to fill up your gas tank more often than usual, it may be time to check your air filter.

Ignition Problems

When your engine air filter becomes dirty, air can't get past the filter to the engine, which affects the car's entire emission control system. In turn, this clogs the spark plugs and prevents them from firing properly. As a result, you may experience ignition problems. When you try to start your car, does it turn over slowly or not at all? Consider checking the filter to see if this is the problem.

Replacement time

Check your owner's manual; it should tell you when the auto air filter should be replaced. This is usually every 12,000 to 15,000 miles, depending on your vehicle. If you have driven the air filter more than this number of times since you last changed it, it may be time to change it.

Remember, if you drive in sandy or dusty areas, your filter may need to be changed more often than the recommended time range for your vehicle. If your owner's manual says it's time to change your filter, it's best to pay attention to changing it rather than wait until you start noticing other problems.

Visual Inspection

A new air filter is usually white or off-white. You can visually inspect your engine air filter to see if it looks dirty or if it is full of debris. Keep in mind that sometimes air filters can become clogged with particles that are too small to see. However, if you notice that the filter is gray or full of particles, it's definitely time to replace it. The location of the air filter varies from vehicle to vehicle, so check your owner's manual to find out exactly where the filter is located.

Changing the auto air filter is usually not an expensive repair. It's a basic maintenance you need to perform regularly to keep your car running well. Be sure to keep an eye on your air filter, replace it when you start to notice signs that it's clogged, and keep your car in good condition for as long as possible.
