How Often Do I Need To Change My Car’s Air Filter?

It might seem hard to believe, but a part as simple as the air filter can do a lot of damage to your engine if you don’t change it regularly. TRUE Automotive can change all of your vehicle’s filters when they need it, but let’s talk about the air filter in this blog post. A clogged filter can affect engine performance, allow dirt and grime into the engine, and even make the inside of your car smell like gasoline.

What Does the Air Filter Do?

Your automobile needs air in the combustion chamber so it can start when you turn the key and keep running as you drive. The air flowing into the engine must be as pure as possible, however, to prevent foreign substances from clogging and damaging the engine. The air filter grabs debris, dirt, and other harmful contaminants and traps them to purify the air before the air flows into the engine.

How Often Should I Replace the Filter?

Your vehicle’s engine needs a new filter once a year or every 12,000 miles, whichever milestone you hit first. This removes the dirty filter before it gets too clogged and blocks airflow into the engine or releases excess dirt into the engine. A clean air filter restores airflow and is able to purify the incoming air better. This keeps your engine running efficiently and improves gas mileage, an added benefit.

How Can I Tell if My Air Filter Is Clogged?

A visual inspection is the best way to tell if your vehicle’s filter is clogged. It’s easy to check your air filter. Just use the diagram in your owner’s manual to find the air filter in your engine, remove the cover, pull the filter out, and take a good look at it. It should be white. If it is brown or gray, it’s caked with grime and it’s time to replace it. A clogged air filter can affect your vehicle’s performance, including

  • Decreasing the throttle response
  • Increasing the engine’s wear and tear
  • Lowering your vehicle’s fuel economy
  • Reducing the engine’s power
  • Stalling the engine or causing it to stutter

When your engine is starved of air, this causes the air/fuel mixture in the combustion chamber to be heavy in gasoline or “rich.” Too much fuel will not only cause engine performance issues and could even stall the engine because it’s flooded, but it will also make the engine burn away the excess fuel, which returns exhaust system issues including an emissions test failure.
