February 10th, 2023 by

As a car owner, you want to be able to recognize and quickly address any potential issues with your vehicle. One of your vehicle’s most important yet often overlooked components is its air filter, which helps keep dust and dirt out of the engine. Unfortunately, a dirty or clogged air filter can cause major damage to your vehicle if left unchecked. Therefore, it’s incredibly important to know what signs to look out for so you can replace it when needed.

Our expert team at Meadowland of Carmel provides more insight on identifying signs quickly so you can have a worry-free, joyful driving experience. Learn more about recognizing common signs which could point towards needing a new filter for your ride.

What Happens if an Air Filter Is Dirty?

When air filters become blocked or clogged, it prevents the engine from receiving adequate air. This can lead to increased unburned fuel and emissions, resulting in decreased air quality. Accumulated soot builds up on the air filter, causing an even greater restriction on the air intake. As a result, your engine’s performance suffers and may even end up damaged.

How Can You Tell if Your Air Filter Is Dirty?

Keeping your car air filter clean ensures smooth running and efficient working of your car. Thankfully, you can determine whether your air filter needs to be replaced by looking for several signs below.

Reduced Gas Mileage

When the air filters become clogged, they reduce the amount of oxygen flowing into the engine, which reduces efficiency and causes your vehicle to use more fuel than usual. If you notice that your gas mileage has decreased significantly, this could indicate that your air filter is dirty.

Strange Engine Noises

As dirt accumulates in the air filter, it can create a vacuum inside the engine, causing it to make strange noises as it works harder than usual to draw in enough oxygen for combustion. If you hear anything out of the ordinary from under the hood, it’s best to get it checked out by a professional mechanic right away.

Decreased PerformanceDirty Air Filters

If you’ve noticed that your car isn’t performing as well as usual, your air filter might be dirty. With enough fresh air entering the engine, performance will improve significantly. This is because combustion requires oxygen. If there isn’t enough oxygen in the engine, combustion won’t happen efficiently, and power will be lost due to incomplete fuel burning.

Check Engine Light Comes On

One of the most obvious signs that your air filter needs replacing is when the check engine light comes on. This indicates something is wrong with your car’s engine and needs addressing as soon as possible. If the light stays on after you have checked all other possible causes, it could indicate that your air filter is clogged or dirty.

Black Smoke or Flames in the Exhaust

A surefire sign that your air filter needs replacing is if you start seeing black smoke or flames coming out of the exhaust pipe. This happens when fuel cannot properly mix with oxygen due to a blocked air filter, leading to combustion problems within the engine. If you notice this happening, get your air filter replaced as soon as possible.

The Smell of Petrol in the Exhaust

If you start smelling petrol from your car’s exhaust pipe, this could also indicate a blocked or dirty air filter. When an air filter becomes clogged or dirty, it restricts airflow into the engine, which makes it difficult for fuel and oxygen to mix correctly. As a result, unburned petrol will escape through the exhaust pipe, producing a strong smell of petrol fumes.

Your Engine Misses or Misfires

Another way to tell if your car’s air filter needs replacing is if your engine starts missing or misfiring while driving at high speeds or under load conditions such as accelerating quickly. The cause is likely to be restricted airflow due to a clogged or dirty air filter, which prevents fuel and oxygen from mixing correctly, resulting in poor performance from the engine.

If your car’s air filter is dirty, it can lead to a loss of acceleration. The engine needs a certain amount of air to function properly. When the air filter is dirty, it restricts the amount of air that can flow into the engine, which can cause a decrease in power.

Loss of Acceleration

If your car’s air filter is dirty, it can lead to a loss of acceleration. The engine needs a certain amount of air to function properly. A dirty air filter restricts the amount of air that can enter the engine, resulting in slower acceleration.

Can I Drive Without an Air Filter?

It’s possible to drive without a car air filter, but it’s not recommended. You also want to avoid dirt and debris clogging up other key components in your engine. Without the air filter, your engine won’t have the same level of protection from contamination, leading to poor performance and a greater risk of damage to your vehicle.

Even though driving without an air filter may be possible, it could cost you more in the long run with decreased performance and additional repairs down the road. Therefore, we suggest you always install a quality air filter in your vehicle.

How Often Does the Engine Air Filter Need Replacing?

Changing the engine air filter is one of your car’s most important maintenance tasks. This simple task can help to keep your engine running smoothly and efficiently. But how often should you change your engine air filter?

The answer to this question can vary depending on several factors, including the vehicle you drive and the air filter you use. However, typically, you need to change your engine air filter from every 15,000 to 30,000 miles.

Therefore, the next time you’re due for a service, ask your mechanic to check your engine air filter and change it if necessary. An engine air filter change can significantly affect your vehicle’s performance.
