How Your Air Filter Can Improve Fuel Economy

Your car needs clean air. Replacing your air filter allows fresh air to pass through your engine to mix with fuel, improving fuel economy.

A Dirty Filter Inhibits Airflow

Air filters trap tiny particles and contaminants in paper or synthetic fibre media. The more the media fills with dirt and debris, the harder the engine must work – and the more your fuel consumption will rise. But when you replace your filter, cleaner air mixes with the fuel, generating a higher MPG.

Changing an air filter is an inexpensive, quick fix that can easily be achieved on the driveway. Aim to change yours approximately every 15,000 miles – more often if you drive in particularly dusty conditions –to keep your fuel economy at its best . Your owner’s manual will offer advice specific to your model on when to change your filter too.

Unfortunately, you can’t tell whether your filter is clogged just by looking at it because the filter clogs from the inside. However, if you hold it up and find that little light can pass through, there’s a good chance it’s clogged enough to warrant a replacement.

Quick tip: a dirty air filter should always be replaced, not cleaned.
