Whether your car’s engine has a carburetor or is fuel injection, whether it’s powered by gasoline or diesel fuel, a clean air filter is a MUST. Many experts agree that changing your filters regularly may have more to do with prolonging the life of your vehicle than any other factor.
Have you noticed that your engine performance isn’t what it used to be – especially at high speeds? Check your air filter. It may be dirty and can reduce your gas mileage as well as increase emissions.
Your air filter extracts dirt and dust particles from the air and should be checked with every oil change. If you can’t see bright light, such as sunlight, through the filter at all points, it needs to be replaced.
If the filter is only slightly dirty, you can try cleaning it by tapping it – bottom side down – on a hard, flat surface. You should replace your air filter as needed. Air filters may need to be replaced more frequently if you live or drive on dirt roads or in dusty areas.
