A clean air filter protects the engine from harmful waste without obstructing airflow. To promote engine health, most automotive manufacturers recommend replacing the air filter every 15000 to 30000 miles. But does replacing your car’s air filter also improve gas mileage?
Dirty air filters reduce airflow – Air filters trap contaminants in a media made of paper and synthetic fibers. Over time, this media becomes filled with dirt, preventing the engine from function properly. As a result, the engine will work harder and use more fuel.
This affect isn’t as noticeable on modern, fuel injected engines, Late-model vehicles use one or more sensors to measure the amount of air entering the engine. The vehicle’s on board computer uses this information to adjust engine operation as needed. To some extent, the computer can compensate for a dirty air filter. If however the air filter is clogged with dirt, the computer may not be able to.
Clear air filters improve performance and economy – Late model vehicles aren’t as sensitive to a dirty air filters as older vehicles are, but that doesn’t mean they don’t benefit from air filter replacement.
