Car engines need an equal amount of fuel and clean air in order to run effectively and smoothly. Air filters are installed to make sure that your engine receives only cleanest air and prevent damage from small dirt.
Here are at least 4 benefits of changing your air filter regularly:
This is one of the biggest reasons to change your air filter regularly. The research indicates that replacing a dirty air filter increases fuel mileage on older, carbureted cars by as much as 14 percent if the filter is so dirty it affects driveability. Other studies claim a 10 percent raise in gas mileage and up to 15¢ per gallon fuel savings.
Clogged air filters can decrease air flow to the engine, and as a result, affect the emission control systems of the car causing an incorrect air-fuel mixture. It can also increase engine deposits caused by having too rich of a fuel mixture. Increased air flow to the engine allows it to operate properly reducing fuel consumption and reducing emissions.
Changing the air filter regularly helps lengthen engine life because the air filter is designed to trap damaging dirt and debris that can damage internal engine parts such as the cylinders and pistons. Engine damage can happen from particles as small as a grain of salt and result in costly repairs.
Air filters should be changed approximately every 12,000 to 15,000 miles, more often in dusty driving conditions. The owner’s yearly maintenance schedule will indicate how often the air filter should be replaced. A dirty air filter might appear clean but should still be replaced at the recommended intervals.
