The Vital Role Clean Air Filters Play in Maintaining Vehicle Fuel Efficiency

Last updated 5 years ago

A quality air filter can go a long way toward improving your vehicle’s performance and fuel efficiency, which is why regular auto maintenance checks are so important. Read on to learn more about the important role that clean air plays in your vehicle and to determine if your vehicle could use a fresh, clear filter.

  • Precise Performance – Your engine uses fuel, air, and metallic pistons to power the rest of your vehicle. When your car draws power from the engine, a specific mixture of fuel and air is released into the space above your pistons. This mixture ignites, pushes the pistons, and causes your car to move forward. Unfortunately, even a small change in this ration can drastically reduce the fuel economy of your vehicle as irregular piston action will force your engine to compensate by using extra gas. Thankfully, your vehicle’s air filter maintains the ratio of gas and air by keeping airborne impurities out of your engine. Only a clean filter can guarantee this efficiency.
  • Clean Engine – Dirty air filters can also cause fuel deposits to form inside your engine. Fuel deposits occur when extra gas finds itself behind the pistons and is not properly ignited. This extra fuel will collect inside the engine and transform into a solid sludge. Eventually, these deposits will cause your engine to run hot and overheat. The extra strain on engine components will eventually cut down on efficient performance and ruin your gas mileage. Again, these problems could be prevented with a clean air filter. Make sure your engine is protected from preventative wear by checking your air filter today.
