Filters: Your Vehicle’s First Line of Defense

Filters are your vehicle’s first line of defense to ensure performance, longevity and interior comfort, according to the Car Care Council.

The oil filter traps contaminants, allowing the oil to flow through the engine unrestricted. The fuel filter separates harmful contaminants that may cause problems with carburetors or intricate fuel injectors. The air filter traps dirt particles, which can cause damage to engine cylinders, walls, pistons and piston rings. The air filter also plays a role in keeping contaminants off the airflow sensor (in fuel-injected cars). The cabin filter helps trap pollen, bacteria, dust and exhaust gases that may find their way into a vehicle’s ventilation system.

“Your air filter has a big job since your car’s engine can use more than 10,000 gallons of air for every gallon or fuel burned,” said Rich White, executive director, Car Care Council. “Regularly checking all of your vehicle’s filters and replacing them as needed is a simple and inexpensive way to care for your car.”  

Filters are normal wear items that require regular checks and replacements. Factors that affect replacement intervals include mileage/time, driving habits, driving and road conditions, type of filter and vehicle type.
