Filters are a vehicle's first line of defense to ensure performance, longevity and interior comfort, according to the Car Care Council, and one message you can deliver to your customers.
There are certain points you and service advisors can explain to customers, such as that 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. Also explain how 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.
"An air filter has a big job since your car's engine can use more than 10,000 gallons of air for every gallon of fuel burned," says Rich White, executive director, Car Care Council. "Regularly checking all of a vehicle's filters and replacing them as needed is a simple and inexpensive way to care for a 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, and should be explained to customers.
