The Importance of Changing Your Filters

You need to be aware of the maintenance schedule for your vehicle — especially for filter changes. Many people do not think of changing the filters on their vehicles and often do not take the vehicle in for service at the appropriate times. Ignoring your vehicle’s filters is asking for trouble.

Air Filter

You should check the condition of your air filter every 3,000 miles or three months. If it is dirty — pull it out and check both sides — replace the filter. The air filter keeps dust and debris from entering the engine. When it gets too dirty, the engine cannot breathe properly, which could cause problems with running and could affect fuel mileage.

Fuel Filter

The fuel filter is not a filter you can easily check yourself. Some vehicles have two fuel filters — on under the car on near the frame and one in the engine compartment, usually near the firewall. Your owner’s manual will tell you when you should change the fuel filter. The fuel filter makes sure anything that gets into the gas tank doesn’t end up in the injectors. The fuel injectors have a very small nozzle that sprays fuel into the cylinders. If the nozzle gets clogged, the engine will not run properly or may not run at all.

Oil Filter

You should change the oil filter every time you change the oil. Most vehicles recommend changing the oil and oil filter every 3,000 miles or three months, whichever comes first. Some vehicle manufacturers have extended the time to change the oil, but it is still a good idea to change the oil at the 3,000-mile mark. Dirty oil could cause oil sludge to form in the oil galleys. When that happens, the oil cannot lubricate essential parts and your engine could freeze up.

Transmission Filter

This is another filter that you cannot easily change yourself. It is inside the transmission pan. Transmission service requirements vary widely from vehicle to vehicle. Check your owner’s manual for the transmission service timeframe. A clogged transmission filter could affect the way your vehicle shifts, which could also affect fuel mileage. If left dirty long enough, you could damage the transmission.

Cabin Air Filters

Cabin air filters are usually found behind the glove box if your vehicle has them. Your owner’s manual will tell you when you should change them. These help keep the air inside the vehicle clean.
