Filter Guide for Your Automobile

We discussed the fluids in your automobile in a previous blog post; now let’s discuss the filters. Whether you drive a car, truck, crossover, or SUV, you have filters that need to be changed on a regular basis. If these filters get clogged, your engine performance and fuel economy will suffer. In addition, clogged filters can damage the engine, and, in the case of the cabin air filter, a clogged filter can make you sick.

Air

All vehicles have an air filter in the engine. This filter is needed to remove the dirt and contaminants that are found in the outside air. Once the air is cleaned, it flows past the mass airflow sensor and into the combustion chamber. The air is burned with fuel to produce engine combustion. The air filter should be changed every 12,000 miles. Low-mileage drivers need to change it once a year.

Cabin

Check your owner’s manual to see if your vehicle has a cabin air filter. If it doesn’t, there is permanent netting that purifies the air that blows through the vents. If it does, this filter needs to be changed every 30,000 miles on average. It’s a good idea to check your vehicle manufacturer’s recommendations for changing this filter as the mileage durations vary.

Fuel

All vehicles also have a fuel filter. The fuel filter does for the fuel what the air filter does for the air. It purifies the fuel before it is sprayed into the combustion chamber by the fuel injectors. Even the most expensive fuel in town has sediment and contaminants in it. These things can clog the fuel filter if it is not changed every 30,000 miles. Low-mileage drivers should change it every two years.

Oil

You will find an oil filter in every automobile. This filter is changed during a lube, oil, and filter. Frequent oil changes ensure that your engine is protected and prolong its life. The general recommendation for oil changes is every 3,000 miles. If you put synthetic motor oil in your automobile, this duration is extended to every 5,000 or 7,500 miles on average.

Transmission

Finally, most vehicles have a transmission filter that is changed when the transmission fluid is changed. On average, a transmission fluid flush and refill should be done every 30,000 miles. If your vehicle has been acting up lately when it is shifting gears, you probably need to have your transmission fluid changed.
