When Each of Your Automotive Filters Need to Be Replaced

When do my auto filters need to be replaced? We get that question a lot here at Advanced Automotive. It’s important to always make certain that you have clean filters in your car, crossover, SUV, truck, or van. These filters help with your engine and fuel efficiency as well as protect your engine. One filter, the cabin air filter, also protects you and your passengers. It’s not expensive to get your filters replaced. This is a common factory-scheduled service. Let’s talk more about when these filters need to be replaced.

Oil Filter

The oil filter is one filter that you don’t need to think about because it is replaced every time you get your car’s oil changed. This filter works backward, if you will. Most filters work before, but the oil filter works after, i.e., motor oil is filtered after it has circulated through your engine rather than before to clean it of the debris it picked up during its circulation. This ensures the oil is clean once it goes through the engine again.

Air Filter

The air filter is different from the cabin air filter. The air filter cleans the air that goes into the engine. Air flows in through your grill to keep the engine cool and to supply the combustion chamber with the air it needs to produce detonation. The air that cools off your engine doesn’t have to be clean, but the air in the combustion chamber does. The air filter ensures that the purest air possible flows into the combustion chamber. This filter should be changed every 12,000 miles.

Cabin Air Filter

You noticed that we said in the introduction that the cabin air filter protects you and your passengers. If you’re the type of person who always has the fan, air conditioner, or heater running in your automobile, you may have wondered how the air is always so fresh. The cabin filter is the filter that keeps the air flowing into your vehicle’s cabin clean. It clears out dirt, debris, exhaust, and other contaminants. It needs to be changed every 30,000 miles.

Fuel Filter

Finally, the fuel filter is the only filter that cleans something twice. Gasoline or diesel fuel flows through the filter two times before it is sprayed into the combustion chamber by the fuel injectors. This is to make certain that the gasoline or diesel fuel is pure. As you can imagine, although it is refined, gasoline and diesel fuel can be dirty. They contain contaminants and sediment. A clean fuel filter removes this debris. Change the fuel filter every two years or 30,000 miles.
