Let’s Talk About Your Automobile’s Filters and When to Change Them

No Comments

One question we get a lot here at AutoFix is what filters does my car have? Your automobile has either three or four primary filters, each serving a different purpose. When they should be changed depends on the filter type and how much driving you do. Here is a list of the common filters found in automobiles and when you need to change them. Please note that the changing schedules are general recommendations. For milestones specific to your automobile, please check your owner’s manual to see what your vehicle’s manufacturer recommends.

1. Air Filter in the Interior Cabin

Most automobiles today have an air filter to purify the air that blows into the vehicle’s cabin through the vents. This is called the cabin air filter, and it needs to be changed approximately every 30,000 miles. This ensures the air that you breathe inside your car, truck, CUV, van, or SUV is always fresh and free of harmful things such as allergens, dirt, and engine exhaust.

2. Air Filter in the Engine

You’re likely more familiar with the engine air filter. This filter does for the engine what the cabin air filter does for the cabin. It purifies the air that is drawn into the engine to ensure that dirt and debris do not make their way into the engine’s combustion chamber. This is crucial in the performance of your automobile, so the filter needs to be changed every 12,000 miles.

3. Fuel Filter in the Fuel System

Your fuel filter is a unique filter that removes contaminants from the diesel fuel or gasoline twice. Fuel is filtered before it is drawn through the fuel pump, and then it is filtered once again afterward. This is because you cannot afford to have contaminants make their way into your automobile’s engine. If they do, you run the risk of damaging the engine beyond repair.

4. Oil Filter in the Engine

Finally, your oil filter should be replaced at every oil change. This is part of the service, so you needn’t worry about reminding the technician to change the oil filter. Instead of filtering the oil before it goes through your engine, the oil filter removes dirt and debris afterward. This keeps the oil clean so it is pure the next time it goes through the engine.

We don’t want you to have to worry about your car’s filters here at AutoFix in Franklin, TN. We will inspect and change them for you when they need it.
