Do Cars Have Three Filters?

Yes, every automobile has an air filter, a fuel filter, and an oil filter. Techway Automotive advises that your vehicle may also have a transmission filter and a cabin air filter. You can check your owner’s manual to see the filters that are found in your automobile. The owner’s manual will also give you the mileage duration at which each filter needs to be changed. Let’s talk about the general recommendations below.


The air filter needs to be changed every 12,000 miles. It’s important to change it annually if you haven’t driven 12,000 miles within a year. The air filter keeps the air burned in the combustion chamber clean. You cannot afford to have contaminants or dirt deposited in the combustion chamber. The filter purifies the air to avoid this from happening.


If your car, truck, or utility vehicle is equipped with a cabin filter, check the owner’s manual to see the recommended changing schedule. Cabin air filters need to be changed anywhere from 6,000 miles to 30,000 miles. It depends on the filter type. Either way, you want to have a clean cabin filter in your vehicle at all times to keep the air inside the passenger cabin clean.


The fuel filter needs to be changed every 30,000 miles. You can change it every two years if you don’t do a lot of driving. As with the need for clean air in the combustion chamber, there is also a need for clean fuel in the combustion chamber. As such, the fuel flows through the fuel filter twice. This ensures there are no contaminants or sediment left in the fuel once it is burned.


It’s easy to remember when the oil filter needs to be changed because it is changed when the oil is changed. Generally, this means your vehicle gets a clean oil filter every 3,000 miles. If you put synthetic motor oil or a synthetic blend in the engine, the oil filter will be changed every 5,000 to 10,000 miles. A clean oil filter is crucial to your engine’s protection.


Finally, your automobile may have a filter in the transmission to keep the transmission fluid clean. The general recommendation for replacing the transmission fluid is every 30,000 miles. As with an oil filter, the transmission filter is changed at this time.
