Every car has four main filters: the cabin filter, oil filter, fuel filter and air filter. The function of all these filters is to enable flows and catch impurities: the dust and contaminants in the air, the impurities in the fuel or the dirt in the motor oil.
Both gas and diesel vehicles use fuel filters, but it’s worth noting that some newer cars don’t actually use fuel filters. Some newer vehicles rely on a strainer that’s attached to the fuel pump. These are only meant to be replaced if the pump goes bad. So if you can’t find yours – don’t panic!
