Gas, electricity, diesel, or imagination—no matter what powers it, your car has filters, and those filters need to be changed from time to time. Otherwise, your vehicle will not perform at its best for you. Here is why you need to change your car’s filters, as well as some of the common filter types.
A filter’s purpose is to remove small particles that shouldn’t be there from fuel, oil, and the air. Airborne particles like dust and dirt can scratch the inside of your cylinders and make your engine lose performance over time. Dirt and metal particles in your oil can quickly cause the oil to break down, clog oil passages, and ruin delicate engine surfaces like bearings. Dirt in fuel can enter the system and clog fuel injectors or carburetor jets. With modern (and expensive) high-pressure fuel injectors, it is even more important to filter out impurities.
