How often do I need to change a fuel filter?

You must change your vehicle’s fuel filter at 50,000 miles. Subsequent filters should also be changed at least every 50,000 miles, but changing them annually is even better. This is especially true once the car is at least seven years old, because rust, debris and other contamination builds up in the fuel tank and can clog the filter faster.
