When Should I Change My Fuel Filter?

Your fuel filter is an essential part of your vehicle's fuel system, and it does precisely what you think it does: block out the dirt and grime in your fuel so that your engine can receive clean energy. Over time, this filter will get dirty and become ineffective. The problem with a clogged fuel filter is that it won't properly deliver the right amount of fuel to the engine. And when this happens, your vehicle won't get very far and not efficiently.

Besides poor engine performance, you may notice the following signs with an ineffective fuel filter:

  • Rough or shaky idling
  • Difficulty starting your vehicle 
  • Engine sputtering
  • Decrease in MPG
  • Check engine light on

A dirty and ineffective filter will also allow dirt, contaminants, and other harmful gunk to stir up all sorts of engine trouble. Once the filter's porous materials get clogged, you will need to replace the fuel filter. 

How Often to Replace Fuel Filter

Older vehicles typically require a fuel filter change every 30,000 miles, depending on the manufacturer's recommendation. However, modern cars nowadays can go slightly longer without needing a replacement. You can determine when to get your following filter change by having a professional mechanic perform a fuel pressure test. This assessment determines how much PSI the fuel pump produces.
