* Fuel Quality: If you consistently use low-quality fuel, you should change it more frequently, perhaps every 10,000-15,000 miles. Contaminants in the fuel will clog the filter faster.
* Driving Conditions: Severe driving conditions (lots of idling, dusty environments, off-roading) can also necessitate more frequent changes.
* Visible Signs of Problems: If you notice a decrease in fuel mileage, rough running, or hard starting, it could indicate a clogged fuel filter and a need for immediate replacement.
It's best to consult your owner's manual for the manufacturer's specific recommendation, as it might provide a more precise interval based on your specific vehicle's configuration. If in doubt, err on the side of caution and change it sooner rather than later to prevent potential damage to your engine.
