* Fuel Quality: If you consistently use lower-quality fuel, you may need to change it more frequently. Poor fuel can contain more contaminants that clog the filter faster.
* Driving Conditions: Severe driving conditions (lots of stop-and-go traffic, towing heavy loads) can also necessitate more frequent changes.
* Visible Signs of Clogging: If you notice a decrease in fuel economy, rough running engine, or difficulty starting, it's a strong indication the filter is clogged and needs replacing.
Ultimately, consulting your owner's manual is the best way to determine the manufacturer's specific recommendation for your vehicle. While the 12,000-15,000 mile range is a good guideline, your manual might offer a slightly different interval or additional advice.
