<h4 class="dechead">On One Hand: Change As Needed
New cars don't really need to have their fuel filters changed that often. A quick examination can determine if it needs to be changed. Detach the filter from the carburetor, take a piece of clean hose and blow into the filter to see how easily air passes through the device. If it feels clogged or air doesn't easily pass through, then the filter needs to be replaced.
On the Other: Preventative Maintenance
Some mechanics recommend changing your fuel filter every year or two, especially for older cars where grime and dirt can build up in the engine. Using cheap gasoline with additives or driving on dirt roads can also wear down a fuel filter and cause engine problems.
Bottom Line
If you are a typical commuter that uses regular gasoline, physically inspect your fuel filter every 25,000 miles and replace as needed. If you have an older car, tend to use discount gas or drive on country roads, consider changing your filter annually.
