Fuel Filter

Most people do not often think about changing their fuel filters these days as a part of routine maintenance. This is because your car’s fuel filter lasts much longer then it did 30 or 40 years ago due to many reasons, such as the use of unleaded gas (to learn more, see my tip “The Modern Tune-Up”). In the old days, the fuel filter might need to be changed every 10 to 15,000 miles! However, modern fuel filters can last significantly longer, some past 50,000 miles. While the longevity of modern filters will save you time and money, the fuel filter should always be changed at about this interval unless specified otherwise by the manufacturer (often, the maker does not give a specific date for the filter to be changed). The fuel filter is very important to your car, as it keeps debris and other deposits from entering your engine through the gas it burns. A clogged fuel filter can hurt engine performance and gas mileage, and will eventually lead to more serious problems. As your car gets older, say over 6 or 7 years, the filter should be changed more often (possibly every year). This is because the fuel tank can corrode and build up debris inside over the years, which can clog the fuel filter significantly faster. For more information on your fuel system, see my tip “Fuel Injectors”.
