Cadillac STS Posted March 22, 2005 Report Share Posted March 22, 2005 Im just wondering at what point should you change your fuel filter? And how much should it cost to get it replaced at a shop instead of doing the work yourelf? Will gas mileage improve? Thanks Link to comment Share on other sites More sharing options...
JimHare Posted March 22, 2005 Report Share Posted March 22, 2005 I have done mine twice in 65K miles, so I'd say maybe once every 30K or so? The cost is minimal. In my 99 Deville, it's down just in front of the gas tank on the drivers side. Last time, J/Lube changed it for me. Cost about 15 bucks, probably. Mileage improvement will be negligible. Unless fuel filter technology has changed considerably since last time I looked at one closely (1973 Chrysler Newport with the 318), the filter is there to stop the random sludge and/or impurity from getting to your sensative injectors. Depending on how grungy your gas is, it may last for 100K miles before the filter material gets gloopy enough to change. Or, if you regularly fill up at Pedro's Pemex y Haciendos de Pancakes, it may require changing monthly...
