2012 Chevy Express 3500 Duramax
How often do most of you change fuel filters on your diesel engines? The owner's manual calls for 22,500-mile fuel filter changes, the Chevy dealer recommended 10,000-mile filter changes. I've read a couple of articles and some guys are recommending waiting until the computer says to change the filter. My computer currently says the filter has 72% life left in it, and the filter has about 13,000 miles on it.
