For my 2006 I do it every second oil change. For me, this averages out at about 14000-15000 miles between fuel filter changes. If the DiC indicates less than 20% life remaining I change it regardless of how many miles remaining to reach 14000/15000 interval. I'm not comfortable running a fuel filter too low a % life.

As others have said I too carry both a spare fuel filter for when they are not readily available.
