Fuel Filter
My new '13 D/A has 8430 miles on it and the filter indicator has 83% left on it. On my previous D/A I always changed the fuel filter every 15,000 miles and usually had 25-30% remaining. Anyone else s...

Most in the know don't go by the DIC. Change it every 10K. Yes its likely overkill but having your fuel system take a dump is upwards of $12K in repairs. WHy chance it over a few bucks. Cheap insurance IMO...
You guys waiting 25K miles are taking a big risk but to each his own.
Pickup up a fuel filter access door (ebay or diesel vendor) to make changing the filter a breeze.
:h You do realize that a dirtier filter filters out more contaminates than a clean one don't you?
Look at it this way; as it comes from that factory a new filter has lots of holes in it. Over it's lifetime some of those holes get pugged all the way, and some don't get plugged at all and most get plugged in between the two extremes. When they do get somewhat plugged up it will filter better because the holes are smaller.
As far as why the longer change time maybe the new engine reads differential pressures between the inlet an outlet of the fuel filter? I know on my LBZ the filter minder goes off exactly a 15K so I don't "think" there is a differential pressure sensor on the filter of my truck an it's just mileage based.
Where as the OMS drifts around 10K as it does have a algorithm in the system.
No, filtration is based on the micron spec for the filter media not how much******is in it. More******only means reduced flow, not extra filtration.
By running a clogged fuel filter you are running the risk of starving the CP4 fuel pump making it have to work that much harder to draw fuel from the tank. If your CP4 takes a dump it usually takes your entire fuel system down with it including injectors.
you need to educate yourself on GM's new fuel filters.
