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 seeing this on their truck?

  • Peeps-My previous '06 LBZ usually had less than 25% at 15,000 miles.

    JustLabsThe '13 and '06 use the same AC part # so I would think-don't know-that they are the same. I assume that they would change the part # if they modified the filter.

    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?



    Lets not let the facts get in the way of a good rant...lol

    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.

    I have 25K on my 6.7 Ram. May change at next oil change.


    Just a note, your in-tank pump may very well have a shortened life by extending FF changes.

  • I have heard from someone who has put miles on a LML that the truck will easily go 40,000 miles between fuel filter changes.
  • My '11 has about 23K on the factory filter. I looked at the filter life the other day and IIRC it was at about 35%.

    The OEM filter on the LML is better than the filters used on previous models.

    I'll probably change it out in the spring.
