5800 Miles and DPF plugged?

Hello all-
Anybody else had an issue on their DPF plugging? My truck now has 5800 miles on it and got a display warning today saying: Exhaust filter plugged, Read Operators Manual Now.

Granted, its winter time and I let the truck warm up for 15 minutes in the morning. Is this the problem? Too much idle time causing filter plugging. I just cant believe that with 5800 miles (all have been of highway, other than the warm up idle time during the last couple weeks) the truck is have DPF already. Thanks EPA!

What do you guys/gals think?

All miles have been on or off highway??? Do you use the elevated idle??? Any mods or fuel used besides ULSD???

Any not approved fuel additives?
Is your oil CJ-4 approved?

5800 miles does sound early for a regeneration.
Did you let it perform the regeneration?

Not good to idle the LMM for long periods. I've let mine run maybe 5 mins top, but when its cold, start, let oil pressure build and start out easy til I get heat. I live 3 miles back in the woods so by the time I get to the main road I've got heat. I use the winter front all winter!

If you got the "see owners manual message," you need to drive the truck for about 20 miles over 30 mph. That will cause the engine to go into a regen cycle and clean the DPF.

Under normal operation the new LMM engines regen about every 380 - 400 miles (once a tank full).

If you are using a programmer or box, you are causing excess soot and the DPF will need regening more often.

Also stated if you are not using a CJ-4 oil, more soot/ash is produced.

If you are still able to find ULD fuel, this may cause more soot also. Need to be using ULSD.

Thanks for the replies. The truck is bone stock; no chip/programmers/etc. Also, only had ULSD in the truck since new. I drove about 10 highway miles hard and the warning display went away today. I will be making another hour trip tomorrow to verify the DPF is cleaned out. Also, I need to fess up regarding engine oil. My preferred engine oil (Deere 15W-40Plus50) is currently refined at CI-4 until mid 2009 when our Deere Tier4 engines are being introduced. (Kind of bias, but I am a true believer in this oil. I do not want to start an oil war, but I have witnessed oil/viscocity breakdown in some of other oils in lab tests. Ironically, I just put together a little feature/benifit story on our oil today... www.landmarkimp.com/oil )

Do you suppose the higher ash levels of the CI-4 oil is the cause of premature DPF problems? I imagine I should switch to a API CJ-4 to handle the soot/ash level requirements of the LMM engine until Deere begins making their CJ-4 available. Thanks again for the replies. Truly appreciate it

I would definitely switch to a CJ-4 oil and soon.
"They" say CI or CI-plus has to much ash and sulphur dissolved in the oil and can contribute to DPF plugging. Also the new emission trucks have much higher EGR flow rates to combat NOx this will most likely increase oil acidity and the new CJ-4 oil are supposed to resist this TBN depletion.

I don't think you're doing yourself any favours using your special oil.
I would omit your using a non specified oil if you require a trip to the dealer.
