As I always have said my truck often idles for more than an hour and I have been saying this for almost 2 years now and have not had any DPF issues to date
i still think it's the fuel and the mom and pop stations that sell cheaper LSD and label them as ULSD. There was once a thread by a fuel delivery driver who said he has been told to fill the tanks with LSD even knowing they had decals claiming ULSD to save on the fuel cost. To this date LSD is more common in the Washignton DC area than ULSD
i am very careful where I get my fuel from. CHrysler has been teaching the tech's that work for me that most of the fuel issues is in the south west area of the US
