Ok, I'm not sure what all of this means, but thought I would pass along the info and maybe someone smarter than me can make it make sense. My truck, 2022 tradesman has been doing frequent active regens, approximately 3 per tank of fuel since new. It has never done a passive regen even when hauling a heavy load for an extended period of time. The last 2 tanks of diesel I purchased from a different station that advertises the fuel is up to 20% biodiesel. The first time I purchased it was by mistake, but I noticed something. For the first time, the truck did a passive regen while driving and my dpf filter went from 30% to 0 without the truck going into active regen. Since that time, the dpf filter has stayed on 0, even though the last tank and a half has been all in town driving. The fuel being used now is produced by a small time local refinery that buys soybeans from local farmers and uses it to produce the biodiesel blend. I have read that biodiesel is not the best for these trucks even though it is approved for use by cummins. But, why is it making my frequent regen issue go away? Just for information purposes, the local refinery producing the fuel is Continental Refining Company, and the call it Ultraburn F20 Blend. For what it is worth, my fuel mileage seems to have remained relatively the same.
