So just to add to this thread, 3 days ago I added the archoil fuel system cleaner to half a tank and then topped it off with more fuel. My DPF gauge was at about 37%, it usually hits 45% and an active regen in about 2 days of my commuting after that. So you can understand my daily drive - 27 miles one way, 22 miles on the interstate @80mph, occasional stop and go driving, total 54 miles daily commute, no towing. My DPF gauge has steadily decreased and as of this morning it was down to zero and 355 miles since my last active regen. Non towing and achieving passive regeneration on my daily commute does not happen very often, I usually have to use aggressive throttle after my jog on the interstate to drop the DPF gauge any. In short, passive regeneration has been very easy to achieve. I don’t have any way to monitor egt’s or any other parameters other than what I can see on the dash. I have yet to use the daily treatment and will use it on my next tank of gas. But as of right now, the archoil is working as they claim it does. Not saying this is the magic bullet, this is just for informational purposes and how my truck has responded to the additive. I bought the cleaner and additive off of the Zon.
YMMV.
