Another Regen question
Most of the time I can’t get my dpf to 0% after a regen. I’m usually between 30-50% full.
Any stats out there that prove a decrease in dpf life by continuously only being able to clean the filter partially? Or is this of no concern?

Is that because you dont have time to drive it down to 0%?
I dont know the answer to your question, but I think it just makes for more frequent regens, and whatever negatives come with that. Like worse fuel mileage.

If you are driving long enough to do a full regen but not dropping to 0 as you say, there is a problem. Are you able to force a regen with forscan?

The lowest I’ve ever gotten mine down to was 15% according to my dealer activated ghost screen in my ‘15. That’s when I was towing as well. If I’m not towing, 25% is about as low as I can get it. However, the DPF Soot Load % on my Banks Derringer will go all the way down to 0% before the regen turns off. If you aren’t using it, I highly suggest using Better Diesel FBC. I’ve ran about 600 treated gallons of diesel through my truck since I started using the FBC, and I have noticed an increase in fuel economy, as well as faster regen times, better passive regens, and more 500+ mile activated regens.

Mine runs up to 101-103% then regens down to 20%, then turns off and the residual heat burns the DPF down to 15-17%. That’s the best I can do. I have 69k miles and it has been operating like this since 25k or-so. 2017 STX. Haven’t seen zero in quite a while. Avg distance btwn regens is 310-320 miles.

Zero is an absolute, I would not think it to ever read 0... just the process to get it to 0 seems like it would be hard on the components. Also, if it did read 0, I wouldn't put it past some goofball lawyer to cut a filter apart, rub his finger across it, come up with some ash residue and then sue Ford saying "it should't show 0%"

According to my DPF % screen my truck gets to 0% most of the time. Unloaded on the highway or towing, both get down to zero as long as I let the process complete.
I am using Better Diesel FBC and that may have something to do with it. My miles between regens are right up there at 500.

I'll force the truck to regen only when I'm ready (Forscan), mostly on interstate runs of 70-80mph. In doing so, it has plenty of time to get super hot and waste all my decent mpgs... and it always gets to 0%.
How long it stays there is another conversation, but it'll get to "0% FULL" every time I let it complete a regen.

Mine also goes to zero as long as I drive long enough to let it finish or do a forced regen. I have noticed that I get more mileage between regens after doing a forced regen, around 400 with an active regen and closer to 500 with a forced regen. 54k miles on mine.

Another question would be how does the system "gauge" a percentage based number? A sensor that measures back pressure number? I honestly do not know but I bet someone on here does. What I do know is that no one on here believes the "lie o meter" that tells our MPG, why get hung up on a "0" number?

I only have an Edge CTS2 to monitor my regens, not the dealer enabled or forscan screen enabled and the lowest I have ever seen after a regen was 9%. That took approx 30 miles towing my 14K pound trailer. If i'm unloaded it will usually regen for 20 miles or so and get into the low 20% range or high teens if I'm lucky. My regens happen pretty close to 500 miles. My CTS says average regen distance is 459 miles at the moment. I would be curious to have the other screen enabled from Ford to compare the two. I might very well get to 0 on that screen.
