Edge Insight soot count

I've been wondering why it appears that most post that talk about the Edge Insight monitor Soot Count and not Soot Load. For me, my brain can wrap itself around 0-100% (Soot Load) easier than looking for a number to reach 2.67. What am I missing? Is there something better about or is there more embedded information in looking for 2.67 (Soot Count) to know when a DPF regen is about to begin? Just wondering.

It is just a preference thing really. I have watched both and I prefer the GPL soot count because I am more accustomed to how it corresponds to how many miles I have until a regen will likely occur. Both the soot count at 2.66 and soot load at 100% occur at the same time. If you prefer one to the other, get accustomed to it and use that method.

The only time I really see a difference between the two is when working the truck hard and passive regeneration cleans the filter beyond the 0% threshold. I guess it is really of little consequence either way as long as you know how your truck behaves related to the parameter that you are monitoring.

As Matt pointed out, passive regeneration (and in some cases active regeneration) can clean the filter beyond the 0% threshold.

In the picture below, the DPF soot count is at 0.53. However, 0% DPF load occurred while the DPF soot count was still above 1.00.

Consider the GPL PID detailed information vs. a percentage overview.
If 2.66 is 100%, I've seen mine reach 2.74 before the regeneration began.
It's not important, I just like the information.
Plus as the others mentioned, you can watch the numbers fluctuate when towing or interstate speeds in the summer when not towing with passive regeneration.

0.53 is impressive. I've never seen a 0 in the ones place even towing and active regeneration at the same time.
The lowest I can remember is 1.12.

The fuel additive I'm currently using does seem to keep the soot count numbers down quite a bit.

Which additive is that? I haven't spent the $$$ on an Edge CTS yet, so I don't know where my soot count sits, but unloaded I'm in regen about 10% of the time (no issues when loaded up).

I just finished my first tank with Power Service Cetane Boost, but it didn't seem to make much of a difference in regens. My MPG did seem to rise slightly. Next oil change I'm planning to do myself with Valvoline Extreme Blue (seems to be the oil of choice here), and I'm switching to Chevron fuel from AAFES (Army/Air Force Exchange Service... not sure WHO they get their gas from). I tried Chevron & Shell last summer with no noticeable improvement, but didn't stick with it for more than 1-2 tanks before going back to "cheapest bidder."

I should probably mention that's mostly HIGHWAY miles that gets me to 10% average regens. Much worse if just driving city.

I watched that thread also, was just to lazy (and couldn't remember the name of it) to go back and find it. After a tank or 2 of changing diesel brands, I'll order if I don't see any improvement. Like I mentioned in that thread (I think), the truck isn't used as a commuter as much of late now that we have a 3rd vehicle... So it's not as big of a deal.

And when I tow, my passive regens are normal (ie, extremely rare events).

So, in the last 1800+ miles I've driven, about 1600 has been unloaded. Of those 1600 unloaded miles, I've been in REGEN 12.4% of the time, with an average time between of 82 miles.
