DPF health??
So my wife's daily commute taking our daughter to school and then going to work she drives about 35 miles a day. Plus weekends add another 100 miles or so for the weekend. Our '14 Lariat with 85000 miles will regen three times in two weeks. It will go to 100% and when in regen it will drop to 0% (I have to DPF %screen enabled). Does this sound like a healthy system? I've only had this truck for roughly two months. Appreciate any insight.

Thanks. Yep she'll go to 100 % and you'll know when it's in regen, it'll start dropping and drop to 0%.

As mentioned in the "Exhaust Filter" thread, you might try a fuel additive. My truck doesn't idle much and only has 70,000 on it, I primarily use the truck for short around town trips but I pretty consistently get to the 500 mile automatic regen. My % full is usually in the high 90s at that 500 mile regen, sometimes it hits 100% full at the 490 something mile mark (497 twice, 498 once). When deciding on a fuel additive, look for one that boosts Cetaine. From what I read the higher the Cetane the hotter the combustion is which burns more of the fuel reducing the soot that makes it to the filter. It worked for me. I use PM-22A and since I started using it as I mentioned, I almost always make it to or close to the 500 mile mark.

The more city driving you do the more soot is produced the more regens will happen. Remember when diesels had smoke coming out of the exhaust when starting from a stop light? The same still happens but with the DPF it no longer comes out of the exhaust but the soot is still produced and trapped in the filter.

This morning while taking my daughter to school I noted the mileage at 100%, it regened down to 0%. My wife drives it more than I do so she's gonna note the mileage when it gets back to 100%. I'll update when that happens with mileage.

Remember if you drive it in town more than on the highway than it will regen more often. If you are worried about the frequency of regens than you need a car around town Just saying.
Not sure why you have this worry. Seems that the system is working as it should. I would be more worried if it wasn't.
All these gadgets to monitor your truck will make you worry. Whats the point of owning something that keeps you up at night?
If you dont work your truck than a gasser would have been a better choice. A 35 mile trip in a diesel isn't much. The transmission in mine doesn't even warm up in that distance.
Stop worrying and just enjoy your truck. If it ain't broke than don't fix it.

It's not a worry thing, more so a learning curve to know the health of the system. Nope don't want gas truck. My wife has a '14 Impala that we bought new, she just likes the diesel Lariat. Yep.. She's a keeper. I've done tons of research on the 6.7s and been getting my thoughts together on the dereet as well. The truck is actually in pristine condition and runs perfectly but my ocd insists that I know all I can about it.
P. S... I am definitely not in the "if it ain't broke don't fix it" group. 😁

Daily driving mine (I don't now) I would average an active regeneration around 260 miles. More distance when it was newer, less and less over the years. If EOT was above 150°F at 2.55-2.57 soot gpl, a fully driven regeneration would burn down to 1.35 soot gpl or so on the newer firmware (around 1.15 gpl with the pre 2014 or 2015 firmware).
I also recently learned a lot of soot is created lugging the engine in sixth gear manual. There is so much torque it easily handles small hills without downshifting. However, for eight years that wasn't helping soot accumulation.
The fuel system is absolutely far more refined and efficient than older diesels but I have no idea why I assumed it wouldn't slightly over fuel even though that's what I'm asking it to do with the accelerator to the floor. Same results manual sixth with cruise control.

When I first got my 2011 truck,, I paid attention to the regens. After 150,000 miles in that truck and another 100,000 in my 2015 truck.
I don't worry about the regens. They happen when they happen. If I shut down in the middle, They will start up again another day
If I'm towing and the truck is doing passive regens and my DPF is 5% or thereabouts and it does an active regen because I've hit the 500 mile mark.
I think, OH I'm wasting fuel. It didn't need to regen. So I'm happier if I just don't pay attention

I am one of the few that the filter will go to 100% and then back down to 0%. But I seldom regen at all with the towing and then my regens are short in duration.
I'd say your normal for your truck and use.

I have a Edge monitor system that I use to keep tabs on things. I have notices this summer, that the DPF load will hit 100% and the regen will start. It will do n active regen down to 30%, then the it will switch off. With the elevated exhaust temps, they DPF load will continue to 'burn down' to 15-20% (sometimes even close to 10%).
I have noticed that sometime the Edge unit is not in 100% agreement with the trucks on board displays.so if I have the DPF screen enabled it my show 0%. As an example, it is not uncommon for the transmission temp to be off by 2-3 degrees, even though one would think they would be reading the same PID form the computer.

I guess this is going to have to be answered with someone who has access to IDS and can read the exact data during a moving regeneration. Such as, is the dash programmed to make the non-enthusiast driver happy where 0% without towing temps avoids questions ("mine never burns to 0%, my truck must be broken") or are third party devices reporting incorrectly? Maybe it's as simple as Edge programs 1.30 soot gpl to be 20% as an example and Ford programs that to be 0%.

I don’t have the DPF screen enabled on the truck. I understand it reflects load and scales 0-100%. I do have the Edge, and it has “gpl soot” and “DPF load.” I think either of these can trigger a regen (along with the 500 mile limit). I’m suspicious the Ford screen is scaling these two parameters so that the “load” hits 100% whenever either of these parameters hit their setpoint.
On a side note, the “gpl soot” regen setpoint for mine seems to have shifted with mileage. It was 8.38 when new and now seems to be 8.88 or so after 25K miles.
