There is a video on YouTube that I watched a few weeks ago where they took a 6.7L torpedo (the emissions system) to a shop that cleans DPF. It turned out that the DPF cannot be accessed independently of everything else.
Here's the video. Skip to 17:50 where the radiator shop says it can't be done.
You can buy a refurbished 6.7 DPF, so apparently it is possible to do. That shop? No. Clearly they can't do it. I don't know, but I suspect the shops that do 6.7 filers just cut the filter apart, clean it, and TIG it back up.
I've seen that video before. There are parts kits which allows the Filter section to be cut out of the big piece that then allows the DPF to be cleaned by itself as it is no longer part of whole assembly. That's what I meant. Has anyone seen that kit utilized and the Filter cleaned and bolted back up to a 6.7 rocketship? When someone does that or can do it successfully, they'll have a lot of business.
Posting for FYI... Have no experience or knowledge of what is done to it or if the kit I mentioned is used. I'll find the link for that kit and post up when I get a chance.

This is the kit I was talking about. Someone else posted it here awhile ago in a different thread. It's made to make the Filter part of the Ford rocketship removable so it can be serviced and/or replaced if need be.
Kper, so was that with all stop and go driving, or that was it that low with highway/hauling driving as well?? No wonder your truck lost weight if that's the case.
Mostly daily driving mix of highway and city and that's with monitoring data over the years like soot gpl (active regen) to try to ensure I complete one on purpose if I had cancelled several. Hauling the tractor to my land is 170 miles round trip and that would cause one active regen when I started having more and more issues. So, both I guess. It didn't matter much whether the truck was moving itself or 16,000 lbs.
In the end, my truck wasn't healthy for a few years, 2016-2018. I suspect it's several things. I had DEF system issues (could throw off the ECM calculations?), a fuel injector issue, discovered the EGR cooler core was clogged, smoking regenerations became more frequent and more recently I now think oil consumption possibly played a factor into the frequent active regenerations even though I don't see visual evidence of it in the exhaust hardware. I think the oil consumption was somewhat masked by the 3% fuel dilution because it wasn't obvious, which I realize is only 0.4 qt of fuel in the crankcase. The truck consumes 1 qt by 6,000 miles now mostly towing and I don't think that suddenly started because certain changes were made. What I do know, for the past three years it runs and pulls like it did in 2011 (except the HVAC has poor cooling now). If these are a daily driver, there is nothing further I know to do (or want to) to monitor systems better to have produced a better outcome other than living on an interstate always dragging weight, which isn't my reality.
Thanks for that explanation. Sounds like you most certainly did have issues. That's crazy that the regen interval was that short. Like I've always said, I feel very fortunate that where I live and how I drive supports the emissions routine and keeps it healthy without pulling a load. I don't let the truck idle a lot but will let it idle some to get EGT1 under 400 deg before I shut it off.
With yours burning a qt every 6k miles, are the exhaust tips black or do they stay clean? That's not a lot of oil.
Makes we wonder how the Duramax guys (if the guys on the forums are honest) ~500 miles between regens when the 6.7 Powerstroke was supposed to be so much more efficient.
Can confirm this statement. Switched to 21 Dmax as I got a smoking deal, at 2900~ miles and just finished 4th regen last weekend. Driving style is mixed, work from home so some times city driving or put on a couple hundred miles going out of town on weekends.
sorry I have no other value to add to your topic regarding the 6.7 regen frequency.
