Let me share my experience with the whole “making oil” and frequent regen issue. It’s a lengthy story but I’ll try to only include the important parts.
I have a 21 Ram SO. It worked exactly as it should until Last April (2023) never registered any soot load on the dpf and only did a regen about every 20-24 hrs to my knowledge. I changed the oil and air filter still had original air filter in it which was orange foam no glue strips and put a new one in I got from the dealer. Black foam with glue strips. I then took my truck to the dealer a couple weeks later for a recall and they told me they “flashed” the computer for latest updates.
About a month later was when I noticed it was doing Regens more often. About a month after this I asked the dealer about it and they just said some of them do that. I kept track and it seemed to me as if it operated on a timer. The truck would not go over 6 hrs without doing a regen unless I was towing my trailer. As soon as I wasn’t towing my trailer the dpf would shoot right up and go into a regen.
Then in August I checked the oil before a trip and I’ll admit I hadn’t checked it in about a month and a half and it was very high. I thought maybe an injector. Took it to the dealer the next day and they actually checked me in with the work order stating “making oil”. They checked the truck out and said there was nothing wrong, changed the oil which had about 4.5k on it and I went on my way. I monitored the oil after this and noticed it only gained oil after it performed a regen.
A month goes by I get a check engine light one day. So I drop it off at the dealer that night, next morning they call and say it was for the turbo speed sensor but that there was a new flash for the computer to help with my regens, and it did. After this it would go 12-16 hrs between regens which was twice as long as before depending if I was towing or not.
December I changed my oil again and sent a sample out. Came back as having <0.5 fuel dilution which was fine but it still wasn’t making it to the 24 hour mark between regens. It still was like clockwork the dpf would stay at 0 for about the first 8 hrs and then climb quickly and go into a regen at 12 Hrs.
Just about two months ago I changed the air filter(using the one without glue strips) and CCV filter (was oil logged) as you all recommended on here and now my truck is right back on the dot at 24 hr regens with little or no soot load on the dpf. And the truck acts like it used to. Better throttle response, better fuel mileage and no quick shifts with lugging, all things I had been experiencing. I guess my whole point is the filter is part of the equation but also the version of software the truck is running. That started the problems and then fixed them along with the proper air filter. Just coincidence that I had changed to the wrong air filter the same time the computer was flashed with what I will call very bad programming.
