2023 6.7PSD Utilizes 9th Injector for Regens
I really like that Ford implemented a 9th injector for the regen process and is probably the main reason how they are now able to go 15k miles on oil change intervals.

It will probally save a lot of engine blocks….which is a current repair back order problem.
my take is that the fuel dilution and artificial oil generation which feeds oil must into the ccv ….further compounded by “let’s play the extended oil drain interval game” just results in super thin oils that provide little or no protection ….
hopefully this will reduce oil mist into intake…thinking of oils…higher confidence amoung those that want to play the extended oil drain game.

The new emissions strategy on the 23s seem to utilize more DEF and less EGR, which will keep the intake somewhat cleaner because it's the oil being vented into the intake by the CCV that when it meets the EGR (soot), that's where the crud comes from. I still don't like that Crankcase crap is getting sent back into the intake to be burned along with AF mixture...
Plus taking the extra regen fuel on the exhaust cycle for the regens out of the equation, oil life can go much further, for the "clowns" like me, according to ARod, who let their trucks tell them when to change it.

I believe this change is a huge improvement for the long term health of the engine and if I had a fairly new 6.7PSD and was planning on owning it long term, I would seriously consider trading it for a '23 MY.

I totally agree, this is a great step in the right direction if it works out. I have only had my truck for a little over a year but when the time comes I will definitely have to give the 2023+ trucks a good look.

I'd say its worth considering that the fact that Cummins continues to use the exhaust stroke method indicates that it is not necessarily harmful to engine longevity. Most agricultural and construction equipment uses the exhaust stroke injection method as well.
All that said, I prefer the additional injector method, but it does complicate things and increase costs a bit.

Ford hasn't had a regen notice since the 2016 model year trucks. What do you mean by "having to go this route?"

warranty issues with dilluted fuel, emissions systems failures due to the same.
You have a group such as us who are aware of the emissions systems/functions and can deal with it.
Then you have the average buyer who sees it, drives it and all they are told is every once in a while you need to add def. Nothing more is said. These are the folks that cause alot of issues.

Yeah, I understand that. But that's exactly how Ford wants it to be - the driver should never have to worry about a regen. I feel essentially the same way, although I like having the extra info and in the past used FORScan or the dealer to enable the DPF screen.
What is interesting to me is that my Kubota tractor tells me when a regen is occuring, and when it ends, and if my engine RPM needs to increase. Ford used to tell the customer that, and now they don't. The 9th injector really doesn't solve the main problem of DPF regens though, which is for the truck to be run long enough and hot enough to actually cook off the accumulated soot. The extra info is quite useful in that regard.

The RAM trucks with the 6.7L Cummins already have a 15k oil change interval, and have had that for years. They still use the exhaust stroke injection method for regens.
I'd say its worth considering that the fact that Cummins continues to use the exhaust stroke method indicates that it is not necessarily harmful to engine longevity. Most agricultural and construction equipment uses the exhaust stroke injection method as well.
All that said, I prefer the additional injector method, but it does complicate things and increase costs a bit.

I don't idle my truck much, keep track of regens and even though I daily drive her, in the hills south of Buffalo, 18 mile one way to work... She's fully hot when I get there, I still had a few UOAs that had a little fuel in it. Others came out either trace or none detected. If I had my choice, I'd say the 9th injector in the exhaust is the way to go...
And I bought and use a Banks iDash to keep track of regens. I'm not an average owner of a 6.7.

One problem is the "intelligent" oil minder system, which tells the driver when the truck (based upon manufacturer programming) wants an oil change. If there is a lot of idling or short trips, interrupted regens...that's fine but the OCI needs to be waayy shorter than the usual 7-8k miles that the dashboard will display.
