DPF Level % Reading
New to the world of diesels. Got my 2023 2 weeks ago, and love it. I was looking through the gauges and noticed my DPF showed 35%, and it climbed slowly over a few days to 55%. Yesterday we set out on a 200 mile trip with our 7,000lb travel trailer in tow. About halfway through the trip, the reading showed 0%, and stayed that way for the next 100 miles. I was not aware of any regen cycle having happened. No lights or different sounds. Just smooth driving and awesome towing. Is this normal? Does highway driving clean the DPF without regens? Before heading out, I did fill up and added a bottle of Archoil 6400-D fuel system cleaner, as well as a shot of Archoil 6300. Could that have helped that much?

Highway speeds, especially working the truck with towing, will get exhaust temps high enough to perform passive regens. Around town driving usually does not get EGTs up hot enough, so if the DPF is filling up the truck will perform an active regen, which for the 2023+ means injecting fuel via a 9th inline injector and lighting the fuel to get temps up to burn off the particulate.

I also have a 7000lb TT that I tow with my F250 diesel and that will definitely do passive regen. Your truck will do a regen about every 500 miles and you will never notice it unless you have your windows down and are driving local streets. There are no lights or notifications and the regen takes about 10 minutes regardless of what type of driving you are doing. Frequently when I tow, with over 6000 miles, the DPF rarely gets over 20%. When the DPF is at 0% it can take well over 100 miles for the percentage to increase from 0%.
Edit: I also do not use additives and there is debate over if the really do much or not.

All great info, thanks folks! This truck is such a huge step up from 2018 F150 with the max tow package. I've never felt safer and more in control. And everything is just so effortless!

So there is no banner to pop up like on my 2015 that tell you it is cleaning the DPF? One of my biggest complaints is the regen. If you don’t see the banner, you don’t know it s cleaning. I always try to drive long enough for it to finish, when I can. I monitor my EGT’s with FORScan so I can know when a cleaning is finished and the exhaust system has cooled enough to shut down the truck. I’m thinking of buying a ’24 and was hoping there would be a gauge or indicator to let me know these things. SMH at Ford Engineers.

From what I've experienced, the truck will perform an active regen every 497 miles whether the DPF is full or not. I've also heard that it will initate a regen if the DPF hits 95%, but unsure as my DPF has never gotten that high before I hit the 497 mile trigger.

23+ has a completely different Regen cycle than the older trucks. First it uses more DEF, which appears to cut down some on soot, second, instead of injecting fuel on the exhaust stroke, they added an injector that sprays directly into the DPF so it uses less fuel, third they changed when it regens. With the miles setting, it regens when there is less soot built up, so uses less fuel to clean. Under empty highway driving, it wont accumulate as much soot as prior trucks did, coupled with the 498 mile regen timing (I do think it increases over time or decreases, based on how it is driven), soot levels rarely go over 38%.
When towing, more soot accumulates, but temperatures in the exhaust will also be higher so it will passively regen without adding fuel. I believe Ford figured out how to utilize DEF to also clean out the DPF. Also when performing the regen, on my iDash, it will not show it as active or on even though I can see the exhaust right around1100*.

My current 2024 (2nd one, long story) only has about 700 miles so far. The truck has gone through 1 active regen in that time. By 300 or so miles, the DPF read 75%. I went on an hour and a half highway drive to try and get it to passive Regen, but all I got out of the effort was an increased reading of 85%. Yes, it went up. Outside temps were in the 20-30 range and speeds were around 55-70 mph. I crossed the mythical 497 mile mark and then some with no Regen. Over the next few days it increased to 100% at which time it did an active regen. I was watching the DPF reading the whole time, and it went down to 0 in about 7 minutes. It has not moved off 0 in the week or so since.
My previous 2024 I never saw it do an active regen - it never got over 65% and usually hovered in the 30s. That truck had 2000 miles before it got traded in on my current truck. First one had a June 2024 build date and the new one was November.

From the 2023+ coffee table book:
During stage 2 regeneration the PCM commands a late injection in the cylinders of the engine during the exhaust stroke
as well as fi ring the DSI for DPF regeneration. This causes the DOC to create more heat burning off the buildup and
cleaning the SCR.
Diesel Oxidation Catalytic Converter (DOC)
The DOC is a ceramic catalytic converter which oxidizes
hydrocarbons in the exhaust and generates heat for the
SCR and DPF to function properly. In order to keep the
DOC from excessive sulfur buildup the PCM occasionally
performs a stage 2 regeneration.
This still makes me wonder if the 497 interval is part of this.

Thats for trucks up to the end of MY22. 23+ use a different strategy since it injects fuel directly into the DPF, no longer using the exhaust stroke for the fuel source. There must be some reason for the 500 mile regen window. I had it happen last night on the way home. Again, it did not trigger the iDash that it was in regen, I found out when I looked at my trip economy and saw it dropped, then glanced at the iDash and saw the EGT were running 1100*. DPF never goes much past 30%.
Unlike my 2019 that took 30 miles to complete and NEVER went below 4%, this one takes it's time to build up, and does not regen at exactly 497 miles, but over time I noticed the distance grows. Probably more of the adaptive learning.
Edit: Upon looking to see if there is any information on the 23+ cycle, I discovered the quick and easy way to find places for deletes, Just put 2023 6.7 dpf in the browser. All kinds of places selling delete kits and tuners, but not ONE example of what the 2023 6.7 DPF does or looks like.

I watch and track them all on an Edge monitor in the truck. Like clockwork 497 miles.
as you said it signals that it’s in regen for a little bit before it heats up and really starts decreasing the percent soot load. Once it actually heats it get cleaned much faster than the old trucks.
always goes down to 0% as well.
in regards to egt my 23 doesn’t get real high ever regardless of regen status.just figured it was because of the 9th diesel injector they use now.
