What has changed with how the 2024 trucks regen vs the 2020 model? I’m pushing about 1300 miles on her and noticed when ever the dpf is around 40-60%, the next day it’s at 0. I’ve yet to see it get higher than 70%.
The 2020 use to get at 100% then take about 20-30min to burn it off.
Appears the new truck is burning it off faster/ or doing more regens before 100% so it doesn’t take as long?

few things
If temps are up from highway driving it tends to passive regen
and active regen. Uses 9th injector right at dpf area so it gets hot faat and burns off
mine rarely gets above 45
Before it does one

Thanks!
With the regen performing like this now, will it cause the dpf to fail more prematurely, last longer or same life span?

good question
My bet is it goes further before it needs replacing..
ino
It seems the ecm is doing earlier command regens to maybe help with longer life since les build up is present
But hey . .I didn't sleep at holiday inn last night
I believe that on the 23+ MY the DPF should last as long or longer due to fewer to no partial regens due to the relatively quick regen cycle. DPFs fail mostly due to the accumulation of ash from the non-combustible components in soot, this can be from things like poor quality fuel, engine oil , and some additives that are not safe for DPF equipt engines.
The 23+ trucks will do an Active Regen every 497 miles REGARDLESS of the DPF filter Percentage. It might be 30% or 90% doesn't matter it will regen at 497 miles. This is different from your 2020 that would wait till it hit a certain percentage.
Because of the 9th injector. Regens are faster. Mine are usually done in less than 10 miles. and about 1/2 Gallon of fuel vs the older 25-30 miles to complete.
Like previous generation 6.7L They still do a Passive Regen anytime your EGTs in the DPF are over 572° So the truck just naturally seems to keep the DPF% on lower side, rarely do I see 70-80%
The 23+ trucks run 150-200° hotter than my 2020 truck did. Just watching the temps at EGT1. I assume these hotter EGTs help more passive regens. The hotter EGTs are the reason the 23+ trucks use more DEF to reduce NOx that is created at higher combustion temps. But the increase in fuel mileage more than offsets the cost of extra DEF.
I've noticed the EF % full is not accurate on this generation. The Banks gauge goes between 10% or 15% after a regen when the truck gauge shows 0%. Truck seems to stop the regen before a "true zero" is achieved. The Banks gauge indicates 100% and the truck gauge will indicate about 55% when a regen begins. Not sure what marketing strategy Ford is trying to achieve with this misleading information. My best distance to date, 422 miles on the last regen.
That 497 is not set in stone, it varies based on computational factors involved with how quickly the DPF fills, regens, average MPH, Fuel use, etc. I started counting regens based on 497, now its closer to 540 miles between regens. Of course YMMV. Now its to the point I never know when it will regen. Half the time I don't notice until the DPF is at or near 0%. Mine never goes over 34%.
This past week my % was hanging out around 80-85% and I was doing small quick runs to home depot so the truck never got up to temp. Took about a 45 minute drive this weekend to go for a hike. Arrived and was at 0%. I wouldn't worry about it. Just drive the truck and let it do its thing.

The bank’s gauge is indicating the dpf/regen trigger point(when a regen will start), not the particulate filter soot level. So your truck is showing a different value because it’s showing you a completely different parameter. The banks gauge has an option to show soot level, i believe it’s ‘SL %’ or something along those lines.

My guess is they stretched it out further w the older trucks since they were dumping fuel into the cylinders vs the 23+ that has the 9th injector. Probably to minimize wear on the bores. I don’t think I’ve gone above 0% during summer months and in winter it maybe gets to 40%. Fwiw I am in a hot climate and am mostly on highways. Someone else said it too that it regens at a mileage parameter regardless and I know I’ve been at 0% and been through a regen because of the distinct smell.

wrong. The 23+ trucks will regen like clockwork at 497 miles unless something’s wrong with yours?
I track every single one of them with a monitor and at almost 60,000 miles I can say for sure 497 since last regen triggers one every time.
the only accurate part of your post is that I agree you can’t tell it’s conducting a regen unless you’re watching tha gauges. Otherwise it’s pretty much unnoticeable.
They will regen at 497 unless their is enough soot to cause it to regen sooner. But if the soot load doesn't trigger an early regen. It will do it at 497. I'm also at 62,000 miles and watch it as it approaches 497 and know it will trigger. So I just plan my drives accordingly.

Maybe I need more downhill? None of my Ford's ever got close to that number.
I have had 2 2024 HO 450s and neither did auto Regen at 497. My current truck has made it to a DPF 100% full state on multiple occasions with around town errands that kicked off active regens, but I have watched a few times now where the DPF was between 60-80% at the 497 mark and even driving on the highway for an hour did not trigger a Regen as the miles soared past this magical threshold.
