Not gonna lie, At this point in the game having owned or dealt with trucks (and even worse the stealerships) from all 3 and all of their respective issues - If Toyota would come out with an HD truck I would seriously consider giving it a go. I don't see how it could be any worse than Guberment Motors, Fix Or Repair Daily, or Faillantis Euro Trash - I've seriously become salty AF when it comes to these auto makers lol. One might point at the turbo 6 bangers eating themselves, but at-least Toyota seems to be owning up to it with the recalls.

Taking a wrecking ball to the brand. Sadly, it might be time to jump off the RAM ship, no good will come from this.

I have to agree with you on a lot of points, but Toyota hasn’t even figured out how they’re gonna fix replace Repair or make 100,000 truck owners happy at this point. From what I’m reading it’s a total engine replacement.

Toyota and their new turbo engine platforms are proving to not be as greatly engineered or manufactured as people would believe. The era of the durable and almost indestructible Toyotas appears to have come to and end. Watch Car Care Nut’s youtube detailed review of an iforce 4 cylinder. Plastic bolted to the engine everywhere to the point it’d make BMW blush.

Gross.... Man I really haven't kept up with gas stuff, but that's just depressing.

Did their tune disable the 24 hour driving time automatic regen? If not, the gauge will still rise. This is one thing I learned having the CTS3 Edge. The onboard (and CTS3) DPF percentage full PID is not just based on actual soot level, it is also based on the driving time.

When I start to get those to my 24hr regen the gauge starts climbing. I can detect this by looking at the last time it regened (use the driving time screen and subtract) and the PIDs that show time since last regen.

I really wish I could find a pid that truly indicated soot level and not the "timer". Apparently the WiTech can pull that but CTS3 does not (yet that I can find).

I have never seen the dash gauge change based on the 24 hour clock, it's soot based only. I can watch my PID % with my CTS3 and it will start a regen at 24 hours (100% on the CTS3) and the DPF screen stays at 0% (when soot loading isn't occurring) and then says active regen in process.

You are likely seeing soot loading rise, but not enough to trigger a soot based regen. The dash gauge showing above 0% is a coincidence when the 24 hour regen hits.

Here are the PIDs I monitor now religiously:

(Some of the PID names are cut off, when my CTS3 gets back from RMA repair, I'll post the correct names):

PF_REGEN_AVGT = Minutes since last Regen. This lets me track the 24 hour regen cycle and if the truck is "happy". This value should be close to 1440 minutes (24 hours) if passive regen has been working and we are only getting the timed reged.
PF_REGEN_AVGD= Distance since last Regen

These PID's are inaccurate. I have tracked every regen since new and neither of them are even close. There are other threads on this as well.

Here is some data I posted off of my CTS3 and regen log.

Regens at alarming rate!

How are you monitoring rail pressure and boost? If it’s thru the OBDII port then you are seeing what the module wants the ECM to see, not what’s actually occurring in the motor. While I don’t know the inner workings of that specific box it appears to be a fuel pressure with boost fooling. That...

hdrams.com

PF_REGEN_P = Percentage before next Regen (100% = Regen about to happen). I set mine with a warning at 90%.

I had mine set to 90%, but under a 24 hour based regen that's still 2.4 hours ahead of a regen, so I changed it to 98%. Even 98% has been fine for my couple soot based regens since adding the warning.

DPF STAT = Switches to ON when a Regen is in progress (again I set a warning but I can't yet get it to work properly)

There is also a green LED that illuminates when regen is active.

DPF Press = This should be the key value determining soot load.

Yes it should be, but I believe something is off on the tables that use DPF delta psi to determine soot loading. I think exhaust temp is one of those parameters with issues.

EGT1

EGT2
EGT4

EGT 3 is the most important EGT to monitor for DPF reasons. EGT3 is what will tell your DPF is cleaning, actively or passively.

Tell me about it. I buy a new car every 10 years or so and started researching for a new one a few months ago. To say im astonished at how bad vehicles have gotten from a durability standpoint has me crying myself to sleep at night. Thankfully i havent read any bombshells about Cummins cutting costs to the point theyre making throwaway engines (I’ll leave out the Nissan V8 debacle), but everything else is a grenade and the pin is pulled as soon as the ink is dry on the purchase contract.

The new income stream for manufacturers from selling telematic system user data is damn near criminal, and you cannot legally 100% opt-out in the USA. People need to Wake the F Up.

Well, my truck went from zero on the DPF gauge to four segments over the course of about 100 miles of unloaded highway driving today. It's never done that before, but the gauge been bouncing around a lot because I've done a bunch of intermittent towing since the last active regen. Anyway, it's been over 1000 miles/19 hours since the last active regen, so hopefully it'll settle down once the next active regen occurs. And I'll probably throw some Archoil in there; I figure it can't hurt. I won't be towing anything for a while so I expect the soot loading will accelerate shortly. Yay!

Thanks to everyone who's looking at the data and trying to get to the root cause of this issue. Hopefully you guys will find a smoking gun eventually since evidently Stellantis can't.

I ran the Archoil cleaner first and had a regen 40 miles after putting it in. So far I’ve got 533 miles and 12 hours since that regen with mostly in town and short trips and the DPF gauge is still on zero. I think it cleaned something out from somewhere. I’m using the every tank Archoil now and running Walmart fuel.

I think my truck is doing like it’s supposed to though. I’ve had a total of 19 regens since new and just turned 15K miles. 11 of those were at 23, 24, and 25 hours. 1 af 21 hours and the rest 10-15 hours.

 

[oledirteh]

my gauge is at 0% at 480 miles / 12 hours of drive time. however i just towed 300 miles of that so my results are skewed. i didnt add any on the fill up home yesterday, ill add some thursday when i fill up. i was going to do an oil change and fuel filters at 100k, but prob doing it this weekend at 99k just because this trip was a hard tow for the rig.

 

[WXman]

Reading this thread all that comes to mind is how it's such a shame that an engine that was legendary and would last forever with almost no issues at all has been completely ruined by EPA rules that don't even accomplish any benefit. Truck owners are getting screwed.

I hope the OP gets solutions that last and his problems are worked out.

I try to do my oil changes right after a regen. It probably doesn’t matter but it puts 1 less regen on the new oil change going forward.

yea, i run amsoil synthetic and was just looking and i changed it on 5/20 and have maybe 2500 miles on it, going to hold off. but just ordered the Mopar filters so I'll do that this weekend. my oil stays consistant and doesnt smell of diesel so im gonna say ill wait until my trip to new York to change it. i thought it had been longer, but now that im thinking about it i id it at 97000 miles. i can wait a bit.

i did order 2 bottles of the archoil diesel cleaner, so ill pop that in on friday after i top off then next week add the other archoil again once i run the tank low. im currently saving up to get the big tank (I think its 58 gallons) so i dont have to stop as much when towing. also maryland fuel prices are like 80 cents cheaper then PA prices lol id save a good bit

I have a 60 gallon auxiliary tank and shop for cheaper fuel also. With the auxiliary tank I can filter the fuel before it goes into the truck tank. I haven’t had any trouble with fuel dilution either but I keep an eye on it.

Regeneration & Archoil Updates:

The truck is now 521 miles and 13 engine hours since the last active regeneration completed. DPF % on the dashboard gauge is still showing 0%. (Last two regen cycles never made it beyond 350 miles). I had one brief instance where it climbed one “notch” (or what I would equate to about 12.5%, but it very quickly dropped back down to zero after some highway travel). DPF % REG on the iDash is now at 57%, which I equate to the number of engine hours surpassed (slightly over half way to a 24 hour regen cycle). I’ve now fully depleted the fuel that was initially treated with the archoil AR6400D fuel system cleaner, logging 593 miles on that fuel. When I filled the tank, I added the archoil 6500 diesel treatment at the recommended 1oz. Per 10 gallon rate. I’ve now logged 118 miles on that fuel. No sign of any performance changes. Everything still working well. EGT’s are still staying slightly higher and more consistent across sensors 1, 2, and 3 and the truck is running very smooth. No noticeable improvements in fuel efficiency, but definitely a vast improvement in terms of regeneration and soot-loading in the emissions. I’ll continue to update.

 

[oledirteh]

this is where im at right now. I have to fill up tommorow and my diesel clean wont show up till late tommorow. so may fill up today and just add the other archoil additive and run another tank then use the cleaner on the next tank.

I didnt add any archoil to the last fill up as i was towing.

I’ve experienced the same, other than I have no way to monitor EGTs. I’m on my second tank after the cleaner, using the daily treatment at 1oz per gallon. Passive regen happens much easier, not worried about mpgs, DPF soot loading was my main concern. I did just hit a 24 time based regen and it seemed to not take as long, I clocked it at 16 minutes. I have never been able to accomplish a 24 hr timed regen not towing and I’ve noticed that the DPF gauge has not even registered any soot load in the last few days during my daily hwy commute. Apparently it cleaned the DPF real well with the additive. I can’t help but feel this is how the truck should operate. As always, YMMV.

Edit : Just want to add, with the metal flapper at the top of the fuel neck, it’s a PITA to put in the additive - just sayin.

Seeing the pics on the Archoil website, it would be awesome to see a regular joe take pics of their injectors and turbo before using and after to see if it really did anything like those pictures show. However I suspect it’s a nightmare to get at the injectors and even worse to get at the turbo, maybe one day.

I'm 100% gonna give it a go myself after I run out of HSS EDT. Since I've been filling up a lot more in non TXLED counties - It's not nearly as effective it seems as when I was blending TXLED/non TXLED fuel just by virtue of filling up in both areas of the state depending on where I was when I needed fuel. I've had to start running double the perf dose to keep the DPF from soot loading.

I carry an additive funnel in my toolbox - you should also have one from the factory under one of the seats.

I saw that and had forgotten all about it. Thanks for the reminder.
