Does your Cummins regenerate once per tank?

sstoner911:
I do agree with some points you make in your replies, with the exception of your last sentence, we shouldn't have to pay an extra 6 grand or any additional amount of money for that matter to rectify or "fix" something that should be a non issue.
Agreed. I'd also be paying a lot of money to give up a lot of my factory warranty. Totally counter intuitive.
 
Comments like this are where you’re just trolling the thread and not providing the benefit you perceive you are.
I am not trolling, I am not sure what you mean "providing benefit" as my comments are just my opinions on the subject. Take them or leave them...

This issue of to frequent regens hasn't seemed to be resolved TSBs or no TSBs. My comments are to the member not having issues, so not sure any benefit was intended since they are problem free.

There is a huge amount of trucks operating between “as designed” and total failure. That’s where threads like this that educate folks are useful. It’s an expensive system that can be maintained far better than your recommended approach.

You say your 2022 didn’t have any issues, great! Many of them do. I’ve asked before and don’t recall being answered, but how many miles were on your 22 when you sold it? What was the average duty cycle?

All of my Rams are or were daily drivers with some towing. Towing probably only accounts for about 5000 miles per year. The 2022 had 50K when traded.

I guess the issue of "to frequent regens" can be subjective. Has FCA published the regen frequency norms? I see a lot of things being mentioned, every 24 hours or at 1033 miles. I even seen one guy mention his truck had 38,000 miles and it as NEVER regened(we know that is not true). A lot of folks say the DPF screen never moves off zero! You have to be watching that screen full time when you drive to see any regeneration messages or see that the soot level has gone up. Most people do not do that - some see it scrolling through the EVIC from time to time - some have no idea that screen exists.

I am sure some of you have seen this spreadsheet as ma here are members on multiple Ram Forums. It has been around since 2023 and has a lot of data - not sure if it tells you anything significant other than a lot of the trucks on this spreadsheet are not "fixed".


I see guys post their PIDs from various 3rd party monitors and say "look it regened in 18 miles!", but the info shows their regens are happening every 1200 miles or so.

So forgive my skepticism, I am just not sure there is enough hard data to pin point a solution - at least not from the general public research.

It’s an expensive system that can be maintained far better than your recommended approach.

I am guessing you are referring to my suggestion to delete.

It certainly is the more drastic approach, but a for sure fix. By maintaining what are referring to? Additives? FCA has no recommendations for maintaining the DPF.

There are a lot of factors that can prevent the truck from having successful regens - this one from the owners manual caught my eye:

"NOTE:
Failing to follow the oil change indicator, changing
your oil and resetting the oil change indicator by 0
miles remaining will prevent the diesel exhaust filter
from performing its cleaning routine. This will shortly
result in a Malfunction Indicator Light (MIL) and
reduced engine power. Only an authorized dealer will
be able to correct this condition."
 
Agreed. I'd also be paying a lot of money to give up a lot of my factory warranty. Totally counter intuitive.

Your warranty isn't forever, and deleting doesn't VOID the entire manufactures warranty. Just like adding any other aftermarket part doesn't. Some wait until the warranty is up some don't.

My 2017 2500 was deleted. My local Ram dealer addressed a lot of warranty issues, recalls and TSBs even with it being deleted. Some dealerships are a bit more hardline on this issue now, so I always tell people to wait for teh factory warranties to expire. The emissions stuff has a longer warranty period, but if the 3/36K mile is up and the powertrain is up - might as well consider it.

I still say for your situation, drive the truck, use some additives if you want, have the DPF issue in the back of your mind but don't dread on it every day. Just my opinion!

I need to read this in the manual as now I'm confused to what it is saying. If you let the oil change life go to zero before its reset the regen routine gets thrown out of sync or if you reset it before it gets to zero you throw the regen routine out of sync.
 
Your warranty isn't forever,
LOL. Yeah, I am aware.

It voids most of, if not all of, the drivetrain warranty.

If I was out of warranty entirely and having issues, yeah, it might be something to be considered. Glad you had a dealer that overlooked your delete. But I would not take that chance personally.

Well, I wasn't really asking for your advice. Just trying to address your cavalier attitude that the DPF problems are not real, or not fixable, or whatever point you are trying to make.

I think we are beating a dead horse here.

The only point, was its not fixable by the end user -

Yes its real for some...but not you...or me.

It means do not ignore you OIL Life screen and be sure to reset before it says 0%, otherwise the DPF will stop any regen routines.
 
Another update. My last Regen cycle occurred after 752 miles .
So, since using the Archoil 6400D I have gone from as few as under 200 miles per regen to in this last instance 752 miles. I
I have my fingers crossed hoping for an additional increase in miles driven. If not, I’m still traveling close to four times the amount of miles as I was prior to adding the 6400D.

Run the daily as well, it helps.
 
My truck went to the dealer over this today 22 33000 on it. Since my post in april about regening 1-2 times a tank it started regenerating about every 65 miles ( minimal idling and minimal short trips. ) and would constantly throw up the message automatic exhaust system regeneration in process continue driving. yes process wasn’t a typo. They called me and said they are replacing the dpf and it is about done but they will finish it tomorrow. I hope this is a fix and not just a bandaid , time will tell.
Good luck, our '22 is going in for it's 3rd DPF in 26k miles. I exclusively tow a 16k toy hauler.

They replaced every part of the emissions system along with the intake air box, turbo hoses with who knows what else and most of it's sensors.

It will be sold before warranty is up. Worst vehicle I've ever owned and now NEVER take it out of town unless one of our friends with a 5th wheel hitch goes with us. Disappointing, our '18 was a great vehicle.

Wowzer that is very sad to hear, it sounds like the only thing they have not replaced is the wire harness and ecu with new programing..

Hi, do you buy a consistent brand of diesel or use the same station each time ? Reading various information about diesel fuel, there might be some substantial differences in how well filtered they are.

Are you using conventional diesel, biodiesel or the new CARB stuff that is a mix of biodiesel and a higher cetane blend ?

For example

You talking about Renewable Diesel and it shouldn't be compare or conflated as any sort of biodiesel blend. They are not the same.

"CARB Diesel" (B0) and "Renewable Diesel" are NOT the same.

Renewable is made from similar sources of biomass but is chemically different than biodiesel. Renewable is chemically identical to Petroleum diesel.

While both renewable diesel and biodiesel are biofuels derived from renewable sources, they differ in their production process and chemical composition.

    • Production:
      Renewable diesel is produced through hydrotreating, while biodiesel is produced through transesterification.
    • Chemical Structure:
      Renewable diesel is chemically identical to petroleum diesel, while biodiesel has a different chemical structure.
    • Engine Compatibility:
      Renewable diesel is a drop-in fuel, while biodiesel may require specific engine modifications or blending with petroleum diesel for optimal performance.
    • Blending Limits:
      Renewable diesel can be used in higher blends or as a complete replacement for petroleum diesel, while biodiesel typically has blending limits due to its chemical properties.

Thanks - there have been various blends over time, some included biodiesel up to 20% and some had 20% normal diesel. I guess the Nanny's at CARB needed something to do so they changed it - again. :rolleyes:

@Resilient lives in the same general area that I do ( according to the location tag ) so that is why I am asking more details about the challenges ( and successes he is having.

If / when he finds a successful combination, it will give me more confidence in buying a diesel truck. If not, then I need to re-think things.

Ouch. I hate to hear stories like this. I also went from an 18 to a 22, almost identical trucks. I have 21k on the '22 and not had much issue so far, 90%+ towing miles. Hoping my luck continues. The 18 had no issues.

And I hope you have better luck with your next truck.

I'm really torn between ordering a '26 RAM or a '26 Ford. Been a MOPAR guy all my life but this new RAM has cost a LOT of good will. My dealer has been great but I have no doubt after a number of conversations with them they're being brutalized by Stellantis too.

Unfortunately for them it's the dealer that takes the hits over vehicles which have problems that even the manufacturer techs cannot figure out.
 
Another update,
My DPF with daily driving was showing almost to the point where it normally starts a regen.
I towed my boat and instead of going through with a regen the DPF gauge started incrementally dropping till it reached zero.
This seems to me the way it should function, passive cleaning under load.

That's the way it works on my truck, consistently.

I am up north fishing for a month. Towed the bass boat up. But not doing any towing while up here, and the truck is being used in the running errands/grocery getter mode. Went from 27 hours between the last 2 towing regens to 8. And the gauge jumped up again quickly after the 8 hour regen. Worrisome for the long term health of the DPF.
