- Just providing an update to everyone that has been following along. I will just accept the fact that the regens have increased and are currently not having a negative affect on my fuel mileage. I went from 400+ miles in between regens to averaging about 200. My mileage / mpg is sitting at 22-24 so I cannot really complain.

My 23 AT4 LZO was at the dealer last Monday and Tuesday for the frequent Regen issue. They had no idea as everything checked out. They opened up an incident report with GM, was told GM engineers have never heard of this issue but are looking into the open ticket. I told them to search TH-cam and message boards that the issue is common. I picked up the truck instead of letting it sit at the dealer while they figure it out. They are getting back with me this week to find out what the GM engineers say.
Thanks for sharing! Please report back when you hear something and please tag me @demonworks to make sure i see it!
@@DemonWorks yea the same thing happened with the 2.8 babymax and it took them months (to also believe customers) to release a flash fix that got it back up to ~400 miles per regen.
I have a ‘24 LZ0 and regens have all been roughly 350 miles. Everything is stock other than the iDash. I use Hot Shots EDT every fill up.
2024 1500 RST purchased in November 2023 has 3600 miles on it now. Regens are every 130 to 175 miles. My drives are typically about 40 miles on the highway.
So, I normally don't post on the TH-cam chats but I wanted to comment on this once since I've been following your videos regarding the frequent regens and wanted to contribute. Your channel is one of the reasons I got my Banks iDash and it has great content for the LM2/LZ0. Having the iDash has allowed me to plan my trips and complete full regens without shutting the truck down mid-cycle. I got my 23' LZ0 AT4 in December of 2022. At that time, I didn't have the iDash yet, so aside from being able to smell it (when it was new) I don't know exactly how far between regens I got my first winter. With all that being said, I added the iDash in June 2022. With the iDash monitoring, I saw I was only getting ~125 miles between regens and some were only 100 miles. What’s really interesting is that once the winter time rolled around I was getting 350+ miles between regens. Now that the warmer, more humid weather is back, my distance between regens has been steadily dropping back down to ~125 miles. I just completed a regen this morning and only got about 130 miles. I use Trip 1 on the truck for distance on a tank of fuel and Trip 2 I reset every regen even though I also have the iDash to show average distance and time between the regen. It doesn’t seem to matter if I run an additive or not. I also only ever run either Shell diesel or Irving and that also doesn’t seem to impact the regen distance. My truck is stock and fuel mileage is about the same as others with an AT4 or ZR2. (21-22mpg city, and 27-28mpg on the highway) I also have not really had any codes, fingers crossed, except for (2) P2C7A codes this winter which I attributed to more idling due to the cold weather and de-icing. I've also had a Snap-On scanner connected to my truck recently and nothing was out of the ordinary. I can’t really explain it but the truck seems to like the cold weather better. Sorry for the long post, but maybe this helps.
That’s nuts! I towed alot with my LM2 but i was averaging 637 miles per regen. Also 23.8 mpg lifetime on Fuelly with a ton of towing and hauling
I bought my truck in AZ and I was getting 400+ regens, once I started fueling in CA my regens went to 3-4 per tank 🤷🏻♂️
For what it's worth, my LM2 started having more frequent regens (every 200 vs every 400-450 before) after changing the air filter with a GM replacement and following the factory air filter life reset procedure. A few regens later, I cleaned the MAF sensor with CRC cleaner and it seems like things are back to normal.
Purchased my 2024 GMC Sierra 1500 AT4 on April 30th. The truck is completely stock with 1200 miles, and it has a regen every 100 miles.
Based on many peoples replies to prior videos, this seems to be the norm for many.
No idea how you were getting so high. New 2024, I get around 150 miles per regen.
2024 LZ0 trail boss with 8000 miles and I’m getting regens about every 100 miles now. Definitely was not like this when I first bought it. Had one regen per tank.
So many people saying the same thing. It's so weird!
Id run a fuel additive that will clean the injectors for a few tanks. Probably won’t solve it but won’t hurt.
Every jug of def fluid is another giant plastic jug in the ground..
It’s cheaper at the pump
Give this a shot, my friend: opt for stock AEM dry flow air filter. Add Hot Shot with every diesel refill and adjust Pedal Monster to city level 5. Equip a transmission bypass block from PPE, and you're good to go. Rege will decrease to 250-350 every diesel refills. I've also integrated VSE's oil catch. With these tweaks, the vehicle runs smoothly, achieving 38 mpg at 25-mile speed setting, 34.7 at 50, and 27.9 at 450 miles. These minor enhancements ensure optimal performance.
stock I had 400-450 miles in between regens and with the few parts I added, I had 400-450 mile regens. Recently the regens started coming along at 100- 200 mile intervals. I'm currently at 200-300 mile intervals. I believe my dash numbers may actually be above yours, I know at least the 450 one is. But those dash numbers realistically mean nothing. Fuel mileage is what one actually gets hand calculating at the end of the tank, thats 22-23 for me in the ZR2. You have a great setup, it's working well !
I only ever saw 1 regen around the 300+ mile mark, that was when i first installed the I dash. i think timing was coincidental that after install regen distance went down to the mid 1's to mid 2's. Not a big difference from winter to summer diesel that i saw. What seems weird is that driving around in-town seems to load the DPF slower than highway.
I have owned my Sierra for four months. it did regens every few hundred miles for the first couple of months. It now does them about every 150 miles or less. It runs great and , no fooling , I have seen 35.3 mpg on occasion , but it's normaly around 24-26 mpg. Smells awful inside the cab when it does a regen .
Mine has average regen every 150 miles since I purchased it on July 4th 2023 just figured it was because of the much smaller filter also on my second L5P and it still averages 400 miles
i have a 2023 1500 silverado with 33000 miles 3.0 mine just started using def wonder if GM did a over the air upgrade
In my case, they did not. In video #2 I discussed that and verified my programming. th-cam.com/video/wX0xr7Ud_Lc/w-d-xo.html
I just passed 12k miles with my '23 LZ0 I picked up last fall, I have noticed increased oil consumption and regens as well. I do have iDash with logging, I should log my next trip, but it is pretty disappointing and the oil temps really do concern me as well. Getting 238º - 241º F on the interstate and not towing.
Oil temps are fine, these are designed for fuel economy and low emissions, they need higher temps. We have seen no signs of oil breaking down due to the heat, keep it clean and fresh and the temps are a non-issue. Even towing, they stay in check .
My 2023 Silverado 1500 LZO gets me lately 40 MPG less the 65 MPH highway driving but if I go 70 or more MPH I’ll get 27 MPG and I have over 10K miles on it so I notice the more mileage I’m putting in this truck the better MPG I get
Agree with this, have a 2023 Trailboss LT with the LZO at 20k miles on it now. Same happened for me.
Is anyone else having an issue where some of the Regen PID's on their iDash randomly drop off line (no data, just dashed lines). Every so often, maybe 4 or 5 times in the last 5k miles, DPF RG%, DPF SL%, and DPFDIS will stop being reported. Driving a bit more or restarting the engine brings them back online. One time that it happened, I also got a CEL (P2297).
To add to the regen conversation, I've been averaging 160 miles between regens. This was almost entirely short distance city driving (23 - 24 mpg). Recently, I did back to back 700 mile highway runs at 65 - 75, with 29 - 30 mpg and 290 miles between regens.
24 GMC AT4 LZ0 getting regens between 175 -220 miles. All stock with idash.
Is the DEF comsumption relativley the same as your past 3.0's?
no, the LZ0 engines have been more. my lm2's were about .75 gallons per 1000 miles. The 23 was about 1.25 I believe (i would have to check my notes) and this 24 is 1.5+ per 1000 miles.
What i found out with my lzo is that everytime i added anything aftermarket like intake or resonator delete ex, it would regen quite frequently, and fuel mileage would drop significantly. These trucks don’t like aftermarket crap. Put everything back to stock and everything fixed itself. But regens were still too frequent for my liking, i switched to amsoil and now my regens are like you said about every 350-400 miles, my lasts regen happened yesterday according to banks idash it was 345 miles. Im telling you try amsoil you'll be very surprised with outcome
This being my 5th 3.0 duramax, 2nd LZ0, I am not on board with the "mods" since my numbers on both trucks with the same mods showing 400+ mile regens. I know amsoil is a good oil, but the list of things that people say it does is incredible. Longer oil change intervals, quieter engine, better mpg, fixes oil consumption and longer regen intervals. I have run amsoil, it's a good oil, it's just not all that. I appreciate the comment, I do not think the change in regens is due to engine oil, however.
@DemonWorks I didn't think intake pipe could destroy my fuel mileage but it did. I've ran acdelco oil Mobil 1 and amsoil on my lz0 and amsoil doubles in regen cycles
Incredible how frequent regens are with the LZO. My 2023 Ram ecodiesel regen is @900-1000 miles per idash.
24 custom TB LZ0. Just under 1000 miles not getting any notification of regen this normal? Love the way it runs no complaints so far pulls my camper great and millage is good so far.
That is completely normal for a stock truck, I only know when my regen is activated because of my gauges. Stock, you shouldn’t get any notification unless there is an issue. Check out this video for more details

I'm having the same issue. 24 AT4 with 3600 miles on it. Dealer said its regened 19 times. Mine threw code P2463 twice, wont burn off the soot and went into reduced power mode. Dealer said reflashed ECM and replaced an exhaust clamp. We will see...
24' ZR2 here, hardly no regens. @2k miles now and over a half tank of DEF (have not refilled since delivery). I only use renewable diesel so maybe that has something to do with it...
you know anything about why apple car play wont connect? My phone connects to truck but wont play apple car play and i have both car play enabled on phone and truck still wont do it unless its plugged in through cable. i have the newest iphone 15 pro max. was curious if you heard anything on that front.
I have not dealt with that, I am assuming it's a setting issue. Either the phone or the truck.
24 lz0 1800 miles regens starting to happen about every 100 miles. Question, i start my truck and my banks reads my def soot % for about a min then it goes away till i turn off the truck and start it again. Iv got the banks on the setting you said (duramax lm2) iv tried other ones, and the soot % will show and stay on but things like the egt or something wont. Please help
Only thing I can suggest is to switch to the first 3.0 lm2 option instead of the second. You lose some trans stuff by doing that. Maybe you already tried that and that’s where you lost egt? That’s what I tell people with this issue, it’s a 23+ issue and seems to be 10% of the trucks get this problem.
Checks out Lmao sounds like my luck. Also do you know anyway of correcting the spedo for larger tires? Thanks for quick response and the awesome videos !!!
I have all the same exact issues and I’m running banks 1.27.11 beta for the 2024 LZ0
@@robertvocaturo5285 try what I suggested and let me know if it helps
This is why I love my deleted LML…
Thank you for owning the LML, I love replacing the full fuel systems on those after they explode.
@@DemonWorks- 160k and change fuel filter every 7500 miles. Been the most reliable 1 ton diesel we have ever owned.
@@animalbarriegreat to hear!
How do you reset the injectors? I have a 2021 that regens about every half tank.
Dealership can, but I show in the video that it did nothing for my regens. Regen frquency comes down a lot to driving habits. I was alarmed to my only because my regen frequency suddenly changed.
Very normal for LM2s. I'm about 80/20 highway/city averaging ~25MPG in my RST Z71 and will more often than not see two regens per tank or roughly every 250-260 miles.
I'm interested in this truck but new to diesel. what's regen? is it inconvenient?
You pretty much should be unaware of a regen if it takes place while driving on a highway. Here’s a video to help show it in better detail. This Is REGEN - 3.0 Duramax Diesel
th-cam.com/video/DVIgc_7e6BM/w-d-xo.html
@demonworks have you seen code p2c7a pop up and then go away on its own? popped up when i started my '21 lm2 yesterday. went away today after driving 30 minutes. code shows emission issue
Yes, that is the most common code to pop up.
Had it on my LM2 a few months ago. "NOx efficiency below threshold" or something to that effect. My DEF injector was sooted up and spraying an inconsistent pattern. Dealer tech cleaned and tested it and said it'd likely be fine, but they replaced it under warranty because.. why not. Took like 15 minutes to replace after waiting 3 hours for the new injector to show up. Could be same issue on yours, just have your dealer look at it.
I gotta get that I dash so I can see how often I regen I have no clue 🕵️
My 24 L5P is usually around 400-448 thats not great to me either.
Does GM offer any guidance on regen frequency?
no, technically nothing is wrong, there is a code that could show up for too frequent regens and that will come up if the frequency is excessive.
question, how it soot level in DPF measured? By back pressure? or what?
We gotta know how it’s measure before we can find the issue to this, it also could be software issue and an update could simply fix it.
check out the prior videos for a ton of info about software updates and whats been looked at.
@@Miguel-fh7bv I believe there are sensors before and after the DPF and the pressure differential across them is how soot load is calculated.
I think it points to low quality fuel. My regen frequency went down when i changed to a high volume truck stop for my fuel. Also running fuel additive seemed to help as well EDT is my choice due to availability.
I can believe that, in fact, I typically always buy fuel from one station. That same station was where I got fuel from when I had my 400 mile regens... maybe something changed there or their supplier. I will go somewhere else for the next few tanks and see what happens. Thanks for the input !
@Demonworks
Also another consideration is winter Blend to summer blend diesel fuels. Suppliers/ refineries will stop adding certain additives in late spring. Also depends on what area you live in. Just something to think about. Keep the videos coming really like your content.
@@israelmoore495 correct, that’s one thing I brought up in video number 2. However, I’ve had a lot of these trucks and never a noticeable difference from winterized to #2. I’m leaning more towards fuel quality with that switchover.
My 2024 is regening about every 175 miles I don’t know why?
Based on many peoples replies to prior videos, this seems to be the norm for many.
Does delete kit for 3.0 duramax exists ?
I haven't looked.
How much Def fluid are you using???? Don’t the regens use the def fluid, asking for a friend 🤷♂️🤦♂️😂🏁
I have noticed that when I am in “trailer” mode and/or have my engine braking turned on, that I go through more def fluid. The weird thing is… I have never noticed a difference driving my truck, meaning, when it’s in regen. Hell, I don’t even know how to tell it’s happening. I may need to get one of those fancy Banks thingies!
Hey !!!! Towing will use a bunch of DEF, the regens, not so much. DEF consumption is based around engine load, essentially. If you are not rodding, it will use more def, if you are towing it will as well. Just putting around town, it will use less. Each year, gm programs in for greater DEF consumption to meet NOX requirements.
My LM2 would Regen around 225 miles religiously unless I was towing or working it hard, then I could get 400-600 miles between regens. I switched to a L5P and my same exact driving pattern that would yield 225 mile regens in the LM2 actually get me 550-600 miles in the L5P. Same driving pattern but way different Regen distance. Weird. I assumed the bigger engine would Regen more because I'm not working it hard at all yet I Regen way less in it.
I was looking to purchase one but not super knowledgeable about the diesel but the intrigued by fuel mileage
They can be great engines ! The fuel mileage is amazing and the power is great! Take a look around the channel, I share all of my good and bad with each I have had.
Mine started doing that so I put in 8oz of hotshot extreme on a fillup now its back to what it should be.
not the case for me, but glad it worked out for you!
My first 6000km i never put one jug of DEF in, after my first oil change i now have to use a Jug ever 2 tanks of fuel
Yeah, they drink up the def fluid.
If a bunch of yall are seeing this increased regen frequency on your LZ0's, and it's not some phantom OTA reprogramming by GM (@DemonWorks confirmed it's not), then in my mind the only common thing would be fuel. I would not be surprised if the quality of current production is low. The regions have slightly different blends and additive packages for temperature, elevation, etc. I'm in the Chicago area and haven't noticed a difference, but I also have an LM2, not LZ0. Maybe I'm wrong, I don't know, just a guess.
Solid guess, I too believe it was a fuel change of some sort. I do know we went from winterized to #2, maybe this initial batch is "dirty" who knows.
@@DemonWorksI don’t live in Salt Lake City but I travel there pretty frequently to Huntsman’s and fill up before I head back to Nevada. I fill up at Sinclair pretty exclusively and I haven’t had any change in fuel mileage or regen.
@@DemonWorksalso I just had my first oil change done an Ken Garff @ 5,000 miles, no change after the first oil change like others suggested.
That would be very regional, though. A specific refinery could put out some subpar fuel, but not all of them at once.
yes it's the bigger duramax my 2022 6.6l duramax goes 800 miles like clock work before it does a regen 18k miles on it
Two week old 2024 with 1000 miles. Shortest trips have been 10 miles, other trips ranging between 50 and 400 miles. Regen has been every 250 to 300 miles thus far.
Have you reached out to Chevy about this?
No need, it's operating as designed, essentially.
My 23 regens every 130 to 165 miles after my truck passed the 20k miles regentes every 200 to 230 miles … no idea why
I’m thinking it’s all your after market stuff you have put on?
What aftermarket stuff is that?
Maybe an oil change is needed
If you have watched all his other videos, he has pretty much done the same changes to all his 3.0's. And none of them have had this same Regen Issue.
@@DemonWorksThe PPE stuff…duh
Oh, the Charge Air cooler that's been on there for over 6000 miles but my frequent regens started less than 1000 miles ago? Yeah, I guess that could be it. I will ignore the others on here that say they're truck is stock with the same or worse regen frequencies.
MPG doesn't matter when it's guzzling DEF @ $4 per gallon. There is SOMETHING wrong regardless of whether or not you're seeing a CEL. THAT IS excessive consumption. My 2020 goes through about a tank every 5k miles. THAT is "normal".
What’s my def consumption at? I’ve shown in this channel the differences in def consumption over the years of the 3.0, the 2020 ln2 will use the least amount of def. That doesn’t mean each year after is a problem, just means that the emissions requirements go up each year and gm programs them to use more def.
At what point does one decide this is too much DEF usage. 1:1😂😂 somethings not right here.
@@scrooksfulI would say it’s relative to the vehicle. If it’s a vehicle known for consuming, you can’t fault it for doing what it’s supposed to. If you see a sudden change in it, then you know something is up and can look into it.
Regens are more frequent in the passing lane.
Only the second to point it out… I’m surprised. With the b-roll used, I covered up my constant left turns but also explained in a different comment as to why I’m not in the right lane. Funny what people comment about. I really expected more…
@@DemonWorks I didn't read all the comments so I didn't see it. Forgive me.
following....2023 20,000 miles and in the last 2000-3000 miles I am getting a regen every 70-120 miles 😞
Where are you located?
Wonder if it’s pump diesel that has changed and not the truck. This seems to be a widespread issue now
Has anyone check Air to fuel ratios and learning? Poor quality fuel from distributors along with stricter government regulations on emissions could be causing some weird combustion knock and ignition/injector timing being retarded which would result in less fuel combustion and a richer Air to fuel ratio. This could be fouling the DPF faster resulting in increased regens
I agree that it’s likely the pump diesel. I mentioned that in video #2. I’ve also been watching the air fuel with the banks iDash. It’s not as easy to compare like a gas engine would.
When you gonna do a full delete to your 3.0 duramax man?
No plans of that

what are regeneration ?

Maybe the engineers dont show us this stuff for a reason. Yeah my lz0 seems to drink def but at 65mph full of tools im getting 40+mpg.
Get rid of it
I did
They have way to many issues
Mine did
oh, okay.
@@DemonWorks
Not being a jerk , just saying the problems maybe just starting, mine had all sorts of issues starting at 275 miles , and at 36,000 GM finally bought it back, hey run great but when all these problems and there are multiple, it’s definitely not a good vehicle , shouldn’t have any issues for a long time , they cost at least 50k and have all these issues from day one, just not reliable. They should go back to the drawing board or the government needs to get out of manufacturing and let these car manufacturers do what they need to to make a reliable vehicle
Come on look what happened to the gas can!
Just to show how uninformed I am, I had no idea regens occurred so often. I don't own any of these diesels, so I have no experience with them, but I had thought for some reason that when all of this started that one should be able to expect to go thousands of miles (like 5,000 or even 10,000) between regen cycles. Are even the best of tunes this dirty, are these diesel engines absolutely filthy nasty?? For one, I would think that if DPF's become more frequent it might indicate less efficient regen cycles as the DPF ages. I'm not sure how the 3.0 Duramax fuels a regen, but hopefully it's with a 7th injector. Add a DPF and restrict exhaust flow, perform frequent regen cycles regularly requiring additional fuel and you're taking away from the fuel mileage; diesel has already gotten to be expensive compared to the years gone by (ULSD) and you also have the added expense of DEF for operating costs, along with the extra costs of the diesel option up-front. I'm just wondering how long it takes to break even when going with the Duramax over a gas --- and I know that it all depends on what you use the truck for and how often you haul, how heavy you haul, how fast you drive, hwy vs city, etc. etc. etc. This also doesn't count in the 200,000 mile oil pump belt replacement. Please tell me again why I did want a truck with the LZ0?
The new diesel engines are junk with the current emission components on them period..
Not sure I would call them junk but workign around the emissions stuff has created exponential issues, yes.
You are driving in the passing lane slash fast lane the whole video.. 🥴
I was waiting for someone to notice that ! Surprised it took this long to notice. I have my reasons to do it on this exact road. It’s pretty much a death highway with people that come out from the right side at any time, there’s always a terrible accident on this road. I will also add that I made a left turn onto this road in the video and held my line while the guy turning right wanted to go well above the speed limit. Hence, hold my lane …
Regens are lame
Delete it
Valve cover is cracked.and sucking oil in the engine to make it regen more..
That’s a 20/21 issue, thankfully.
New one also are doing it too.
@@Rt-iy5hp That would have to be linked to oil consumption. If the oil level is relatively static yet regens are increasing, it's not the valve cover.
