How’s your LZ0 doing with oil?

@@christianflores6626 great, it used to be a little oil but not bad enough to add any between changes. The truck now has 33k miles on it. Our LM2 has 8000 miles on it. I absolutely love driving both. Oddly enough, I prefer the LM2 because the torque converter engages soon. The LZO slips the torque converter more revving the engine slightly more.

Just did the first oil change on my LM2 2023 Suburban. 1500 miles on it. Usually change the oil on a new engine at 1000 to 1500 miles just for piece of mind. Oil on the dip stick did not appear to move from when I purchased it with 20 miles on it. DEF is still 3/4 full. Was a little nervous purchasing my first GM product from owning Toyotas all my life but so far, the family loved the Suburban. 30mpg highway is pretty amazing as well.

[@SpicerDesignsLLC]

Thats good. Fyi they do add an extra quart in the duramax for the break in. If you look it up you can get a better explanation on why they do it. The LZ0 is a better motor for sure.

@@SpicerDesignsLLC you are correct. I remember checking the dipstick the day I purchased it. The oil read slightly above the full mark. Wish I could have waited for the 2025 Suburban and the LZ0.

I had a similar dealership experience with my Tacoma 4x4. It had vibration at certain speed. Dealer said, they all do that. Well, I found a TSB from Toyota that says if customer is experiencing vibration in front differential at this speed, there is a worn bushing in drivers side axle shaft. Once I showed them that, it was repaired under warranty. Thank goodness for the Internet. Thanks for the vids, even truck ones. Randy

[@martinnorbeck4657]

On the flip side. Warehouse managers jeep grand cherokee kept throwing all kinds of codes after stalling in traffic. He took it to Elk Grove Dodge and Jeep twice. It died the first time ten minutes after he got it back. I looked on internet and found several videos on a common ecm connectivity issue. He took it back to Elk Grove Jeep and told them what to fix. The service guy said they had to send it out to get the crap connections re-soldered. He had already shot the parts cannon at the POS. Never went back to Elk Grove Jeep again. Yes the internet has reshaped repair procedures.

What speed and model year? Mine is a 17 OR with 150k miles. I'm just now getting a vibration at 18-30/40 mph. Thought maybe torque converter. Took it into dealer 4 days ago and they said I need an entirely new transmission. 😑

Good video information! I’m a diesel mechanic myself and work on big rigs. Burning oil is bad but it’s even worse when you have emissions on diesels. Oil does not burn out of dpfs through a regen.

Thank you. Nothing too crazy but i like it. Looks beefy

[@3.0dmax]

Honestly, I was expecting something worse. Kudos to Tim. Every dealership should have a service manager like him. Sadly that's not the case. I would be interested in a post-fix video with oil and DEF consumption report after some towing if you get the chance. I would also accept "It's fixed.. moving on" 🤣 My truck is a bit newer comparing to your VIN. Mine was built in July 2020. I haven't looked, but I don't doubt my valve cover is in the "bad" range too. But I also don't have the oil consumption nor have I had any glow plug issues. In fact I've never had a code come up. So there would be zero chance of having mine replaced. Because it's not "bad" until all conditions are met. I actually read that TSB a number of months ago. Consider yourself lucky that you had the bad #2 glow plug with a code set. Without it, you'd get the typical runaround of the oil consumption being "within normal spec". I mean I can understand why. A typical dealer doesn't want to spend the time to diag and pull out the parts cannon. GM simply doesn't allow/pay for it, especially for warranty work. Ironically I went through exactly this same scenario with my old 5.3 Silverado that was consuming oil because of a bad valve cover. Some things never change.

[@SpicerDesignsLLC]

Thanks for sharing. I will definitely have an update with a final answer on the oil and def consumption. Ill be doing some towing in the next month or two.

[@3.0dmax]

@@SpicerDesignsLLC FYI, I got a letter in the mail the other day from GM. It says my 2020 3.0 "may have a condition that could cause the engine's cylinder 2 glow plug to fail... MIL will illuminate" and to not take it into the dealer for this issue unless this DTC is set. The letter says they're covering this issue 15 years from purchase date or 150k miles. They also included a reimbursement form stating that if you've paid out of pocket for this issue before receiving the notice, they'll cover all costs even if it was out of warranty. I almost have to wonder if Tim and others got this high enough up the GM chain. Something tells me the timing isn't a coincidence. Kudos again to Tim. And also GM for doing the right thing. And thank you so much for going through the details in this video. If mine eventually has this problem, I'm going to request they replace all of the glow plugs even if I have to pay for them, since as they found on yours it was more than just the #2.

I bought 40 acres last fall 1.5 hrs away from home and go there every weekend to work on the property. I also put 100 miles a day on my truck go to work and back. I have 74k on it now and have loved it. It tows my 6000 lb trailer fine and also my 6 seater SXS. A month ago I was 2 miles from home it went into reduced engine power and the code was the one you mentioned. After pulling the code I realized it was oil related. I pulled the dipstick and no oil was visible. I went to Autozone and got 2 quarts of oil and put it in. No oil was still visible. I was now very concerned of a major issue. Went and got 2 more quarts and finally it was in the hash marks. I was close to an oil change and was making a 3hr trip north with the camper so I went an got an oil change. I verified that the oil was full the next morning and it was slightly over the hash marks 👍. Made the trip and no issues and the following weekend I was going to my property with the SXS and decided to check the pil before the trip. It was in the lower ¼ hash marks on the dipstick 😢. I went up north and check oil the next morning and it was under the hash marks 😡. I searched oil google and come across this video!! Called the dealer and explained this issues and the series of events above. Give the dealer the APB number along with pictures from the scanner and dipstick etc. Today I took it in at 8am and they just called me and said this was exactly my issue and a 14hr repair in now in process's once they get the parts!

I’m guessing towing exaggerates it. I’ve towed our horse trailer but that’s only about 7000 pounds. And only 50-60 miles at a shot. I’m amazed it can hold that oil in there. It’s wicked thin stuff. I changed from the genuine oil to the ESP X2 the last service. It was just a little easier to get. As I side note we’ve got an Equinox with the Turin Vaxhaul 1.6. We’ve had decent service out of that too. I’ve had diesels for many years. I work on them for a living so I’m just used to being around them. Tier 4 has been a challenge but it’s pretty much old news now. Keep up the good work!

[@SpicerDesignsLLC]

I can say i will be going back to the 6.6 duramax. I dont have a lot of faith in the 3.0. Thats just my opinion.

[@romadzero]

Tim, just wanted to say thank you. I'm getting scheduled now for my issue. Note my issue came up due to REGEN every 299 miles and one bad glow plug number 3.

[@chaimgreenbaum]

Regen every 300 miles is an issue?

[@davidcrews6170]

Did your dealer replace your #3 glow plug? Also, what are they doing about your DPF? Replace it? Or manual regen? I have a similar issue to you, bad cam-shaft cover, #4 glow plug fault, not #2

[@SpicerDesignsLLC]

@davidcrews6170 they ended up changing #2 again with the bulletin and 3 and 5 were bad as well. Im guessing the issue was getting worse and effecting other glow plugs

[@johnfogg7858]

Seriously! It doesn't matter what the subject is, you videos are always enjoyable!

[@SpicerDesignsLLC]

Thanks John! Much appreciated

[@davidbrieske]

Thank you for your videos. I'm looking to replace my Ford F150 with a 2024 GMC Sierra 3.0 Duramax and I was concerned about the Oil Consumption issue. Now I feel at ease with that purchase.

[@SpicerDesignsLLC]

Good luck with your purchase

[@hossein3867]

Thank you for the great information, I don't even own the LM2, but what amazing info for those who do and use excessive oil/DEF. Tim, if you are looking at this video, god bless you.

[@SpicerDesignsLLC]

Thanks for the nice comment. Much appreciated

[@brandonmorrison2379]

I've had this exact problem with my 09 chevy 1500 with 6.0 All I do is tow and it'll go through a quart every fuel fill up. I've spent 10 grand, months of sticking it at multiple mechanics. Every single seal in that engine has been replaced. Turns out i should've just researched it myself because it's only a defective valve cover that I can replace myself along with tuning out AFM. Still tempted to ditch the truck after all that.

[@SpicerDesignsLLC]

Ya i dont blame you. Ive never heard of a 6.0 in a 1500. Is it a 2500?

[@brandonmorrison2379]

@SpicerDesignsLLC nope it's a 1500, super rare.

[@SpicerDesignsLLC]

@@brandonmorrison2379 ahh is that one of the HD’s. My buddy used to have one of them.

[@douglasburchat3304]

Hello , I would recommend starting a file with gm customer service, the issues you have may resurfaces latter in the vehicles life , your scr and egr ( exhaust particulate filter )plugging and needing replacement wouldn't be uncommon. Somthing to monitor going forward.

[@delriv5238]

I’m burning oil on my 2021. Thank you for the video

[@Matt-zn4zp]

Thanks for sharing and big thanks to Tim for helping all of us out!!!!

[@steve9395]

Thanks!

[@SpicerDesignsLLC]

@@steve9395 thanks Steve!

[@patrickc8190]

Thanks for this, I have heard of this issue, I have a 2022 with a 3.0L diesel with no issues , but i'm sure there are some who do and can't get any satisfaction from their dealer.

[@danielrobert7181]

Great video and a special salute to that absolutely charming lady we saw too little of !

[@SpicerDesignsLLC]

Thank you. She should be in the next couple videos. Shes always busy with the kids.

[@MixedGrid]

Great video. Glad the word is getting out to help others owners of these amazing engines. 💪😎

[@joewhitney4097]

Very interesting, kudo's to Tim and his team for helping get to the bottom of your problem. Thanks for sharing.

[@davidbruce5377]

I have a 2024 3.0 and burn oil like crazy. Crickets at the dealer. I wonder if they haven't fixed the issue. I didn't see 2024 on the service bulletin. You just have a new subscriber!

[@SpicerDesignsLLC]

@@davidbruce5377 well that sucks to hear. I can say that i will not go back to the 3.0. I do have an update coming soon.

[@bryandavies9212]

Great video and sounds like Tim actually cares. Thanks for sharing!

[@jenniferlyn281]

Thank you so much for this video! I have had all kinds of problems with my 2021 Silverado with the LM2 engine. I shared this video with the techs at my dealership and they are going to replace the cam shaft cover on my truck.

[@SpicerDesignsLLC]

No problem. Glad to hear they are going to take care of it for you.

[@scarface-39]

Are they going to do it under warranty?

[@dadgarage7966]

Tim was just doing his job. Tim shines because so many people in the auto repair field are abjectly incompetent.

[@SpicerDesignsLLC]

I agree….but Tim did go above and beyond to help me out. Too notch

[@jimwilson9005]

Thank you the information in this broadcast was great community benefit unfortunately manufacturers don't always go the extra mile and that's service writer that helped you he is a Prince

[@Tim4111]

Service manager...I'm too old to turn wrenches anymore ...and I leave Service writing to the kids 😅

[@IndyFarmLife]

"Tim for the Win" that's a t-shirt right there!

[@dtay8697]

Had the same problem, didn't need to tow anything to burn the oil. 2 qts every 1000 miles like clockwork. Needless to say I will not be going back to the same dealership again. They had taken the engine apart over a dozen times to fix it, then it was a constant oil leaking machine.

[@patrickyoung5348]

Thanks for sharing this. I have a 2020. I’m not experiencing these problems but it’s great information to have incase I do later.

[@jasonglaser7114]

Had the same issue on my LM2 towing my trailer this 4th of July. Eating through DEF and had basically no oil when I got home.

[@SpicerDesignsLLC]

@@jasonglaser7114 were you able to get it fixed. I still want to get rid of mine even after its fixed. Now i smell oil in the cab all the time. No idea what that is.

[@dmiller5164]

Sorry I'm late to this thread but it just popped up for me.... Very cool to share your experience and solution! Could you share your after resolution oil consumption and DEF usage, towing and not towing?... Thanks

[@SpicerDesignsLLC]

I have an update coming soon. I shot the video just have to edit it. No towing info though

[@joemurray9131]

That is awesome that your truck is fixed

[@SpicerDesignsLLC]

Ya im pretty pumped about it

[@colton7846]

Mine used to consume oil when I ran ACDELCO. Switched to Mobil 1 and it stopped completely. No idea if that was a coincidence or not.

[@johnwinter9722]

Good outcome! My third 5.3 is great. But there are incentives on the ‘24 Babymax right now. Hmmm. Thanks. Confidence in the Bowtie restored.

[@kevinvoyer5053]

Yea TIM! let’s all put him in for regional service manager! But what a great video! Now my questions, what normal commuting mileage do you see, highway mileage you see and towing mileage? Plus what does the lifetime mileage average on the driver information center say?

[@williampiepmeier4301]

Spencer, reached out in response to my comment from the hate video. If you had led with the problems and wasn't such a hater of the 3.0. Very offensive. I appreciate the info provided by you about the tsb. You know as well as I do that a dealer will never never reach out. Good job in sharing. I love my 3.0 and the only thing I would do with mine is buy the 2024. If I have offended you in any way, I apologize for my comment. Best of luck with your 2020.

[@SpicerDesignsLLC]

I appreciate that. Not offended. Ive received a lot of backlash from that original video but it led to the repair which ended up helping a lot of people. Some that didnt know they had an issue. My addressing issues with a vehicle should never be takin personally. No reason for it to be offensive.
