What's The Difference? NEW LZ0 Duramax Engine Replaces LM2

[@robs85gmc]

This new LZ0 is incredible, I routinely get 30+ mpg on trips around town. It was this channel that helped me realize that the 23 model year got the new engine. Thanks!!

[@johnadcock6852]

I haven't seen that level of economy in a RWD model. More like 26 at best on the highway, 23 - 24 in town. Are your results from babying it on the highway? What are you getting in town?

[@robs85gmc]

@@johnadcock6852 I don’t really worry about fuel economy but my best reported economy was 34.3 and I was averaging 70 on the freeway mostly because of traffic. If I just drive normally not too aggressive I usually see 27-29 on trips around town. If it’s a very short trip with lots of stop and go it might only be 11-15. My other truck is pushing 700hp so I am pretty gentle on the throttle with this one, all the torque is down low anyway.

[@slickcasner4205]

I have a 23 GMC 3.0 with max tow. It has 3.73 gears, bigger radiator and alternator. With the 3.73 gears and A10 combo it’s a beast. The 15’ GMC 6.2 had to run the RPMs up and struggled a bit pulling my inclosed trailer up the hill by my house. The LZ0 with max tow does not struggle at all.

[@brandedmcgowan9414]

GM unfortunately doesn't put aggressive gearing in the 6.2 V8 to give it the low end grunt it needed, I believe the 3.42 is the max gear they put in with the 6.2, a 3.73 is needed for that engine in order to get the job done, good thing RAM gets the 3.92 gearing with the 5.7 HEMI that can pull like a semi.

[@Slane583]

I looked at a newer Silverado with the 3.0 Duramax back in August as a replacement for my 2020 Silverado when its' original lease was up. But the only one our local dealer had on the lot was going for $80K which was way out of my budget. So we decided to just continue paying on my 2020 Silverado with the Turbo-4 in it. I like how it drives and it's done what we want without issues. When we have it loaded down with soggy decaying wood chips in the summer it doesn't even feel like there's anything in the bed. Since the 3.0 Duramax uses the same wimpy PF66 oil filter as my Turbo-4 I bought the upgraded PPE filter for it and some AMOSOIL Signature a few days ago to do an early oil change for the winter. I just need the time to get around to it before the weather gets too bad. :)

[@Sparktrician]

Looking at buying a new truck. I found your channel because I’m considering ordering an LZO. Also considering a 6.2 and a 3.5 Ecoboost. Currently I have a 2019 3.5 Ecoboost and it’s been a good truck. However all of the issues you hear about Fords warranty issues I’m exploring my options. I like what I hear about the new LZO except for one thing. Oil consumption. My question is are these really the oil burners I’ve read about? I also read under normal conditions GM considers 1 quart every 2k miles as normal. Tow with it and it’s consumption doubles. Have you seen this? Obviously your an LZO guy but I also read a lot of ugly things about 6.2 failures and AFM. Just looking for your input on the oil consumption. Other than this it looks like the 3.0 may be the best engine GM is offering in their 1500’s. Thanks for the videos. Look forward to your thoughts.

[@DemonWorks]

Hey, welcome to the channel ! I love my LZ0, I did have 3 LM2's prior and the only reason for replacing those was taking advantage of the market and upgrading each time.... My LZ0 did experience oil consumption in the first 3000 miles but the next 2700 have shown a half quart consumption so it's all good ! The 6.2 is an amazing engine and if I didn't get this 3.0, I would be in a 6.2 for sure ! Yes, they have lifter issues, potentially. I am a GM tech so I see that and to be honest it's not every single 6.2 will have the issue... some do, many don't but we just hear about the problems, not the good ones. You won't be disappointed in either choice, report back when you do get something and/or if you have any more questions.

[@ricksmith4736]

I have a 20 Silverado I purchased new that has 15K miles on it... OIl changes at 1200, 5k, 10K and 15k... Absolutely NO oil use..... I love this truck but the best thing about it is the 3.0 liter Diesel in it... It is such a joy to drive without revving the heck out of it.... I just kinda cruise wherever I go... Best decision I made when buying my 2020 Silverado.....

[@Brandon_Nelson92]

I've had 4 diesel trucks and also currently own a 2019 3.5 ecoboost f150. One of the guys I work with just bought an LZ0 duramax and I was impressed with it. It is almost as satisfying as the 3.5 ecoboost to drive. He's getting 26mpg. I get 20mpg. Both engines are excellent at towing. The 2nd gen 3.5 ecoboost has cam phaser issues. Ford's most recent update to the phaser design finally fixed the issue. If you have cam phasers from before January 2022, there's a good chance they'll go bad before you hit 150k miles. Mine will likely need phasers out of warranty and I've already accepted it and will address it when/if needed. Other than that, the 2nd gen 3.5 has proven to be a solid engine. They make huge power with tuning and have no emissions BS to worry about. The 3.5 didn't even have EGR until the 2021 model year. I'm not selling or trading in my f150 any time soon. If I had to replace my truck, I'd be looking for another 3.5 ecoboost f150 or an LZ0 duramax. It would boil down to which one I could get a better deal on.

[@jasons5842]

GM raised the oil pump belt replacement interval because it doesn't matter if it's 150k or 200k it isn't under warranty so they just want you to not worry about it. Remember the Jedi mind trick? "These are not the droids you're looking for"

Can anyone give examples of their payload rating on this configuration? We all know by now how shady ALL the truck manufacturers are when it comes to payload, it's infuriating. It's impossible to find any real info without actually looking at door jam stickers. Unfortunately, there are no RST double cab LZ0 trucks in inventory near me that I can go look at.

[@chadmark88]

Great video . . I'm glad all those changes took place. I have a question for you about the regeneration system on the 3.0 Duramax engines . . . I drove a new diesel school bus ( 17 years ago now ) which had obviously a different diesel engine, but the "regen" system would come on at least once a day, sometimes twice !!! When it was on, we were told NOT to turn the engine off - driving down the road was fine. Many times for me, it would be on when I got back to the lot and wanted to turn it off !!! Do these new diesel engines have a different way of doing the regen cycle ? MAINLY, not as often as back when I drove one ? I'm thinking about buying a new Yukon diesel, but I do mostly short trips around town - five miles or less - and I'm concerned about getting to the store or in the parking garage at the doctors office I go to monthly and having to wait until it stops "regenning". You said the Yukons don't have the LZ0 engines yet, but I might order a 2024, which could have it - either engine will still have to do the regeneration, anyway.

[@k3iler05]

Hey. I am a truck driver, so I am familiar with newer diesels. I drive a 2023 Cascadia. I am sure the 3.0 works similar or even better, since all new technologies are tested on pickups, before they work themselves to the big boys. Diesels don't like short trips, or idling very much, but you should be fine. Even if you get home or to the store and it needs to regen, it should not take that long to complete the process. It is not as cumbersome as previous engines. The technology has gotten a lot better. I would really like to get a 2024 Yukon XL Denali. Let's see if I can get approved lol. Cheers.

[@Hacksaw2055]

On another video by another KZbin author he highlighted that at or 100K mikes the transmission would have to be removed to check a belt that is on the back of the engine. He also denoted that the 3.0 had concerns with the rear main seal was reported to be a constant leaking problem. Also he said the engine was having reported long cranking times to start the engine. I value your topic in this video identifying the new pistons. BHH

[@DemonWorks]

There’s no checking the belt, it’s 150k, you replace it and yes the transmission is removed or pulled back for that. The 23 trucks go to 200k for that. The rear main issue was a small number of vehicles and was a casting issue. Seems to be resolved now. The crank no start is a programming/reluctor issue and has been resolved for 99% of the trucks with just a reflash.

Can you actually feel a difference with the extra power? I've talked to a couple people that have bought them and they told me they don't really feel a difference from the lm2.

[@codered9576]

I heard the same thing also. When you're that high up in numbers an extra 28 HP and 35 pounds of torque isn't really going to be noticeable at all, maybe if you're towing at full capacity but as a daily driver you're not going to really notice anything. They changed a few parts to different materials but basically the engine is the same,I think it's more of a selling point.

[@Jay-me7gw]

Probably because, when you have 460 ft-lbs @ 1500 rpm, your don't really get into the rpm region where the extra torque helps out in normal driving. They are only adding 35 ft-lbs and its slowly ramped in from 1500 rpm to 2750 rpm. So unless you are closer to 2750 rpm a lot, you simply wont feel a difference, and even then its not huge. At 2250 rpm theres only going to be maybe a 20 ft-lb difference which you would barely feel. Where I bet you feel it is with a trailer hooked up pulling a grade. And the difference will grow the higher you are above 2750 rpm where the torque curve was stretched to make the extra 28 hp.

[@jnk26]

Hp is a result of more torque at a higher rpm. If you have 1000lbft@1313rpm is 250hp 1000lbft@2626rpm is 500hp 1000lbft@3939rpm is 750hp 1000lbft@5252rpm is 1000hp. It's just an equation for the amount of work done in a given time. 1000lbft is a 1000lbft. Doing the same amount of work 4 times faster 1313rpm vs 5252rpm. Same could be said for a 250hp@5252rpm engine. It would do a 250lbft load at 4 times the speed as the 1000lbft motor at 1313rpm. In the end the same mount of work gets done in the same time frame. The 3.5EB with 375hp@5000rpm(393lbft) is the same strength as the GM 6.2 with 420hp@5600(393lbft). Torque is what does the work(force) hp is how fast that amount t of work gets done.

It's 9.5 hours labor for 4wd, 7.5 for 2wd. About $350 list price for parts. @$225 Hr labor rate, it should be about $2600ish for 4wd and $2200 for 2wd.

Why would they not change the oil pump drive belt lifespan on both engines if the P/N is the same especially since the oil pump output pressures are lower on the LM2?

[@DemonWorks]

Likely because the prior engine already was already done and they would have to redo owners manuals and what not. Extra effort…

[@kaivonmortazavi8656]

Most likely its due to changes to engine cooling. From my manufacturing past, if its the same P/N then it has to be exactly the same part. Most likly the LM2 has a longer life cycle than advertised but GM is probably hedging their bets with this first generation 3.0 LM2.

[@kaivonmortazavi8656]

Thank you for another educational video - learning a lot. I was wandering if you could elaborate on the increased DEF consumption. You went from X gallons per X miles on your LM2 to what gallons on the same number of miles. Can you give an indication on increased consumption? I have an 03 Tahoe on order but have been on the fence about cancelling and waiting for the 04 in hopes that they will offer the LZO then. Not sure if the changes are significant enough or worth it to wait and most likely end up paying an extra few thousand on the 24 model or if I will even like the refreshed…..Just cant decide.

[@Jay-me7gw]

My understanding was that the 2023 LM2 in the SUV's does get an increase to the 200k interval. Whether or not they will retroactively increase the 2019-2022 truck is another story.

[@DemonWorks]

@@Jay-me7gw correct for the 23 lm2, I don’t see it being retroactive. Not that it matters though, as none will be in warranty so the owner can make the decision to drive longer if they wanted.

Honestly this GM Diesel has me contemplating switching from my Ford with the 2.7 ecoboost. I’ve always been a fan of diesels and this one knocks it out of the park..

[@DemonWorks]

It absolutely does! When you make the switch, I’d like to hear your perspective going from the 2.7 to the 3.0 diesel. Yes, I said when you make the switch 😉 😆

[@jetdust]

@@DemonWorks just not sure if I want to increase my current payment otherwise I’d be on it!!

[@scottandrews4822]

Have you heard about the GM APPTOVED use of HIGH OIL CONSUMPTION in the LMO ? What's going on, GM? Can't you build an engine that doesn't use oil?

[@DemonWorks]

Gm has always had that number for oil consumption, in all of the engines. Under normal use, you shouldn’t use very much at all. Under high rpm and towing, it will use some oil and that’s where the numbers really come into play.

I don't know I have had multiple GMs go forever. I have a buddy with a 3.5 ecoboost that is at 140k miles and his 3rd engine already. I just sold a car to somebody recently had had to buy a new short block from Ford for his 3.5 too within months of the warranty expiring. Then you have that garbage 5.4 they made and the transmissions behind them and the Rams blowing head gaskets and oil pumps and electrical issues.

[@ktpinnacle]

I assume that this LZ0 still will not fit in the modified engine bay of the AT4 and Z71 SUVs.

[@Jpmpmpm]

Lz0 escalade yukon all of them i want please more easy to afford in europe countrys

[@dcman4902]

They forgot to make the oil pump belt a chain instead of a belt 🧐. They say it should last till 200k miles, though when you have to service it the only way too is pull the transmission…. Good engine other than that issue that will be an issue when they get older.
