I Review the 2023 3.0L Duramax Diesel LZ0 Engine in a 2023 Chevy/GMC 1500 truck. I go over the pros and cons of this diesel engine, MPG, Horse power and upgrades as a heavy duty diesel mechanic and give you guy my opinion whether or not this 3L inline 6 Duramax diesel is a good engine.

This is the second gen 3L duramax in these chevy 1500 pick up trucks and I really like these duramax diesel engines. they are incredibly fuel efficient and can now tow up 13,300lbs.
I like that these engines are inline 6 designs because of the 3 main advantages including being naturally very well balanced engines, easy torque creation and great engine bay layouts.
I also really like that the emission systems on these 3L duramax diesel engines are not showing many issues which is a huge bonus seeing that emission usually kills the modern diesel engine.
some of the upgrades of this second gen duramax diesel engine include, new steel pistons, stronger connecting rods and thicker cylinder wall linings. this new engine also has an updated turbo, new cylinder head, new intake cam and intake valves as well as new fuel injectors.
all these upgrades really help to open up this engine and let it make more power.
some issues to look out for include the oil pump belt and fuel pump simply because of their location making it difficult to replaced them.
there is also some rumors of oil consumption with these engines but it is also very early on and tough to conclusively say if this is an issues or not.
overall I really like these little 3L Duramax and thing GM has a good product on their hands.

I've had just about every brand of truck and I can honestly say this is the best I've ever seen , updated interior is amazing, AT4 options are great , I traded in my 2021 6.2 AT4 due to terrible gas mileage, was fun to drive though ! I'm more then happy with my decision to go diesel so far.

Thanks for making this video Alex. Alot of good info. on a vehicle I'm considering. All of the items you described as internal engine improvements such as the connecting rods, pistons, and wall thickness, indicate that GM is looking at much higher outputs for this engine. If anyone else knows of reliability issues with these engines please let me know. Until you mentioned it, I hadn't heard about the oil pump belt replacement access issue. Thanks for that.

Just bought one at the end of July, and absolutely love it. Took a trip from Victorville CA to Las Vegas, and averaged 36.2mpg. Granted, I do drive with a soft foot. But still amazing mileage nonetheless. Now a little over 2K miles, I still enjoy driving it, like the first day I bought the Truck. Around town I am still averaging over 24mpg, and over this period of time, I’ve topped off my DEF, only using 1 gallon. As far as oil consumption, I havent experienced any issues at all. At 1K miles I did change the oil (definitely early, but I am very compulsive with my maintaining the vehicles I own). So far this truck has been everything I had hoped it would be. As mentioned above, I am out of California. So with that, this truck has been drinking nothing but Renewable Diesel since day one (with the exception of a fill while in Vegas). I would recommend this truck for anyone in the market for a 1500 sized vehicle.

Neither the dealership nor GM’s field technicians have been able to identify a permanent fix. So it looks more and more like I just got a lemon. Just threw in the towel and traded it in for a 2024 Duramax this week. So this video is very reassuring.

I have a 23’ GMC LZ0 MaxTow 4x4 crew cab with the 6’7’ bed. Averages between 26 and 32 mpg. Pulling my 22’ enclosed trailer that is a foot taller than standard. And around. 9000lbs. It pulls the hills at 70mph in Kentucky without losing any speed or laboring. My old 15’ GMC V8 would struggle to maintain 45mph. Also, averaged just under 50% better fuel economy than the gas V8 pulling. On the 600 mile round-trip. It did use 2 1/2 gallons of DEF. New truck has just over 6000 miles now. It seems to use last year the more miles I get on it. I have also not noticed any oil consumption. First oil change was 1700 miles second was 5000. Both times was still ride on the full mark.

@karlschauff7989 Ай бұрын

If you notice any oil consumption, there is a TSB for the valve cover and yours may or may not be affected. GM redesigned it to avoid the issue that the supplier had when making it. There was a internal defect in the cover that the supplier didn't notice and it can allow engine oil to leak into a ventilation tube and get pulled into the engine. It causes glow plugs to eventually fail and the DEF/EGR cooler to get clogged if it's bad enough. Hopefully yours doesn't have the original valve cover. It doesn't sound like it but I thought I should mention it.

Bought a new Sierra AT4 in March 2021. The power and fuel mileage is super. That's why we bought the Yukon diesel 2023, this year in July. After driving them both, side by side, there's a noticeable difference. Where the power in the truck comes on immediately, the Yukon is a bit more delayed, but it is much more at home at 85 mph (ya wife has heavy foot), with better fuel mileage. We love them both.

I own a 2023 with the LZ0 and I absolutely love it. I drive a semi daily for work and this LZ0 was a no brainer for me from a design standpoint. The first generation 3.0 LM2 did have an oil consumption issue for some vin #’s that was addressed and fixed through a service bulletin (22-NA-027). Something to do with a camshaft cover and glow plug. This in turn also increased DEF consumption and caused more frequent regen’s. Not a big deal as they got the issue solved and affected trucks fixed assuming owners took them in.

I just put over 19,000 miles on my truck and it seems like this happens every few thousand miles. I haven’t counted, but I’d say it’s happened about 10 times. It will start up after the cold crank, but it still concerns me a little bit.

There is a software update to fix it. The reluctor wheel has a bent tooth due to the supplier's manufacturing method and it can confuse the computer when it goes to learn the angle position at startup. The issue and the software fix was explained in an interview on youtube with the title "Exclusive Interview! Chevy Engineer on 3.0L LZ0 Duramax Diesel Changes".

I had a 2022 LM2 and now I have the 2023 LZ0. Only thing I will say that I think you missed on is DEF consumption. I got 6000 plus miles out of my first tank of DEF on my LM2, this lZ0 doesn't even get half of that, I have to fill it up every 2000-2500 miles now. So she drinks DEF like crazy compared to the Lm2. Also they made some subtle exhaust changes, they added a backpressure valve halfway down the exhaust, which failed on me within the first 1000 miles. It was making a very annoying ringing noise after the exhaust heated up to operating temperature, the dealer had to replace the exhaust from the valve back. Other than that I'm pretty happy with it, no other issues! 7500 miles on it now.

Ford started using oil pump belts on those engines but they're at the front.

I have a '16 LTZ with the 6.2 that I love but am putting a ton of miles on the vehicle on the interstate. The 6.2 is an extremely good motor and I'm still getting 20mpg's average on the interstate if I stay just over 70mph (93octane)... all things considered, that's not too bad especially since I'm on 35's, and a coilover King lift low lift kit. I love the character and power of the 6.2 which is one reason i bought the unit. However, I'm seriously considering trading/retiring my '16 and getting a new LTZ/High Country considering the miles I'm driving. My question is... how vastly different does the 3.0 feel vs the 6.2V8 gasser? I'll be doing the same with the new truck making it an overlander (King coilovers, 35's, low lift kit, camper shell, roof racks, etc.). Cheers! edit: Also, can you tune these 3.0l's to get a little more power/torque? I'm sure these aren't as bulletproof as the 6.6's but there's no harm in asking ;)

@jonremkus1630 3 ай бұрын

@@freidrichnietzsche6643 Yes, lots to love about the 6.2. I just had the dreaded lifter/camshaft/pushrod combo on our 21 Denali. GM came through on a +100k mile component coverage letter, so I am going to drive it until the wheels come off. I have a ZR2 at 37,000 miles and I don’t see myself keeping it beyond the powertrain warranty, even though the gear ratio seems to do even better with the 6.2 than the Denali for how I drive. I had a ‘21 Suburban 3.0 that I traded for the truck because I needed a bed, but I really liked it, so I picked up a Yukon XL with the 3.0 when the Denali went down. I think the 10 speed and the diesel match up so well along the torque curve that there really isn’t a noticeable difference in performance under almost all circumstances. The diesel is just so darn smooth. That said, it will drink DEF when towing moderate to heavy loads - at least my Suburban did, and I’ve heard the new revision is even worse, so that’s worth keeping in mind. Maybe a software revision has or will fix that. I haven’t towed with the Yukon yet. There’s also something to be said about having 600 miles of range on a tank that I really like. All said, I’m a big fan of the little diesel. Good luck to you!

The only big difference I've noticed when trailering heavy loads is a major increase in the amount of DEF it uses.

Like they dont want to make a engine that will do 300k without lots of engine repair expense. You know if they really wanted to they would. Earlier straight 6s and many 4 cyl would do 300k.

I'm enjoying my '23 Silverado RST Z71. I get 15-17 mpg towing a 3500 lb. trailer and recently did a 1900 mile round trip without the trailer and averaged just under 30 mpg. According to the driver info center my best mileage over 50 mi. was 39.6mpg! The engine is also very smooth and quiet for a diesel. A huge upgrade from a 2013 Frontier.

@StephenPaul1160 11 ай бұрын

The emission systems "magic" is that the low pressure EGR is AFTER the DPF. Clean gasses go back to the intake manifold. There is a high pressure EGR coming off the exhaust manifold that is used during warmup, but once up to temp, the engine switches over to the clean low pressure EGR. Also, as you mentioned, the DPF and DOC being so close to the exhaust manifold helps them to get up to temperature quicker and therefore they get more passive regen and active regen is more effective. These two design elements come from many years of SCR diesel engines and looking at what causes emission system issues in them over the life of the engine.

In your next video you should explain the emissions system how it’s different from anything else on the market. Since the DOC catalyst is right after the turbo and sandwich up against the block it’s easier quicker to get hot like you said. But also the EGR on this engine is after your DPF so most of the soot does not go into your engine which keeps things cleaner and imo keep your engine from wearing out prematurely.

@TheGettyAdventures 11 ай бұрын

It's a very interesting system from GM and makes alot of sense. The cummins engines suffer from soot issues but with the EGR gas coming after the dpf the soot is essentially zero. Very cool from GM.

I think I understand the reasoning behind a belt-driven oil pump located at the back of the engine. GM management thought, hey, the EPA is forcing us to make EV's that don't require any service, and the dealers hate us for it. Let's design a truck that will be so expensive to maintain that the dealers will sing our praises. But...how can we do that. I know! We'll let first-year engineering graduates design critical parts of the engine! GENIUS! I wonder how many hours of expensive diesel mechanic labor will be billed to change the oil pump BELT on a 4x4 1/2 ton pickup? More than the truck is worth, of course!

@karlschauff7989 Ай бұрын

It's hilarious seeing people whine about a belt that's good for 200k miles being at the back of then engine, but nobody whines about Ford using the same kind of oil pump belt on the 2.7 Ecoboost and 5.0 Coyote in the F-150. Ford put theirs on the front of the engine and as it turns out, it takes more labor hours to replace that belt because, as it turns out, there's a TON of stuff you have to remove from the front of the engine to remove it, including timing chains. If you think that belt on the Duramax is expensive to service, just wait until you see the bill for replacing that belt on an F-150 2.7EB made in the last few years.

@@David-yy7lb As will every F-150 built in the last few years. Seems like Ford is determined to use rubber bands to turn all their oil pumps, only they're vindictive enough to put that the rubber band BEHIND the timing chain. And it turns out unburned gasoline in the engine oil breaks those belts down way faster than anyone would ever expect. So to change that rubber band on one of the F-150's variety of engines, you're pulling the cooling fans, all the accessories, the harmonic balancer, the timing chain cover, and the timing chain itself just to change the belt at 100k. I say 100k because having seen a ton of these belts at that mileage. I wouldn't wait any longer because all the debris that was coming off those belts was getting sucked into the pickup screen molded into the bottom of the cheap plastic oil pans Ford insists on using.

As mentioned in the video, heating up the emissions components quickly is key to their operating well. GM put the DPF as close as they could to the exhaust ports. This created challenges with managing the heat under the hood, but apparently doing so paid huge dividends in emissions system reliability. The DPF also filters much of the EGR before it goes back into the intake stream, which also helps reliability and cleanliness of the engine. A friend has a Sierra with a 1st gen 3.0, it has 75K miles on it and it has been flawless to date. It also drives really well. Have been in it while towing an enclosed 7x16 trailer loaded with dirt bikes and gear, and it stays in 10th gear on flat ground at 70. It has amazing torque, and it is quick when it is unloaded.

Great Video, just bought my 1st GM Duramax last week. 2024 Elevation, 4x4, Black and loved it from day 1. Until it broke down & left me blocking the car wash after it didn't start/crank. 1 week, 490 miles & broke down. Towed to dealership and had to get a loaner. Starting my new job with need of my truck & it's in shop with BAD ECM. SO DISAPPOINTED and I regret buying it already. Been driving Ram for many years, no issues & decided to try an economical GM because the tow capacity, economy & look. But 490 mile break down & I'm really doubting I'll male it until my loan is paid off without problems.
