Agreed love my 2024 gmc sierra 1500 Denali best truck on the market and good dealers are doing crazy discounts and incentives and interest rates. Saved 15k plus Costco 1k incentive and vet incentive $500 paid with extended warranty and maintenance plan 80k all in.
I've been with GM Fleet and Commercial Sales since 1997. On my 2nd one now. 2023 Crew LZO. Best engine we've produced. I tow my 5,000 bass boat, get 20 mpg and can't even tell it is back there. Way over 30 mpg highway. Never go back to gas!!
Thank you for putting this together! I just bought a 24 AT4 with 3.0 diesel. I love the truck. I watched a bunch of your videos as well as DemonWorks before I made my move. I couldn’t be happier. Thanks for your input and insight. 🙏🏻
@ The truck runs flawlessly. I don’t have a need to tow so it’s just a commuter, with that said, it’s quiet, has a nice ride and gets between. 25-30 mpg regularly. Came from a Tacoma so it’s so much more roomy and plush. A nice ride height allows for great road vision. No regrets so far. Only once flaw I have observed, the backup camera is NOT good at night. Totally useless. I typically get 600+ miles to a tank and it hardly uses DEF.
Just bought a GMC Sierra Denali with the Duramax. First diesel vehicle ever and I’m definitely loving it. Thank you for the video. First 200 mile round trip I got 35 mpg, I was blown away.
Great video Tim. Just a note about fuel economy and DEF usage. I had a ‘23 Sierra 1500 AT4 3.0 Duramax (LZ0). When towing, even a small increase in speed dramatically changes your diesel/DEF consumption. I’m up in Canada and I found the towing sweet spot with that truck / engine was between 100-105 km/h (~63mph). Towing between 3,500 - 5000 lbs at that speed, the mileage/DEF consumption was great. When I set the cruise at 110+km/h (~70+mph) the fuel/DEF consumption was alarming. As you state it absolutely drinks DEF, I actually ran my DEF tank empty once on a trip because I didn’t realize how fast it was hammering through it. That’s just how it is when towing…if you can back off the speed a bit, it makes a huge difference. Otherwise, crack open the wallet and get ready to pay. I had to move on from the ‘23 Sierra, living in Northern Canada(Northwest Territories) with extended periods of extreme cold I had some problems my dealer/GM could not solve with the LZ0. Other than that, that truck engine combo was just excellent. I have ‘24 2500 Sierra AT4X with the 6.6 now and it’s the same story with fuel/DEF usage. Keeping that truck below 70mph makes a huge difference when towing. I just did a 4,500 mile road trip, towing the whole way (4000lb enclosed), and when I cruised under 110km/h (70mph), the truck got great mileage and was easy on DEF. At some points when I just wanted to make some time up, it hammered through DEF and diesel. I knew it and I was ok with it. Enjoy the channel and your videos Tim, keep up the good work. Dave
As I posted elsewhere, DEF usage is essentially correlated to fuel consumption. More fuel consumption = more DEF consumption. Put simply, if you double the fuel consumption of the engine, you will likely double DEF consumption as well.
I have 24’ 2500 sierra at4 dmax have got it down driving on highway to 8.6/100 what I noticed long drives on the highway the truck sips fuel and anything in town I just drinks it lol overall no complaints.
I had a 2020 Silverado 1500 and currently have a 2022 Suburban with the 3.0 LM2 motor. Neither burned a drop of oil in 5,000 mile oil change. Also, the DEF usage was reasonable. This is an awesome motor.
My 2024 hasnt burned any thus far. Most oil consumption issues were with the LM2 due to valve covers having bad internal welds that allowed oil to get sucked into the intake. That also caused many other rumored issues that get spread on the internet. The oil would foul glow plugs and ruin the emissions system. To make things worse, some dealers and guys doing their own oil changes were using Dexos oil for gas engines instead of DexosD oil meant for this engine. The gas engine oils have higher ash content that is terrible for catalyst and filter.
I have a 2020 with the LM2 and have put 92k on it so far. Never seen the inside of a dealership garage. Just oil changes/fuel filter changes. Great engine!
Just turned over 1K miles on my new 24 GMC Denali 3.0. Went on a trip yesterday in the hills and turns of Eastern Ohio and Western PA - Avg'd. 33.2 mpg. First diesel I've had and NO regrets. I know it's new, but from what i'm seeing now, I don't vision going back to gas anytime soon. THANKS Tim, great video!!
Based partly on your videos, we pulled the trigger on this engine in a 2023 Sierra SLT. This 3.0L diesel mated to the 10 speed tranny is a dream to drive. I’ve never noticed any issues with the Regen. Additionally, the oil changes are not an issue. I have it changed every 5000 miles at the dealership I purchased the truck at. Maybe I’m being conservative, as the oil percentage left indicator is usually still showing around 45 percent. DEF usage is very good when not towing. Lastly, GMC has done an excellent job soundproofing the cabin. My wife even commented when we first drove the truck off of the dealer lot how quiet and smooth riding the truck was. Thanks for your excellent videos and reviews of this powerplant. We are so happy with our truck!!
Owned the 3.0 duramax for a year, never saw any message about keep driving due to regen. Def filling isn’t a pain, so easy , done in a couple mins. I don’t tow a lot so def last a while. Great engine , great mpg for a Yukon !
I've had my 3 litr LZO two years now with 33,000 miles on it and I love this engine. It is the most refined diesel you will ever drive, smooth,quiet, powerful. GM did a great job designing this engine for the 1/2 ton truck. We have a cottage 287 miles from our home and I'm consistently getting 27-28 mpg's round trip.
I eventually got my own 3.0L this year, and I absolutely love it! Everything you said is spot on, and people really need to just not be afraid of it. It's an absolutely amazing engine, and I look forward to many, many years of great mileage out of it.
I have a LZ0 .. 2023 ... best 39.2 mpg average 32 with winter it goes down 25 mpg ... used 6 gallons of def in a years time ... I also run hot shots fuel additives 2oz per 1/4 tank ... love this truck ... was a good investment...
One of your better videos. The only omission/correction I would add relates to cold weather. As someone who lives 130 miles outside of Fairbanks, Alaska, I find that all diesels these days start just fine without being plugged in even down to -40, at which point plugging in helps. Block heaters do greatly reduce cold-start wear, however. What will shut down a diesel in the winter is improper winterization of the fuel. If you fill up during the shoulder season and the station has not switched to the appropriate blend of No. 1 Diesel/No. 2 Diesel, it can catch you during a cold snap. Likewise, if you use the huge range many of these vehicles have and think you will fill up in balmy Washington state and save by not refilling until you get to Grand Prairie, you may find yourself at the side of the road. We have lows of 2 deg F coming up tomorrow, and I made sure to keep my vehicle's fuel tanks low so I can fill with the appropriate winter blend.
I am so relieved they’re keeping it. I have a 2021 with 75k miles and no issues with the engine. Came from a Ram 1500 with the Ecodiesel (no issues either). Tows my boat great, I use the payload for work, and great MPGs all around. Best 1500 engine combo.
I don't have this particular engine but I do have a small diesel motorhome that requires DEF. I buy most off my DEF at truck pumps. Put the nozzle in the DEF tank fill opening and pull the handle just like a fuel pump. It will auto shut off just like a fuel pump. A lot simpler than the plastic jug and less packaging waste.
I own a 2023 Silverado 1500 LZ0 and it is the best engine ever. I will see 30 mpg SLC to DEN, 700 miles of range I can do the trip on one tank. Crazy. Quiet, powerful and smooth 10 speed.
I'm on my second 3.0 truck and so far so good. My first was a 2020 GMC and I traded it in with around 45,000 miles without any issues. My current truck is a 2024 Chevrolet and I tossed around the idea of going with a 6.2 before buying another 3.0 but the fuel mileage difference along with using premium gas with the 6.2 is a no brainer..
As an owner of a 2022 3rd gen ecodiesel, i hear the same things about what to not do with them. As with the gm baby duramax, there are 0 issues with the gen 3 ecodiesel and engineers also say to drive them. Also a great truck and i will get a gmc when i need a new 1500 diesel within the next 10 years since ram stopped making them :(
We have two... one an Lm2 in a 2021 At4 and the the thing runs so good we bought a 2023 Yukon. Still have both and zero issues. DEF usage isnt worth discussing. We love those rigs
Another thing to be weary of is the DEF fluid freezing. We’ve got -16* now and before the freeze, mine was reading that it’s used up 3 bars. With the freezing temps, now it’s showing that the DEF is full.
Well done! Very good information as I give the go ahead to my local dealer to order the GMC Yukon Denali with the diesel engine. Thank you for sharing!
Great video, Tim. I have just over 10,000 miles on my 24 AT4 3.0L and absolutely love it. Best engine I've ever owned. Agree with you on regen. I stressed about it early on, but don't give it a second thought now. Nearest Top Tier to me is about 1000 miles away. Recently started using Archoil AR6400-D diesel cleaner every 5000 miles. Small increase in mpg but a pretty healthy increase in miles between regens.
Very happy with our 2022 suburban LM2. No issues but only 24k miles. I think it regens about every 400 miles. I can tell when it is doing a regen by the exhaust sound and high idle when stopped. I buy the Walmart DEF for 8.88 and no issues. Use mobile 1 esp x2 DexosD oil from Walmart for oil changes. Hot shots EDT fuel additive to keep everything clean. Also have a 3.0 inline 6 twin turbo diesel in my old bmw with 162k miles on it. Its a blast to drive with 364whp/595lb torque in a small 3 series (stage 2+ tune). Pulls a mid 12 second quarter mile at 111mph trap speed. Fun fact, the fastest 335d 3.0 diesel in the US is pushing over 1000whp with triple turbos and nitrous.
The question that comes up is whether people prefer comfort or reliability? Noise level comfort over reliability is a choice only few people make. There’s also issues like transmission leaks and wiring harness issues and parts availability issues. Because if the vehicle requires maintenance then it’s going away for a decent amount of time unfortunately. I really hope you make a video about these issues too.
Just picked up a '23 Silverado and love this motor! 30mpg most of the time without even trying. my old f-150 5 liter averaged 17. Solid power with a smooth 10spd tranny. I've owned a 6.6 duramax in my past and while a decent motor I'll take an inline cylinder config over a V any day. Problem with putting a diesel into soccer mom rig SUV's is gas in the diesel tank.. so many people are going to do that!
13:48 It’s common in the oil and gas industry to live out of a truck, so the they often idle for days. Run into town for fuel and food, then back out to location. Wasn’t an issue back in the day with diesel trucks, but now there are a lot of issues with emissions systems. A lot of companies will now run gas 3/4 tons if they don’t haul much or often. Cheaper up front and lower fuel and maintenance costs. We aren’t shutting off trucks when it’s 115 outside or freezing. Just let the thing run so it’s comfortable when one catches a break. Not to mention laptops in the trucks that need to stay on 24/7
Hey I’ve found your channels and watched a few videos you’ve made specific to this 3.0. Have you ever asked the big brains about the auto start stop in these? I understand they wouldn’t equip if it was harmful however i wonder if it’s something we should keep activated all the time or know when to use it.
2023 AT4, 48000 miles. Loved the truck. Religious maintenance. No heavy towing, or off roading. Turbo blown. Waited 3 MONTHS for new unit, just came into the dealership. Still waiting to get the truck back.
Thank you for this video. Hope others watch it if they are on the fence with the diesel because you nailed it on the head. Bought a used 2021 with the LM2 not knowing anything about diesel trucks, but did plenty of research. I’ve put about 25k on it, and as long as they keep making them, I’m buying. Love everything about it, and everything you said in the video about regen, cold starts, def, etc, I agree 100%. I average about 21 mpg because of mainly city driving, but have hit 34. My 5.3? Best was about 26, average of 14. Never looking back.
My Brother bought a 22 GMC Sierra with the 3.0 Duramax. So far he loves it. The fuel economy he loves, getting close to 30mpg unloaded. He said it tows great for what he needs. We never tow more than about 6k lbs. His is an X31 4x4 Elevation Black. Nice truck.
I own a 2024 GMC Denali Ultimate with the 3.0 LZ0 and it's my favorite part of the truck! Well, that and suoer cruise...lol. The Denali is hamds down my favorite truck of all time!!
30 years of driving Ford trucks and I just bought a 25 Elevation LZ0 and max trailering. My first impressions are very positive, with 25-27 MPG. Power seems good, although going easy on it with only 350 miles on it currently. Can't wait to start towing with it!
THANK YOU for saying regen is a non issue! I never understood everyones concern with it and did a lot of research before buying my 3.0 Duramax and still never understood it. I guess if you do a lot of short trip driving it could be an issue. But I live in the country and drive 45 min @75mph+ to town a few times a week. No idea when it's doing a regen, doesn't affect me. Unless you do mostly short 5-10 min drives it's nothing you ever need to even think about. If you do short drives all the time, that is bad for any engine. Even a gas vehicle needs longer drives to heat up and burn moisture and gas out of oil, get catalytic converter hot enough to burn off and not clog up. If you always drive short distances, that is where electric cars actually are superior!
Love this motor. 72k miles on a 2023 AT4 LZ0 withdrew cab and standard bed. 25 mpg lifetime average and some trips into the 30’s. Only issue is waiting on backordered engine coolant pump for a month while it sits waiting on warranty work.
While driving my commute, it's easy to see when a regen cycle is running by the mpg. I'll see a drop of mpgs by 3 or 4 during my 20 mile commute via freeway.
I towed 36ft 7800lbs plus all the kids clothes toys pots& pans trailer all over this country with 2023 3.0. X31 not a problem just got heavy on def but flew up and down the hills no problem love it
I sold a lb7 w 380k about a year ago and I absolutely loved it! I'll be replacing it this spring but I'll be buying a gasser this time because I just don't want the potential dpf issues because it doesn't seem like "if" but "when"...
I've been driving diesel pickups since 2000 and the best advice I got way back then was from a guy who had been driving Mercedes diesels since the early 70's. His advice was to always buy fuel from a station that is a name brand and that you know sells LOTS of diesel fuel so it isn't sitting in those tanks for any length of time. Knock on wood I've never had a fuel problem in all those years.
Very good advice. Where I live, aside from the truck stops, the highest volume diesel fuel retailer in town is a "regional" brand fuel station, but I also know where they source their diesel fuel--it all comes from the same refinery serving the national chain stations. Never had a fuel quality issue with them.
I bought my first baby diesel earlier this month after watching most of your videos about this engine. I don’t regret my purchase and absolutely love this truck.
Great video! Everything you said is 1000% true and accurate. I have a 2024 LZO and love it. 27 mpg combined and over 30 mpg on the highway frequently. Awesome truck and love the In-line 6 Deisel. Smooth and runs on the highway in 10th gear and 1500 rpm’s at 73 mph. Engine should last over 1,000,000 miles and that cruising rpm’s. DEF and regeneration are NOT in issue. Without towing I think you will get 6,000++ miles before the truck needs DEF.
I like this video. I've been tossing around getting a GMC with the 3.0 diesel because I've heard such good things about it. All the other engines I really don't know. Fords with similar features are about $6,000 more. I like the look of the Ford F-150 Platinum better but the Sierra 1500 is a pretty nice looking truck. I'm not concerned about the wet belt. If the engine goes 200,000 miles and 15 years it's a good time to do a really thorough once-over anyway. This was a really great video and I definitely feel confident if I go with that engine. It would be my first diesel.
I've got a 23 Silverado with the LZ0 3.23 gears towing is 9300. Heavy duty towing package brings towing just over 13000 lbs with the corresponding hit to your mileage.
I havent really noticed much of a hit on my fuel economy with the max tow 3.73's. If I had to drive 80 mph like the city guys do, it might burn more fuel, but cruising at 65 mph I average around 28 to 30 mpg with my all time best being 35 mpg average on very flat terrain during a 50 mile trip. 2024 Silverado LTZ CC 6.5 ft bed with max tow.
Tim, GM doesn't make the Delco diesel fuel additive anymore. Part #10-1034 has been discontinued. Since GM doesn't recommend any other, what should owners do? Maybe you could ask GM. The owners manual says to use it.
I talked to you over email before ordering my 23 Yukon Denali Duramax. 25k miles later no issues. Absolutely love the engine. Great power and torque. Much more lively than our previous gen Yukon with the 5.3. The 6.2 is nice, but lots of lifter issues noted. We are getting 25mpg lifetime mixed driving. Highway as high as 31. Around town 24-27mpg. Such a nice powertrain. I do use EDT additive at every fillup.. I figure it can’t hurt. I hope GM keeps making the 3.0. My next SUV will more likely be the z71 suburban Duramax. Thanks for the great diesel content.
Check the oil for the first ten thousand miles, mine drank an extra qt the first two oil changes. At 20,000 miles with zero issues. Pulls like a mule and sips fuel. It also starts great in negative temps.
I own a 2020 Sierra with this engine. It's awesome! I have 70,000 miles on it. Maintenance is simple. Oil changes, DEF, tires etc. No appreciable differences in terms of cost over my previous gas engine vehicle. In warmer weather I get 30mpg in the highway. I could not be happier. I had a diesel vehicle in the 1980's. It was prone to fuel jelling in cold weather and it smelled. This Duramax has none of those issues.
I would caution people to avoid 2019-21 trucks with 100k+ miles or negotiate price carefully. Those years tend to have more issues with timing chain wear. It's an expensive repair (approx 40 hours of labor). Some guys dont have the issue, others bought a used truck with 100k miles and eventually get the CEL code due to timing chain wear. Newer trucks with high mileage dont seem to have the issue, so they either changed the tensioner to put less stress on the chain or they improved the chain itself.
Great video! I agree with everything you say. I have 24 ZR2 3.0L. I use it for work in ag consulting business. I had a 2023 ZR2 with 6.2L. I averaged 15 MPG with a little over 300 mile range. Had to use 93 octane. Now I average 22 MPG with 500 mile range. Diesel is $0.30- $0.40 cheaper than 93 octane in TX. I use 1 gal DEF per 800 miles. No big deal. I change oil at 5K and it’s down a quart. If I had to add a quart no big deal. I drive 50% off road, idle a lot with AC on in 90-105F heat. No issues through 12K miles. This truck gets me anywhere in any condition; mud, sand, snow, pivot tracks. Oil change is about $30 more than 6.2L. And I’ll trade it off before 200K!
I have a 60mile one way commute to work. I think i have found a sweet spot with this 3.0 (mine is LM2) with my usage. I get 30mph on average and have refilled DEF at a truckstop from the pump twice in about 15k miles so far. Actually measuring my usage on this tank of DEF. I have yet to tow, so no data on that.
Love my LM2...had it now 60k km and have only had oil changes and put DEF in every 5-6k km. Crazy good mileage. Only downside I have so far is the higher price of oil changes (roughly double).
I have this engine in my 2024 Sierra SLT. It is an absolutely amazing engine. I drove from Alaska to southern Arizona a few weeks ago and fuel mileage was amazing. I topped off before leaving Alaska and I needed only three fill ups to get through Canada. Another three fill ups in the Lower 48 got me all the way to my destination southern Arizona and I still had half a tank left. I can't say enough good things about this truck and its engine. I loved the 6.2L in my 2019 Silverado, but it just doesn't compare to my 3.0L.
I have a 2022 Suburban with the 3.0 duramax. 50k miles on it and not a single issue. Routinely get 20 city and 25 highway. And lately diesel fuel is cheaper than super unleaded. No regrets at all.
Very interesting! My experience with most diesels are they can “gel” with cold weather? I presume plugging them in prevents this? Also cost benefit vs gasoline engine? Diesel is more expensive! I live in Montana and grew up in South Dakota! So I’m hesitant with diesel and turbos!
I have 5k on a 5/24 Sierra 1500 SLE. Best driving vehicle I have used. It would be very useful to have an indication of regen built in as you could then make the decision to finish before shutting it off. Without the iDash you would never know. Yes it picks up seamlessly after shutdown or long idling. Also a DTE for DEF would be nice. After pulling high drag enclosed trailer DEF DTE went to 125 miles while pulling then back to 1213 after no pulling it with a startup popup EVERY time until added 2 gallons. For that matter, a service menu BUILT in to nearly eliminate any need for scan tools.
I have a 2020 Sierra with the 3.0 and love it. Great fuel economy and with it mated with the 10 speed the power is very linear feeling. Pulling my 5500 camper it is always in the right gear.
Very good video, Tim. Almost bought a GMC Sierra Denali with the LZ0, but in 2022 GM was missing too many options on them due to the chip and parts shortages. Ultimately went with the Tundra. Love it, but the engine recall sucks.
So looking at the chevy 150o with the 3.0 vs ford 3,.5 powerboost. As a daily driver. Which one will be better for someone who doesn't drive very much but wants the best fuel economy?
I love this in my Sierra and was hoping to get my wife a 3.0 in a 2025 Yukon Denali Ultimate…but GMC isn’t offering it in the top trim next year. A huge mistake IMO.
Alright so I have some questions. In terms of cost: How does it compare to the turbomax 4 cylinder? Horsepower and torque seem similar? Here in Ohio diesel typically runs $0.50 over 87 octane gas. Based on 25000 miles per year numbers look pretty close. Which is more reliable? Would you buy a used one? I am looking for bang for the buck
never bought a american vehicle but watching your video, and having the need for a truck that can tow my small camper and be a commute vehicle the 3.0 was a no brainer
I have a 2021 GMC 1500 AT4 with a Duramax and use it for work so it has 115,000 miles on it. Just like a two thousand miles of that towing. I beat it up but make sure it is maintenanced and taken care of that way. I have not had a problem with it and I have never heard it regen. The dealership had to put in a new glow plug and they paid for it. Also had a weird steering thing happen to it but that went away. And that is it. I live in South Dakota so when it gets down to single digits and below zero I plug it in and it never has problems starting. It is a really good truck and when I get it paid off I would like to get the same one but a Denali and use that for my non-work trips!
I came from your other video but thank you for this video too. I'm new to learning about cars but I've watched many car enthusiasts like Joe Raiti, Sofyan, and Doug's videos regarding the duramax engines in the Tahoes being really good but never understood the DEF system, regen, etc. Thanks for going into more detail, this makes me feel comfortable about buying the duramax engine option. The mpg's are much better on this option which I love, but I do know it's much more maintenance than the 5.3L or 6.2L options. Diesel is not that bad either, I'm in California and at the shell gas station it's $3.05 right now which is better than the $4.29 I filled up at today lol.
You hit on the major question about the economics of owning a diesel vehicle. There is a WIDE disparity between diesel fuel and gasoline fuel costs by area. Where I live, diesel fuel is MUCH more expensive than gasoline currently, up to 40% more expensive than gasoline per gallon at some stations. The blows the fuel cost advantage of the diesel pickup out of the water compared to gasoline powered pickups, even though the gasoline pickups get lower fuel economy. Interestingly, diesel fuel is much more costly where I live because it is a farming area with very high diesel fuel demand for both farming and trucking.
Diesel near my home~ 60 cents/gal more than reg (87) gas. 50 miles away and different state near my workplace, diesel is up to 30 cents more than reg. Gas but the same price as reg near my home. My state has fairly high taxes on diesel vs gas. In my 25 years of diesel ownership, I’ve seen it 50 cents or so less than reg and $1.50 or more higher than gas. On the plus side, local stations don’t “usually” jack the price up every Thursday on diesel.
@@rockymountainjazzfan1822 Wow. Thanks for the feedback. Which truck do you think is better to own gas or diesel? Or it is based on your lifestyle and how you plan to use the vehicle?
@@jeffs2809 Interesting. I know prices will vary depending on where you live out so I was surprised to see that it was cheaper in my area, considering i'm in California. Do local stations also sell Top Tier Diesel?
@@koharu.mochii I have no top tier diesel anywhere nearby. Several top tier gas pumps but none of them carry top tier diesel. I have one station that carries a "premium diesel", but the US doesn't really have a standard for what that is. They claim a higher cetane and additive package & I've never had an issue with their fuel. It's always about the same price as the other stations in that area. Around $3.59 a week or 2 ago. Stations near my office are around $3-$3.20.
Get ready for your coolant control flow valve to fail. Do yourself a favor and order that part now. Mine failed at 45k miles and many many others have too. 3-5month wait time for the replacement part. I have a70k dollar paperweight until sometime in February.
One correction on the idling & regen. The Ford f-350 I drive at work will go into regen at idle and has many times. The engine speed increases & it does its thing. It definitely takes longer than a driving regen, but still gets it done. From memory, I believe Ram will also do parked regens, but I don’t know for certain when that strategy was implemented.
I have a 2020 Sierra with 52K. First diesel I have ever owned and wouldn't consider any other engine on my next vehicle. This thing has great fuel mileage and plenty power for towing.
Same here. I just got a loaded up LT Trail Boss midnight edition coming out of an RST.. absolutely love this truck and the 3.0 with the 10 speed trans is the best!
Have a 23 trail boss with the LZ0. My first diesel as well. Have done two oil changes on it already with then 5,800 miles on it. I’m already at 80% and haven’t put a thousand miles since last oil change. Any input greatly appreciated. Been subscribed to this channel for a while.
@@Pickuptrucktalkthanks for response Tim. I have only towed once with it to be honest. Love the truck but can’t understand the oil situation. Dealer told me it’s a very thin oil they use and is calculated on how many starts etc I do on a daily basis. Could not find a number for GM Tech support direct. I have my 2012 Tundra I’ve been using for towing a 14’ tandem trailer. Own a kitchen cabinet business and use trailers versus box trucks for deliveries which was the main purpose of buying a diesel. Looking to trade Tundra and wife’s 2008 4Runner in to get something newer for her.
@@Pickuptrucktalk using it as a daily driver for the most part a lot of stop and go a few miles here and there. Some highway driving but mostly small town driving.
I have a 23 with LZ0 my regular drive is 183 miles I do it twice a week. 40,000 miles. with no problems. Average 32MPG. Love this truck!
Best engine GM has developed in decades.
1000% agree.
Almost got 800miles to a tank a few times. Works great at high altitudes too, had mine over 10k feet elevation a few times. 2024 TB slate gray
I agree and I've owned everything from the 4.3-6.2.
Agreed love my 2024 gmc sierra 1500 Denali best truck on the market and good dealers are doing crazy discounts and incentives and interest rates. Saved 15k plus Costco 1k incentive and vet incentive $500 paid with extended warranty and maintenance plan 80k all in.
I've been with GM Fleet and Commercial Sales since 1997. On my 2nd one now. 2023 Crew LZO. Best engine we've produced. I tow my 5,000 bass boat, get 20 mpg and can't even tell it is back there. Way over 30 mpg highway. Never go back to gas!!
Thank you for putting this together! I just bought a 24 AT4 with 3.0 diesel. I love the truck. I watched a bunch of your videos as well as DemonWorks before I made my move. I couldn’t be happier. Thanks for your input and insight. 🙏🏻
How’s your experience so far ?
@ The truck runs flawlessly. I don’t have a need to tow so it’s just a commuter, with that said, it’s quiet, has a nice ride and gets between. 25-30 mpg regularly. Came from a Tacoma so it’s so much more roomy and plush. A nice ride height allows for great road vision. No regrets so far. Only once flaw I have observed, the backup camera is NOT good at night. Totally useless. I typically get 600+ miles to a tank and it hardly uses DEF.
Pronlem is every modern diesel i have owned..many...all had issues with dpf...
Just bought a GMC Sierra Denali with the Duramax. First diesel vehicle ever and I’m definitely loving it. Thank you for the video. First 200 mile round trip I got 35 mpg, I was blown away.
Same here! I use to have a 2013 5.7 v8 Tundra and I miss the power but I don’t miss the mpg.
I got a 22 gmc Denali diesel, and I LOVE IT.
Great video Tim.
Just a note about fuel economy and DEF usage. I had a ‘23 Sierra 1500 AT4 3.0 Duramax (LZ0). When towing, even a small increase in speed dramatically changes your diesel/DEF consumption. I’m up in Canada and I found the towing sweet spot with that truck / engine was between 100-105 km/h (~63mph). Towing between 3,500 - 5000 lbs at that speed, the mileage/DEF consumption was great. When I set the cruise at 110+km/h (~70+mph) the fuel/DEF consumption was alarming. As you state it absolutely drinks DEF, I actually ran my DEF tank empty once on a trip because I didn’t realize how fast it was hammering through it. That’s just how it is when towing…if you can back off the speed a bit, it makes a huge difference. Otherwise, crack open the wallet and get ready to pay.
I had to move on from the ‘23 Sierra, living in Northern Canada(Northwest Territories) with extended periods of extreme cold I had some problems my dealer/GM could not solve with the LZ0. Other than that, that truck engine combo was just excellent.
I have ‘24 2500 Sierra AT4X with the 6.6 now and it’s the same story with fuel/DEF usage. Keeping that truck below 70mph makes a huge difference when towing. I just did a 4,500 mile road trip, towing the whole way (4000lb enclosed), and when I cruised under 110km/h (70mph), the truck got great mileage and was easy on DEF. At some points when I just wanted to make some time up, it hammered through DEF and diesel. I knew it and I was ok with it.
Enjoy the channel and your videos Tim, keep up the good work.
Dave
Have had exactly the opposite experience with the LZ0
As I posted elsewhere, DEF usage is essentially correlated to fuel consumption. More fuel consumption = more DEF consumption. Put simply, if you double the fuel consumption of the engine, you will likely double DEF consumption as well.
I have 24’ 2500 sierra at4 dmax have got it down driving on highway to 8.6/100 what I noticed long drives on the highway the truck sips fuel and anything in town I just drinks it lol overall no complaints.
I had a 2020 Silverado 1500 and currently have a 2022 Suburban with the 3.0 LM2 motor. Neither burned a drop of oil in 5,000 mile oil change. Also, the DEF usage was reasonable. This is an awesome motor.
My 2024 hasnt burned any thus far. Most oil consumption issues were with the LM2 due to valve covers having bad internal welds that allowed oil to get sucked into the intake. That also caused many other rumored issues that get spread on the internet. The oil would foul glow plugs and ruin the emissions system. To make things worse, some dealers and guys doing their own oil changes were using Dexos oil for gas engines instead of DexosD oil meant for this engine. The gas engine oils have higher ash content that is terrible for catalyst and filter.
I have a 2020 with the LM2 and have put 92k on it so far. Never seen the inside of a dealership garage. Just oil changes/fuel filter changes. Great engine!
I just made a three hundred mile trip in my new Yukon SLT with the 3.0 and got 28.2 MPG.
Just turned over 1K miles on my new 24 GMC Denali 3.0. Went on a trip yesterday in the hills and turns of Eastern Ohio and Western PA - Avg'd. 33.2 mpg. First diesel I've had and NO regrets. I know it's new, but from what i'm seeing now, I don't vision going back to gas anytime soon. THANKS Tim, great video!!
Based partly on your videos, we pulled the trigger on this engine in a 2023 Sierra SLT. This 3.0L diesel mated to the 10 speed tranny is a dream to drive. I’ve never noticed any issues with the Regen. Additionally, the oil changes are not an issue. I have it changed every 5000 miles at the dealership I purchased the truck at. Maybe I’m being conservative, as the oil percentage left indicator is usually still showing around 45 percent. DEF usage is very good when not towing. Lastly, GMC has done an excellent job soundproofing the cabin. My wife even commented when we first drove the truck off of the dealer lot how quiet and smooth riding the truck was. Thanks for your excellent videos and reviews of this powerplant. We are so happy with our truck!!
Owned the 3.0 duramax for a year, never saw any message about keep driving due to regen. Def filling isn’t a pain, so easy , done in a couple mins. I don’t tow a lot so def last a while. Great engine , great mpg for a Yukon !
I did due to short trips. It def happens but if you don’t do short trips, you won’t have any message!
I've had my 3 litr LZO two years now with 33,000 miles on it and I love this engine. It is the most refined diesel you will ever drive, smooth,quiet, powerful. GM did a great job designing this engine for the 1/2 ton truck. We have a cottage 287 miles from our home and I'm consistently getting 27-28 mpg's round trip.
2024 LZ0 models had check engine light issue related to regen until TSB came out in May for an update to the ECM. No problems after the update so far.
Same here. I had a CEL at 3000 and then again at 8000. Got tge TSB done, and I'm at 10500 without any more CEL's
I had the same issue with my 2024. But the engine is awesome since.
When mine hit 6500 miles I had a problem with my tra then 2500 miles later the ola went out
I'm not a GM guy but this engine is a masterpiece. Great fuel economy, great power, low upfront cost.
These are amazing trucks.
21 Elevation with 42K miles trouble free.
Very happy customer.
I eventually got my own 3.0L this year, and I absolutely love it! Everything you said is spot on, and people really need to just not be afraid of it. It's an absolutely amazing engine, and I look forward to many, many years of great mileage out of it.
I have a LZ0 .. 2023 ... best 39.2 mpg average 32 with winter it goes down 25 mpg ... used 6 gallons of def in a years time ... I also run hot shots fuel additives 2oz per 1/4 tank ... love this truck ... was a good investment...
One of your better videos. The only omission/correction I would add relates to cold weather. As someone who lives 130 miles outside of Fairbanks, Alaska, I find that all diesels these days start just fine without being plugged in even down to -40, at which point plugging in helps. Block heaters do greatly reduce cold-start wear, however.
What will shut down a diesel in the winter is improper winterization of the fuel. If you fill up during the shoulder season and the station has not switched to the appropriate blend of No. 1 Diesel/No. 2 Diesel, it can catch you during a cold snap. Likewise, if you use the huge range many of these vehicles have and think you will fill up in balmy Washington state and save by not refilling until you get to Grand Prairie, you may find yourself at the side of the road. We have lows of 2 deg F coming up tomorrow, and I made sure to keep my vehicle's fuel tanks low so I can fill with the appropriate winter blend.
I am so relieved they’re keeping it. I have a 2021 with 75k miles and no issues with the engine. Came from a Ram 1500 with the Ecodiesel (no issues either). Tows my boat great, I use the payload for work, and great MPGs all around. Best 1500 engine combo.
I have a 23 and couldn't be happier.
I don't have this particular engine but I do have a small diesel motorhome that requires DEF. I buy most off my DEF at truck pumps. Put the nozzle in the DEF tank fill opening and pull the handle just like a fuel pump. It will auto shut off just like a fuel pump. A lot simpler than the plastic jug and less packaging waste.
I love my 2023 Duramax. I bought it after watching your videos.
Thanks Tim, good to see you’re still making the 3.0L videos.
I own a 2023 Silverado 1500 LZ0 and it is the best engine ever. I will see 30 mpg SLC to DEN, 700 miles of range I can do the trip on one tank. Crazy. Quiet, powerful and smooth 10 speed.
I'm on my second 3.0 truck and so far so good. My first was a 2020 GMC and I traded it in with around 45,000 miles without any issues. My current truck is a 2024 Chevrolet and I tossed around the idea of going with a 6.2 before buying another 3.0 but the fuel mileage difference along with using premium gas with the 6.2 is a no brainer..
I really hope GM keeps this motor running for at least another decade or longer. Long as they have this motor they’ve got a customer in me.
Thank you for doing this. I had questions on some of those topics. Looking forward to pulling the trigger on a 3.0 LZO asap.
As an owner of a 2022 3rd gen ecodiesel, i hear the same things about what to not do with them. As with the gm baby duramax, there are 0 issues with the gen 3 ecodiesel and engineers also say to drive them. Also a great truck and i will get a gmc when i need a new 1500 diesel within the next 10 years since ram stopped making them :(
Great video! Thank you! Recently purchased a 2025 Silverado 1500 with the 3.0 Duramax.
Bought a 2024 3.0 ZR2 Duramax. Will only buy 3.0s from now on.
We have two... one an Lm2 in a 2021 At4 and the the thing runs so good we bought a 2023 Yukon. Still have both and zero issues. DEF usage isnt worth discussing. We love those rigs
Another thing to be weary of is the DEF fluid freezing. We’ve got -16* now and before the freeze, mine was reading that it’s used up 3 bars. With the freezing temps, now it’s showing that the DEF is full.
Well done!
Very good information as I give the go ahead to my local dealer to order the GMC Yukon Denali with the diesel engine.
Thank you for sharing!
Thanks for providing this information. It is nice to have someone putting things in simple terms.
Great video, Tim. I have just over 10,000 miles on my 24 AT4 3.0L and absolutely love it. Best engine I've ever owned. Agree with you on regen. I stressed about it early on, but don't give it a second thought now.
Nearest Top Tier to me is about 1000 miles away. Recently started using Archoil AR6400-D diesel cleaner every 5000 miles. Small increase in mpg but a pretty healthy increase in miles between regens.
Very happy with our 2022 suburban LM2. No issues but only 24k miles. I think it regens about every 400 miles. I can tell when it is doing a regen by the exhaust sound and high idle when stopped. I buy the Walmart DEF for 8.88 and no issues. Use mobile 1 esp x2 DexosD oil from Walmart for oil changes. Hot shots EDT fuel additive to keep everything clean.
Also have a 3.0 inline 6 twin turbo diesel in my old bmw with 162k miles on it. Its a blast to drive with 364whp/595lb torque in a small 3 series (stage 2+ tune). Pulls a mid 12 second quarter mile at 111mph trap speed. Fun fact, the fastest 335d 3.0 diesel in the US is pushing over 1000whp with triple turbos and nitrous.
Best engine I’ve ever had…..
The question that comes up is whether people prefer comfort or reliability? Noise level comfort over reliability is a choice only few people make. There’s also issues like transmission leaks and wiring harness issues and parts availability issues. Because if the vehicle requires maintenance then it’s going away for a decent amount of time unfortunately. I really hope you make a video about these issues too.
Just picked up a '23 Silverado and love this motor! 30mpg most of the time without even trying. my old f-150 5 liter averaged 17. Solid power with a smooth 10spd tranny. I've owned a 6.6 duramax in my past and while a decent motor I'll take an inline cylinder config over a V any day.
Problem with putting a diesel into soccer mom rig SUV's is gas in the diesel tank.. so many people are going to do that!
13:48 It’s common in the oil and gas industry to live out of a truck, so the they often idle for days. Run into town for fuel and food, then back out to location. Wasn’t an issue back in the day with diesel trucks, but now there are a lot of issues with emissions systems. A lot of companies will now run gas 3/4 tons if they don’t haul much or often. Cheaper up front and lower fuel and maintenance costs. We aren’t shutting off trucks when it’s 115 outside or freezing. Just let the thing run so it’s comfortable when one catches a break. Not to mention laptops in the trucks that need to stay on 24/7
Hey I’ve found your channels and watched a few videos you’ve made specific to this 3.0. Have you ever asked the big brains about the auto start stop in these? I understand they wouldn’t equip if it was harmful however i wonder if it’s something we should keep activated all the time or know when to use it.
I’ve never had a better feeling engine and truck than my LZ0
2023 AT4, 48000 miles. Loved the truck. Religious maintenance. No heavy towing, or off roading. Turbo blown. Waited 3 MONTHS for new unit, just came into the dealership. Still waiting to get the truck back.
Thank you for this video. Hope others watch it if they are on the fence with the diesel because you nailed it on the head.
Bought a used 2021 with the LM2 not knowing anything about diesel trucks, but did plenty of research. I’ve put about 25k on it, and as long as they keep making them, I’m buying. Love everything about it, and everything you said in the video about regen, cold starts, def, etc, I agree 100%.
I average about 21 mpg because of mainly city driving, but have hit 34. My 5.3? Best was about 26, average of 14. Never looking back.
My Brother bought a 22 GMC Sierra with the 3.0 Duramax. So far he loves it. The fuel economy he loves, getting close to 30mpg unloaded. He said it tows great for what he needs. We never tow more than about 6k lbs. His is an X31 4x4 Elevation Black. Nice truck.
I own a 2024 GMC Denali Ultimate with the 3.0 LZ0 and it's my favorite part of the truck! Well, that and suoer cruise...lol. The Denali is hamds down my favorite truck of all time!!
30 years of driving Ford trucks and I just bought a 25 Elevation LZ0 and max trailering. My first impressions are very positive, with 25-27 MPG. Power seems good, although going easy on it with only 350 miles on it currently. Can't wait to start towing with it!
THANK YOU for saying regen is a non issue! I never understood everyones concern with it and did a lot of research before buying my 3.0 Duramax and still never understood it. I guess if you do a lot of short trip driving it could be an issue. But I live in the country and drive 45 min @75mph+ to town a few times a week. No idea when it's doing a regen, doesn't affect me. Unless you do mostly short 5-10 min drives it's nothing you ever need to even think about. If you do short drives all the time, that is bad for any engine. Even a gas vehicle needs longer drives to heat up and burn moisture and gas out of oil, get catalytic converter hot enough to burn off and not clog up. If you always drive short distances, that is where electric cars actually are superior!
Love this motor. 72k miles on a 2023 AT4 LZ0 withdrew cab and standard bed. 25 mpg lifetime average and some trips into the 30’s. Only issue is waiting on backordered engine coolant pump for a month while it sits waiting on warranty work.
I plan to pick up a 25 Yukon Denali in about 5 years used. Gunna put a 5’ straight pipe on it.
While driving my commute, it's easy to see when a regen cycle is running by the mpg. I'll see a drop of mpgs by 3 or 4 during my 20 mile commute via freeway.
Thanks so much for posting this video. I’m on the fence about trading my Ram Hemi for a GMC with the Duramax. This was very helpful.
I towed 36ft 7800lbs plus all the kids clothes toys pots& pans trailer all over this country with 2023 3.0. X31 not a problem just got heavy on def but flew up and down the hills no problem love it
Great explanation and dispelling the myths of modern diesels
I sold a lb7 w 380k about a year ago and I absolutely loved it! I'll be replacing it this spring but I'll be buying a gasser this time because I just don't want the potential dpf issues because it doesn't seem like "if" but "when"...
I've been driving diesel pickups since 2000 and the best advice I got way back then was from a guy who had been driving Mercedes diesels since the early 70's. His advice was to always buy fuel from a station that is a name brand and that you know sells LOTS of diesel fuel so it isn't sitting in those tanks for any length of time. Knock on wood I've never had a fuel problem in all those years.
Very good advice. Where I live, aside from the truck stops, the highest volume diesel fuel retailer in town is a "regional" brand fuel station, but I also know where they source their diesel fuel--it all comes from the same refinery serving the national chain stations. Never had a fuel quality issue with them.
Very good and informative video. I have 2024 Chevy duramax, no complaints. I love it ❤❤❤
This is the only engine I have been excited about in the recent years. I honestly wouldn’t be shopping for a truck if it wasn’t for this engine.
I have a Ram eco diesel.No issues good mileage & 10,000 pound towing. As Ram discontinued the 3.0L my next truck will likely be a Duramax 3.0.
50000 miles per year, 30K forward drug truck. Open great noises thank you man we're all you information❤
I bought my first baby diesel earlier this month after watching most of your videos about this engine. I don’t regret my purchase and absolutely love this truck.
Just got a 2025 High Country Duramax 6.6L. We dont own a trailer. Its for the boss to own and enjoy. Yes it was worth it.
2024 Sierra 1500 3.0 diesel is a very nice truck! Just over 30,200 miles and loving it.
Great video! Everything you said is 1000% true and accurate. I have a 2024 LZO and love it. 27 mpg combined and over 30 mpg on the highway frequently. Awesome truck and love the In-line 6 Deisel. Smooth and runs on the highway in 10th gear and 1500 rpm’s at 73 mph. Engine should last over 1,000,000 miles and that cruising rpm’s. DEF and regeneration are NOT in issue. Without towing I think you will get 6,000++ miles before the truck needs DEF.
I like this video. I've been tossing around getting a GMC with the 3.0 diesel because I've heard such good things about it. All the other engines I really don't know. Fords with similar features are about $6,000 more. I like the look of the Ford F-150 Platinum better but the Sierra 1500 is a pretty nice looking truck. I'm not concerned about the wet belt. If the engine goes 200,000 miles and 15 years it's a good time to do a really thorough once-over anyway. This was a really great video and I definitely feel confident if I go with that engine. It would be my first diesel.
You can tell when the trucks doing a regen by the temp gauge it jumps up about a needle width and sometimes you can smell it that's how I know ....
I've got a 23 Silverado with the LZ0 3.23 gears towing is 9300. Heavy duty towing package brings towing just over 13000 lbs with the corresponding hit to your mileage.
13k is way too much weight for that engine. I was towing 7500 and losing speed up hills.
@down_yonderthe majority of theses trucks have that gearing which works just fine with the 10 speed transmission
@@cstgx13000 is only if you have the max tow package which has lower gears
I havent really noticed much of a hit on my fuel economy with the max tow 3.73's. If I had to drive 80 mph like the city guys do, it might burn more fuel, but cruising at 65 mph I average around 28 to 30 mpg with my all time best being 35 mpg average on very flat terrain during a 50 mile trip. 2024 Silverado LTZ CC 6.5 ft bed with max tow.
@@cstgx To be honest, way to much weight for a 1500.
Great Review… this is def my next truck. All mild concerns addressed. Thank You!
Tim, GM doesn't make the Delco diesel fuel additive anymore. Part #10-1034 has been discontinued. Since GM doesn't recommend any other, what should owners do? Maybe you could ask GM. The owners manual says to use it.
Have the 2020 Silverado love the mpg and tows great. Have had issues with transmission hopefully this recall that just came out corrects this.
I talked to you over email before ordering my 23 Yukon Denali Duramax. 25k miles later no issues. Absolutely love the engine. Great power and torque. Much more lively than our previous gen Yukon with the 5.3. The 6.2 is nice, but lots of lifter issues noted. We are getting 25mpg lifetime mixed driving. Highway as high as 31. Around town 24-27mpg. Such a nice powertrain. I do use EDT additive at every fillup.. I figure it can’t hurt. I hope GM keeps making the 3.0. My next SUV will more likely be the z71 suburban Duramax. Thanks for the great diesel content.
Well im 3 weeks in w this eng in a 24 rst silversdo beyond impressed !!!!
Check the oil for the first ten thousand miles, mine drank an extra qt the first two oil changes. At 20,000 miles with zero issues. Pulls like a mule and sips fuel. It also starts great in negative temps.
I own a 2020 Sierra with this engine. It's awesome! I have 70,000 miles on it. Maintenance is simple. Oil changes, DEF, tires etc. No appreciable differences in terms of cost over my previous gas engine vehicle. In warmer weather I get 30mpg in the highway. I could not be happier. I had a diesel vehicle in the 1980's. It was prone to fuel jelling in cold weather and it smelled. This Duramax has none of those issues.
I would caution people to avoid 2019-21 trucks with 100k+ miles or negotiate price carefully. Those years tend to have more issues with timing chain wear. It's an expensive repair (approx 40 hours of labor). Some guys dont have the issue, others bought a used truck with 100k miles and eventually get the CEL code due to timing chain wear. Newer trucks with high mileage dont seem to have the issue, so they either changed the tensioner to put less stress on the chain or they improved the chain itself.
Great video! I agree with everything you say. I have 24 ZR2 3.0L. I use it for work in ag consulting business. I had a 2023 ZR2 with 6.2L. I averaged 15 MPG with a little over 300 mile range. Had to use 93 octane. Now I average 22 MPG with 500 mile range. Diesel is $0.30- $0.40 cheaper than 93 octane in TX. I use 1 gal DEF per 800 miles. No big deal. I change oil at 5K and it’s down a quart. If I had to add a quart no big deal. I drive 50% off road, idle a lot with AC on in 90-105F heat. No issues through 12K miles. This truck gets me anywhere in any condition; mud, sand, snow, pivot tracks. Oil change is about $30 more than 6.2L. And I’ll trade it off before 200K!
I really like my 2023 1500 Silverado 3.0 diesel. Wonderful engine.
I have a 60mile one way commute to work. I think i have found a sweet spot with this 3.0 (mine is LM2) with my usage. I get 30mph on average and have refilled DEF at a truckstop from the pump twice in about 15k miles so far. Actually measuring my usage on this tank of DEF. I have yet to tow, so no data on that.
Love my LM2...had it now 60k km and have only had oil changes and put DEF in every 5-6k km. Crazy good mileage. Only downside I have so far is the higher price of oil changes (roughly double).
I have had my 3.0L in my Trail boss for almost a year. MPG is awesome and it do tow fairly well. one of the Best engine out there in any vehicle.
I have this engine in my 2024 Sierra SLT. It is an absolutely amazing engine. I drove from Alaska to southern Arizona a few weeks ago and fuel mileage was amazing. I topped off before leaving Alaska and I needed only three fill ups to get through Canada. Another three fill ups in the Lower 48 got me all the way to my destination southern Arizona and I still had half a tank left. I can't say enough good things about this truck and its engine. I loved the 6.2L in my 2019 Silverado, but it just doesn't compare to my 3.0L.
I have a 2022 Suburban with the 3.0 duramax. 50k miles on it and not a single issue. Routinely get 20 city and 25 highway. And lately diesel fuel is cheaper than super unleaded. No regrets at all.
Very interesting! My experience with most diesels are they can “gel” with cold weather? I presume plugging them in prevents this? Also cost benefit vs gasoline engine? Diesel is more expensive! I live in Montana and grew up in South Dakota! So I’m hesitant with diesel and turbos!
I have 5k on a 5/24 Sierra 1500 SLE. Best driving vehicle I have used. It would be very useful to have an indication of regen built in as you could then make the decision to finish before shutting it off. Without the iDash you would never know. Yes it picks up seamlessly after shutdown or long idling. Also a DTE for DEF would be nice. After pulling high drag enclosed trailer DEF DTE went to 125 miles while pulling then back to 1213 after no pulling it with a startup popup EVERY time until added 2 gallons. For that matter, a service menu BUILT in to nearly eliminate any need for scan tools.
I have a 2020 Sierra with the 3.0 and love it. Great fuel economy and with it mated with the 10 speed the power is very linear feeling. Pulling my 5500 camper it is always in the right gear.
Great summery!! Thanks for the comments.
Very good video, Tim.
Almost bought a GMC Sierra Denali with the LZ0, but in 2022 GM was missing too many options on them due to the chip and parts shortages. Ultimately went with the Tundra. Love it, but the engine recall sucks.
So looking at the chevy 150o with the 3.0 vs ford 3,.5 powerboost. As a daily driver. Which one will be better for someone who doesn't drive very much but wants the best fuel economy?
I love this in my Sierra and was hoping to get my wife a 3.0 in a 2025 Yukon Denali Ultimate…but GMC isn’t offering it in the top trim next year. A huge mistake IMO.
Alright so I have some questions. In terms of cost: How does it compare to the turbomax 4 cylinder? Horsepower and torque seem similar? Here in Ohio diesel typically runs $0.50 over 87 octane gas. Based on 25000 miles per year numbers look pretty close. Which is more reliable? Would you buy a used one? I am looking for bang for the buck
Thoughts on cost of maintenance and the reliability of a Sequoia 4wd 2025 vs tahoe/yukon AT4 w 3.0L diesel, daily driver, family hauler??
Excellent video! I have a Chevy 2500 ZR2 with the 6.6L diesel and love it. My wife is going to be getting an SUV or GMC 1500 AT4 with the 3.0
never bought a american vehicle but watching your video, and having the need for a truck that can tow my small camper and be a commute vehicle the 3.0 was a no brainer
I have a 2021 GMC 1500 AT4 with a Duramax and use it for work so it has 115,000 miles on it. Just like a two thousand miles of that towing. I beat it up but make sure it is maintenanced and taken care of that way. I have not had a problem with it and I have never heard it regen. The dealership had to put in a new glow plug and they paid for it. Also had a weird steering thing happen to it but that went away. And that is it. I live in South Dakota so when it gets down to single digits and below zero I plug it in and it never has problems starting. It is a really good truck and when I get it paid off I would like to get the same one but a Denali and use that for my non-work trips!
I came from your other video but thank you for this video too. I'm new to learning about cars but I've watched many car enthusiasts like Joe Raiti, Sofyan, and Doug's videos regarding the duramax engines in the Tahoes being really good but never understood the DEF system, regen, etc. Thanks for going into more detail, this makes me feel comfortable about buying the duramax engine option. The mpg's are much better on this option which I love, but I do know it's much more maintenance than the 5.3L or 6.2L options. Diesel is not that bad either, I'm in California and at the shell gas station it's $3.05 right now which is better than the $4.29 I filled up at today lol.
You hit on the major question about the economics of owning a diesel vehicle. There is a WIDE disparity between diesel fuel and gasoline fuel costs by area. Where I live, diesel fuel is MUCH more expensive than gasoline currently, up to 40% more expensive than gasoline per gallon at some stations. The blows the fuel cost advantage of the diesel pickup out of the water compared to gasoline powered pickups, even though the gasoline pickups get lower fuel economy. Interestingly, diesel fuel is much more costly where I live because it is a farming area with very high diesel fuel demand for both farming and trucking.
Diesel near my home~ 60 cents/gal more than reg (87) gas. 50 miles away and different state near my workplace, diesel is up to 30 cents more than reg. Gas but the same price as reg near my home. My state has fairly high taxes on diesel vs gas. In my 25 years of diesel ownership, I’ve seen it 50 cents or so less than reg and $1.50 or more higher than gas. On the plus side, local stations don’t “usually” jack the price up every Thursday on diesel.
@@rockymountainjazzfan1822 Wow. Thanks for the feedback. Which truck do you think is better to own gas or diesel? Or it is based on your lifestyle and how you plan to use the vehicle?
@@jeffs2809 Interesting. I know prices will vary depending on where you live out so I was surprised to see that it was cheaper in my area, considering i'm in California. Do local stations also sell Top Tier Diesel?
@@koharu.mochii I have no top tier diesel anywhere nearby. Several top tier gas pumps but none of them carry top tier diesel. I have one station that carries a "premium diesel", but the US doesn't really have a standard for what that is. They claim a higher cetane and additive package & I've never had an issue with their fuel. It's always about the same price as the other stations in that area. Around $3.59 a week or 2 ago. Stations near my office are around $3-$3.20.
Auto start stop eliminator shouldn’t be used based on the idling recommendation?
It’s fine. Just not great to let it idle for hours on end. Not great for the emissions system.
My 2022 Tahoe RST duramax has been awesome. 42,000 trouble free miles. Lots of city driving. Around 7,500 miles out of a tank of DEF.
Get ready for your coolant control flow valve to fail. Do yourself a favor and order that part now. Mine failed at 45k miles and many many others have too. 3-5month wait time for the replacement part. I have a70k dollar paperweight until sometime in February.
One correction on the idling & regen. The Ford f-350 I drive at work will go into regen at idle and has many times. The engine speed increases & it does its thing. It definitely takes longer than a driving regen, but still gets it done. From memory, I believe Ram will also do parked regens, but I don’t know for certain when that strategy was implemented.
I have a 2020 Sierra with 52K. First diesel I have ever owned and wouldn't consider any other engine on my next vehicle. This thing has great fuel mileage and plenty power for towing.
At what mileage do I need to service my trans? 10spd... 3.0 duramax
I have 23 Silverado rst 3.0 no problems when lease up will get another one . Want Silverado with more options great video will subscribe Tim
Same here. I just got a loaded up LT Trail Boss midnight edition coming out of an RST.. absolutely love this truck and the 3.0 with the 10 speed trans is the best!
Have a 23 trail boss with the LZ0. My first diesel as well. Have done two oil changes on it already with then 5,800 miles on it. I’m already at 80% and haven’t put a thousand miles since last oil change. Any input greatly appreciated. Been subscribed to this channel for a while.
Are you towing a lot?
@@Pickuptrucktalkthanks for response Tim. I have only towed once with it to be honest. Love the truck but can’t understand the oil situation. Dealer told me it’s a very thin oil they use and is calculated on how many starts etc I do on a daily basis. Could not find a number for GM Tech support direct. I have my 2012 Tundra I’ve been using for towing a 14’ tandem trailer. Own a kitchen cabinet business and use trailers versus box trucks for deliveries which was the main purpose of buying a diesel. Looking to trade Tundra and wife’s 2008 4Runner in to get something newer for her.
@ all automakers are using thin oils. Nothing new there and doesn’t affect intervals. How you use the truck really matters for oil life.
@@Pickuptrucktalk using it as a daily driver for the most part a lot of stop and go a few miles here and there. Some highway driving but mostly small town driving.
