6 Months Later... 2023 Chevrolet Silverado 1500 3.0L Duramax Review

[@platypuspizza4779]

I have a 21 Silverado RST, 3 L diesel I LOVE it! It’s smooth, it’s sweet, it’s comfortable, it gets great mileage . I’ve made two trips from Omaha Nebraska to North Carolina, hauling trailers. One with the 16 foot covered trailer, the other, wish an open car carrier, with a 2005 full-size Buick, LeSabre. Going to the mountains of Tennessee and North Carolina, I did not even know that trailer was behind me. The tow/haul mode on this truck is incredible!!!

[@Thomass7878]

My best 450 miles is 42.7. My average is 32-33 mpg and my typical month I fuel up once a month. Love this truck!!! Highly recommended if you don’t tow/haul anything super heavy.

[@andrewflores2125]

I’ve recently purchased a used 2021 Sierra SLT X31 with the 3.0L diesel engine. Truck has 85000 miles on it now. Fuel mileage is great getting 22 - 38 mpg. Has awesome torque and power. I’ve not noticed any real excess oil usage. If you have ever owned a vehicle with a diesel engine they will use oil. If you allow your engine to idle for long periods of time it will use more oil. This truck has more options on it than I will ever need. Electric everything even the parking brake. Heated and air condition seats and very comfortable for king trips. I hope all of you come to enjoy this truck.

[@craigwilliams1073]

I've had the 22 a little over a month, and wow! Due to my father having dementia, I've had to make several trips from Maryland to Detroit Michigan! I never need to stop for fuel or DEF. I just had the first oil change and this truck continues to surprise me. You assessment is 100% on target, thank you for keeping me informed on things I didn't think of. Oh, and the one Month mileage is 6500.

[@Andrew-315zz]

I have a 2022 GMC AT4 3.0 Duramax. Purchased Sept. 2022 and have 8K miles on it. I have to say I am over the moon in love with the truck. I have owned I don't know how may 5.3 gas engine trucks and the 3.0 Duramax blows them out of the water. No question. For me, towing a bass boat and driving back and forth to work, the fuel mileage is outstanding. I live in WV and I consistently get 26-28 mpg back and forth to work. In warmer weather I have seen 30-31 mpg. Towing a full size bass boat from WV to TN the truck produced 22 mpg. No oil usage seen to this point. DEF added one time. Thus far, no complaints. Definitely would buy the truck again. If you do not need a big diesel....I dont think this truck will disappoint.

[@joandublanica4388]

,I have a 2024 Silverado 3 litre Duramax plus a 2022 Ram Eco Diesel .The wife and I like the Ram better.The only thing a little better on the 3 litre Duramax is the mileage.Ram is quieter better ride and more user friendly.I do think the GM Duramax is a more dependable engine then the Eco diesel.

[@impala-wf2sd]

I hit 25k on my 2021 silverado 3.0!!! No mechanical issue thus far. It does not burn oil & def usage is minimal. Averaging 32-33 mpg & i drive 700 miles a week with 1 fillup. Low end torque is amazing . I would recommend this engine to everyone.

[@williamabaker12]

It scares me a little that some people are saying they have no oil burn and some claim to burn a quart or more over 5k mile oil change intervals. It's either designed to burn oil or it's not, right? I get different driving patterns, different usage, etc, but if I were to get one of these, my OCD would drive me nuts if I got one of the burners. Lol

Also fighting strong winds through the Midwest. I now have 11k miles on it and still love it. I also have a complaint about the wireless phone charger bc mine rarely connects to my phone to charge. Rarely have the CarPlay issue also. I was more than pleased by averaging 26mpg during that road-trip driving the truck extremely hard. No issues towing enclosed trailer with 2 snowmobiles up and down a mountain either

Hey Tim, Nice 6 month review on your new truck. Here is a non paid or sponsored idea on your oil availability issue. I use Amsoil synthetic oil and it is delivered to my door within a couple of days ! Yes, they do carry 0-20 for your duramax. The oil is $13.39 qt. Or 10.19 if you sign up with a membership. I have used this oil since “79” after my neighbor ( engineer at Air research aka Garret) recommended it to me after they tested the oil. Amsoil was first developed for fighter jet engines. I’ve never had an engine failure oil related or otherwise. Stow your extra oil bottles in the rear seatback storage compartments! Lastly, try your seat heaters on low or medium to soften the seat cushion as well as your low Back muscles on your trip! Have a great safe road trip! Ron

[@donmckenzie5027]

That’s all I put in my cars and my new 2023 Gmc 1500 Denali LZ0. Amsoil is incredible oil!

[@waynehawkins9090]

Have a LM2 3.0 in my '21 Silverado. Have no issues with oil consumption. Have close to 17,000 miles. Love the truck! Z71 package.

[@keithwarstler9500]

I love my LZO! The mileage is incredible! I had a 2014 RAM Cummins Dually that I pulled a 42’ fiver. Bought a diesel Super C RV and sold the RAM and bought a Jeep Gladiator as a toad. Just wasn’t happy without a pickup so I bought a 2023 Trailboss that I can still flat tow and it gets great mileage! It’s amazing to have a 1/2 ton with that amount of horsepower and torque that I can still haul and tow most of what you need in a weekend basis! Great motor and truck!

[@JeffSpangler-wn9ee]

I have a 2023 LTZ Z71 Duramax; I love it. Bought it new June 1st have just under 6k miles. Live in Florida; getting 31 and 32 mpg on trips. Range of over 700 miles. No issues with oil, but I did buy some on Amazon to have. I got an early oil change at around 5500 miles only because I had to take in for a tire pressure monitor issue. From what I can see so far; my DEF will only need tipped off when I change the oil; used a couple gallons. Love it for all the reasons you commented on!

I'm 4 weeks into owning my 2023 Sierra 1500 At4 LZO and I absolutely love it. Just turned over 1000 miles with 4 longer trips and a bunch of short city trips and am getting 28mpg average and trips with over 31mpg+ on I-90 in eastern WA doing ~74mph. Love the drivetrain and the feel of the diesel.

[@iplaywithtrucks7230]

Do you have mud terrain good year tires or AT's? I have achieved 30mpg before but a recent trip to Florida and back from Midwest I was only able to average 26 with my AT4. That was running cruise religiously and mph in the low 70's. If I run below 69 mph it makes a substantial difference. Thinking of removing the mud terrain tires and going to an AT tire.

[@braddsn]

I have the GMC 1500 with the 3.0. I have had a lot of trucks, mostly with V8's. I feel like I never put fuel in this 3.0. The fuel economy for a full size 4x4, is incredible. And the torque curve is silky smooth and fun! My engine doesn't use a drop of oil. It's weird how yours does. As for where you get your oil, I switched to Amsoil long ago, and I have all of my oil shipped to my door. They have the 0w20, and it has the dexos rating.

[@timgurr1876]

@@braddsnI don’t see why a new truck needs to be using oil. Maybe on the initial break-in but after 2000 miles it should not be using oil. For me, that’s a big hassle to have to worry about oil level. In this day of technology the truck should tell you when it needs oil. I like the chrome look. That’s what I grew up with. Thanks for the review.

It’s 2023 not 1973. We should not be having to add oil to our engines in between oil changes in my opinion. My daily is a 2015 Cummins and it basically uses no oil in between my 7500 mile services.

[@tannergregg4190]

His truck is not truly broken in. It may not use oil at 20k miles.

It's designed to use oil. Your Cummins have 13 quart pans. You'd probably never notice oil usage.

[@kameransnyder9596]

My 3.0 duramax has 98,600 miles. Went in last Friday, possible engine failure. Should know more tomorrow but it has burned oil at a consumption rate of about 1 quart every 5,000 miles since it hit the 30,000 mile mark. Would be happy to share what the diagnosis is when I find out. Genuinely loved this truck, but GM says they will put a new "reman" engine in it if needed. I have heard rumors about crankshaft and something to do with bolts "backing out". Could be the cause of the oil burn, idk

[@rickeycooley9139]

Why,…why did they design it that way ?

[@dimav975]

​@kameransnyder9596 did you find the reason?

[@duggydo]

I think the oil consumption is a class action lawsuit waiting to happen. All it will take is for people to get lazy and stop checking it. The big question is, where is the oil going? Is it on the cylinder walls getting past the rings? That is a fixable problem the engineers should address.

[@khakiswag]

And this lawsuit happy society is one reason everything is so high. Add a little more to the sticker price to cover any possible expense of litigation.

[@radoliz2]

@radoliz2 13 hours ago Oil consumption is happening to those who do not observe the break in period correctly! With 0w-20 oils, fuel dilution of oil takes place rather rapidly. Every time you give it WOT during the first 2,000 miles your adding unburned fuel to the engine oil. If you let the oil level get below add and keep driving it. You ruin the break-in of the rings especially the oil rings. Then you have a oil user the rest of its life. Two quarts low is one quart to many. You should keep a eye on the oil level for the first 5,000 miles at every fill up. It is not caused by the manufacturers. It is caused by the owners, thinking it shouldn't use oil and never keeping a eye on the level. And not observing the break-in period of no full throttle, or holding steady speeds for long periods of time. READ THE MANUAL and practice what it says. Keep the oil topped up, and look for fuel dilution in the engine oil. Sometimes it might be best to get a oil change at 3,000 mile mark to be sure it is not diluted.

[@theodorgiosan2570]

It's low quality oil. The AC Delco/Mobil oils are too thin for the engine. With the Amsoil DP020, people are only getting consumption of 1 qt per 6000 mi or less. Similar could be accomplished with Ravenol LDD 0w-20 which is also a bit thicker, or Liqui-Moly 6610, which while it doesn't meet Dexos D per se, it meets OPEL OV 040 1547 - A20 which is the European spec for the smaller 1.5 and 2.0 engines of the same design. Any oil meeting that spec will meet Dexos D and be superior in viscosity and shear stability. Liqui-Moly 6610 can be ordered at NAPA in 5L jugs. Don't know about the Ravenol yet. I use the Amsoil in 1.6 Cruze diesels after converting them to the LM2 timing chain tensioner. It ends up thicker than the original 5w-30 did after an oil change. And no more tensioner issues. There's a reason they changed the spec to the special 0w-20 on the 1.6 in Europe years after the last one came off the assembly line.

Where we live in Idaho diesel is at mid-grade gas prices. So really the only extra cost to running a diesel is the DEF. Especially when you get a 50% fuel mpg increase vs a half ton gas, you are actually saving money by running this diesel. As for oil changes I always do my own. So 1 to 2 extra quarters....not a big deal when you get all the other benefits of this engine. I've scanned the comments for this vid and numerous others on this truck and most people don't have as much oil consumption as you do Tim. Also seems most people seem to get even a little bit better mpg's. Great vid. I know people who have this truck and they say it would be the last vehicle of their's they would sell. Keep em coming.

[@thomaseynon6205]

So after looking into the oil situation, there are good options. The separation from Oils calling for Dexos D - they have an ACEA C5 approval (which can be found on the newer Mobil 1 Dexos D approved oil). The ACEA C5 standard is a European standard for oils approved in both gas Engines, and light duty diesel engines. Any Walmart location will have 0w-20 oils containing the ECEA C5 standards. They may not identify as Dexos D, but will match the same standards found in the approved Mobil 1 Dexos D. I’ve been using Castrol Edge “Unlock Maximum Performance”, and my truck has been running great. Definitely not wanting to start a debate. We spend good money on these vehicles, and I’d suggest for people to come towards their own conclusions. Just thought I’d share my experience, considering Dexos D is non existent in my area.

Def consumption dropped quite a bit once I passed 4500 miles. I think I am at a total of 9 gallons of DEF for 10k miles and it's currently full.

[@16vjohnny]

DEF consumption is usually pretty linear with fuel consumption. The only explanation for it using less DEF is that the EGR is running at a higher duty cycle to reduce NOx production. Soooo.... driving it very lightly or not towing. Could also be a function of cold outdoor temperatures (or not). That said... the DEF consumption on my 22' really is something I rarely think about. Couple of jugs from Walmart a few times a year.

[@zxej6879]

I really like the new design inline 6 engines that put the catalyst and DPF under the hood. Is going to reduce the thefts quite a bit. Also taking the EGR after the DPF and SCR is a plus. My Ecodiesel days may be numbered. I am debating ordering this truck, a Jeep Gladiator, or a Ram Warlock 3.6L gas for simplicity. Whatever it is, it will possibly be my last new vehicle into retirement. The spec oil is an issue that people would want to know more about. My Ecodiesel uses 5w40 T6 Rotella, never needs oil added in 10k miles between changes. My wife's Cummins does not need oil added between oil changes either, using the same oil. My gas 3.6L Dodge Durango uses no oil in 10k miles between oil changes, using 0w20 oil. If the T6 Rotella can meet all emissions needs. I would run that oil, if I buy the Chevy diesel.

Great review Tim!! I agree with everything you covered. I have a ‘23 LT Trail Boss with the LZ0 and absolutely love it. The only dislike I would add is the windshield wiper control. You can’t just tap a lever to clear the windshield. You have to locate the control on the arm and twist it. I know it’s very minor, but it bugs 😂

The lack of the Mist wiper function on the American trucks is what got me to start using water beading coatings (Rain-X / Aquapel) on my windshields.

I have a 2022 1/2 LTZ with every option. I have averaged 27-30mpg with no issues. I don’t tow anything with mine. Put 6k miles on it, bought it with 6k on it. No oil consumption issues with mine. No issues with my wireless charger as I have a thinner case. Also I have only had to put def in it once so far. So I don’t see that as an issue at all. I just use the ones at the pump to put it in. I drive a F450 for work and know all the places to get it. I love the truck, plenty of power , rides amazing and lots of room.

Nice, to the point, comprehensive short term review. I agree with you that DEF is a no issue but I guess people need something to pick at. With regards to oil consumption I’m also with you and still scratching my head. I’m no diesel expert but I have never had any vehicle that burned or used oil (not even a 1/2 quart) when mechanically sound. Having a service bulletin stating its normal just feels like a CYA for a bit of design or component selection issue. I wonder why my previous GM, Toyota vehicles never used oil even when towing yet this is normal for 3.0????

@@16vjohnny That's it exactly - the 3.0/10spd. I use the truck for work and occasionally to tow my crawler on longer trips (8500 lbs on the trailer). I've got about 30K miles on it since picking it up in July - mostly highway of course. The economy is 100% the selling feature for me. Ford's hybrid has tons of power but I just don't care about 0-60 for a work truck and the hybrid does nothing for highway economy so I wouldn't even see much of a payback there. The Lightning? Forget it - It's miles from meeting my needs and doesn't even come in a work truck platform; just the kid-hauler max-cab/min-bed setup. Over-all I've been pretty happy with the truck though I'm starting to have some transmission issues I need to get sorted. There's a GM campaign on that specifically so hopefully they won't just me the 'they all do that' or 'couldn't duplicate the problem' bs.

I agree, DEF isn't that expensive and if you go to the truck stops they usually have DEF at the pump and it's easy peasy to fill then. It isn't that expensive and is required.

Everybody complained about EGR and EVAP in the 90's after OBD II, everybody will find reasons to disagree and complain about any emissions regulations, but I also remember getting gassed out every day in the bus lanes in school from all those idling 6BT's and cat 3208's and nobody wants to go back to those days.

[@GoogleDoesEvil]

​​​@@kodyw2357DEF is way less of an issue than regens on the DPF. I think people don't understand how the emissions system works and thinks DEF is used during regen. EGRs on diesels are also bad but I like that the new LZ0 Duramax uses exhaust gasses after the SCR for its EGR. Should increase the longevity on these engines.

[@logato7128]

Correct me if I am wrong on this particular engine but I would think piston speeds will be lower and expansion higher (more tolerance) so you would expect to see higher rates of oil usage and longer break in periods vs gasoline engines.

Great summary on the truck, Tim! I enjoyed hearing your personal opinions from your list as I have been building a list myself.

The oil consumption issue is very problematic. It will not get better. Other videos have already documented that it only worsens as the engine ages. It's a design problem that should be alarming for any potential owner.

[@theodorgiosan2570]

It's not a design problem, but rather an oil problem. In Europe they have Opel engines based on the exact same design but with less cylinders, a 1.5 3 cylinder and 2.0 4 cylinder. They spec a 0w-20 meeting the OPEL OV 040 1547 - A20 spec. These engines have no issues burning oil, on longer drain intervals, and running high speeds on the Autobahn. This oil also corrects some of the timing chain tensioner issues on the earlier 1.6 CDTI that they are based on. Difference being the oils meeting that Opel spec are much thicker for a 0w-20 than the AC Delco and Mobil Dexos D oils are. Some oils meet Dexos D as well, others don't, only because they don't want to pay the licensing fee for a relatively niche market compared to Opel diesels in Europe. They also tend to have better high temperature characteristics. Another solution is the Amsoil DP020, which is also on the thick side for a 0w-20, and is designed for the 3.0 Duramax. Not certified, but if they analyze it they are not going to be able to tell it's not a Dexos D oil, the viscosity characteristics will line up. A certified but hard to find option is Ravenol LDD 0w-20 which meets both the Opel and Dexos D spec. My oil choices would be: 1. Amsoil DP020, 2. Ravenol LDD 0w-20, 3. Liqui-Moly 6610. Any of those are going to be light years ahead of the AC Delco or Mobil 1.

[@1randyharbin]

I really wonder if the engine was broken in properly, first 500 is not above 55, constant varying of RPM (so no cruise control), all per the manual, and mine uses 0 oil between oil changes. I get a couple full oil changes (14 quarts and 2 filters) shipped to the house from RockAuto for $118.46 (priced out just now), so about $60 and oil change. I have used about 10 gallons of DEF in 16K miles, and this thing is so much fun to drive. I'm wondering if that long trip home, over 55, probably using cruise control so the RPM wasn't being varied much, might have not been good for the engine break in.

[@Pickuptrucktalk]

Maybe. I couldn’t avoid the trip home and how I drove on that trip.

[@hammer-r]

I would agree on break in. I’ve got 2500 miles on mine, easy driving and variable speeds and no oil consumption that I can tell. Still shows overfull. Time will tell, but I’m a firm believer in taking it easy on a new engine until it’s got some miles on it.

[@1randyharbin]

@@Pickuptrucktalk, I certainly understand the situation you were in Tim.

[@1randyharbin]

@@hammer-r, 100% agree, I know you get the best break in by constantly varying RPM and lower RPM for the first 500 (I did 600), I also drove for 45 minutes home and let the engine cool completely before the next heat cycle allowing the expansion, contraction, and the seating of the rings, to happen more slowly over a longer period of time, it really seemed to help in my case to give me great analysis numbers according to Blackstone on my oil analysis reports.

[@hammer-r]

@@1randyharbin in your opinion, when do you think the break in is complete? I’ve been trying to put on as many miles as possible before I trailer an RV out west. I’ve got about another few weeks before I put that truck to the test. I’ll still be as easy as possible, but at 7000 lbs and high altitude it’s gonna be a job for her. As for def, I’ve used about 1 - 1.5 gallons per the dash gage so that’s not an issue. I’m sure it will drink it trailering, but for normal driving, it’s not an issue and at the mileage I’m getting, I couldn’t care less. My only concern is which one to buy and getting the best diesel I can find. Tks for your input. And Tim another great video.

Appreciate your review. I have been considering trying a 3.0 over the 6.2 due to fuel tank sizes on the gm. We own a napa store in Texas and we sell lots of mobil 1 0w-20 dexos. Disappointed to hear your store didn't have any on hand. As for the platinum def vs blue def, its my understanding that platinum has a slightly different blend for longer shelf life.

I have personally ran napa brand blue def in all my trucks, tractors, and equipment for years with zero issues. Cheers!

Just turned 20k this week and think ive bought DEF 4 times. Love the truck have had it 2 years and its been great.

[@ksorsomeplace]

The oil...I wouldn't want to run it 2 quarts low. The viscosity (0W) might be fine, but I don't see how it relates to engine component tolerances? 5W oil is still more resistant to breaking down. I would use the 5W if it was summer, if I was towing regularly, or if I was only taking short trips in stop and go traffic. I think it offer better protection for the engine components under those conditions. As an aside: Nissan recommends 5W-30 in their VC-Turbo, but Infiniti recommends 0W-20! Same engine.
