- A quick video on some PROs/CONs we have found while owing our Chevrolet Silverado 3.0L DURAMAX over the course of 6 months. Bottom line, we have been incredibly happy with the truck and it has suited our needs well, however it does have some CONs.
In the next video, we will take a look at the truck and if its sustainable in the extreme cold and sub-arctic conditions.

Super informative, great video thanks
Thank you for the great information..
I have the same truck and engine. Almost at 60k miles and it’s been flawless. I’ve had a pulsar on it for a while, which only increased the performance and drivability. It’s a great truck, it will stay with me.
My 21 AT4 gets 9-12 heavy towing 7500 lbs. The PPE intercooler was a nice addition but didn’t help with Mileage.
Did a full weight reduction on a Ecodiesel, I mean everything, mind blowing transformation, fuel milage through the roof, throttle response is violent and the best part the engine oil stays clean incredibly longer. No more empty plastic DEF jugs, no more codes.
We're still waiting for those kits to be available for the Lm2. Probably mid summer early fall since full tunes are available. I wouldn't be surprised if I got close to 40 on the highway with mine. I still range 22-26 hand calculated at the pump with 4" lift, 35's on beadlocks and 2" spacers mostly stock. Only thing I replaced was that baffled air intake with a 3" aluminum intake, stock box.
Diesels warm up best under load. Start it, idle it for about 5 minutes, and drive off with a light load on the engine 👍
100% Aggree with that! Once we get moving it warms up super quick. I was really hoping it would kick into an elevated idle like the 6.6L but I havent seen or heard higher RPMs during autostart. I'd expect it to kick on after a few minutes, I'm doing more research into it as well. Learned a lot recently. It does kick into some special Cold Weather mode when its down to -30ish Farenheit. Waiting to get temperatures like it again here soon, hopefully able to capture it on video.
The 3.0 liter doesn’t have any kind of a high idle. That comes from a engineer who built that truck.
Not these
What’s the regen you talk of?
🤣🤣🤣 let me guess you live in the city in a warmer climate? Problem with diesel engines is guys like you owning them who dont know shit about diesel ownership lmfao. Might as well wear ur hat sideways.
Nice video. I have a 2020 Chevrolet Silverado 1500 LT with the 3.0 Duramax and it has almost 90k miles on it.. We live in Maryland and average about 27MPG. My truck uses about 6 gallons of DEF over 7500 miles. Try getting a Banks Pedal Monster with the iDash. S&B makes an awesome cold air intake. Combine that the PPE new intercooler. We have towed 8500lbs and the truck was getting around 17MPG. Banks is hoping to have the Derringer out by this summer. I am planning on getting one to help increase the horse power to weight ratio.
I installed the S&B, and you can hear an audible difference, although power feels about the same. We will shoot for the 8500-9000 lbs range in a few months + payload; excited to see that, and how the truck handles, 15-17mpg would be nice pulling that kind of weight for 4k miles, haha
I pull about the same weight travel trailer and my 2021 sips def. I actually took it back to the dealer to test the def system because I saw others complain about the heavy def consumption.
Great truck I have a 21 AT4 with the 3.0 Diesel and keep getting the crank no start condition and I don't like the way the 10 speed shifts and downshifts.
I'm considering replacing my 2019 2.8 4x4 Colorado111'000 miles with a 23 Custom trail boss 3.0. I've read and watched a ton of positive on the 3.o engine but I'll miss the maneuverability of the smaller truck.
Very true, I came from a Jeep Rubicon....I understand that. This truck does have more room for activites and comfort inside. A big bonus on my end.
Questions, 1. Are you using the block heater? 2. Did you pay the sticker price? Will you lose your warranty if you install after market parts? Thank you for going over your aftermarket parts AFTER YOUR REVIEW of the truck!!!!
Hey there! I appreciate the questions and watching my video! So for your first questions, YES I will always use the OEM block heater that comes with the truck or any vehicle during those cold nights and the additonal heating pads certainly help when temps drop below -20F. For the warranty, no it will not void the warranty. It is a very common practice in the aftermarket world, some dealers install a $900 "Winterization Package" on new vehicles before they are sold that include heating pags, trickle charger, battery blanket etc. Look into the Magnuson Moss Warranty Act, this is the legal-side of how aftermarket parts will void or not void your warranty.
Under light duty driving I made my first DEF fill at 7000 miles and it wasn't empty yet. Only took 4 gallons
2021 model year
That's amazing! About the same here. We towed about 4k lbs this weekend and went through half a tank in about 450 miles, what a time haha
Good video. Is it an LM02 or an LZ0? I have a Colorado with the 2.8, once I hit 200k I’m probably going to upgrade to one of these. My advice from having a mini diesel
- I always use a fuel additive (Hotshots EDT)
- Get diesel from a place with a good turn over of fuel, I go to places that are busy and a lot of commercial vehicles use
- If not towing, I try and keep the DEF in my take about half, to avoid it going bad from just sitting in there. I go through 2.5 gallons of def every 3-4K. NEVER use the Peak Platinum in our trucks, it will put it into limp mode.
- I have a Provent 200 catch can, to keep the intake and turbo clean. For you being the cold weather, I would be careful if you get one because the cold will create a lot of moisture and it can freeze, resulting in the crank case over pressurizing. The Provent had a relief valve built in to prevent this, so if you do get one I would 100% not get any other.
Good luck with the truck, I’m sure it will last a long time if you take care of it.
Lz0 is new for 23. It's a lm2
@@cstgx Spot on Greg! I am jealous, those LZ0s are really nice and have considered upgrading a couple times. I was going to give it a little bit to see if any kinks were found. I don't like to purchase the first year of anything.
Much appreciated BPF, thats incredibly smart about the fuel. I also try to run "TOP TIER" in all of my vehicles. I almost purchased Peak Platinum, at Autozone the other day...close call. Loving the LM2 thus far, the LZ0 numbers are really nice but for what I am towing this suites my needs perfectly. Knock on wood...haven't had any emission issues thus far.
@@CHASING_BUILDS I would get Top Tier Fuel, but there’s no stations any where near me.
Ran Peak Platinum often and zero issues in 12k miles. DEF consumption reduces uses Platinum for some reason???
If you're going through def fluid it's definitely going through regen then. I've got 2500 6.6 Duramax it doesn't tell me it's regening I just know it idles higher and you can smell it and obviously exhaust is a lot hotter and engine compartment. Far as ik that's really only time mine uses def fluid or it doesn't hardly use any until it goes through a regen.
Andy, for sure! That is what I hope; on the 3.0L pages, they indicate that it typically notifies the driver, but I haven't noticed and expect on our long pulls that it would exploit that opportunity.
Alaska is defiantly the testing ground. 4 years at Eielson... Looking at 2023 for towing a bass boat in the lower 48.
The LZ0s are absolutely beasts from what I hear!
Two things. You have gone through a regen. They on average go about every 400 miles when new. And less infrequent as you go. You probably just haven’t known that it was in regen. It doesn’t tell you. Some key signs are. Sudden drop in mileage and miles for tank to empty. And there is a slight smell. Mine just went through one. There is a guy on youtube who is datalogging Demonworks is the channel. And on my truck. The diesel was just a $995 option. Over the stock. The 5.3 was a $1200 option over stock.
I have been following Demonworks for some time and love the channel. Just got done watching his latest on the regen. Going to get myself the IDASH here soon. Have a couple things in the works at the moment. Might try to also snag a programmer once those get released...
Did you add the towing mirrors? If so, what was the cost of that option?
They came stock from factory on the truck. Love them for towing!
Something is wrong on DEF consumption. I have a 2020 LM2. YES, ALL DIESEL engines drink DEF when towing. EVERY BRAND THEY ALL DO. NONE is even close to drinking 5 gallons in 700 miles. I hope your inaccurate. If not you need to have truck looked at. I tow all the time. That consumption rate is insane.
Norman, I hate to say it, but we topped off the DEF before our trip last weekend and went through half a tank of it after ~380 miles towing our 24' empty enclosed trailer, which is about 3500 lbs dry. Insane right. The truck is going into the shop in February for another issue (I'll discuss it in the next video), but I'll have them look at the DEF consumption.
@@CHASING_BUILDS do you notice a difference in DEF consumption using different blends of biodiesel? Also the propel renewable seems to decrease DEF consumption but i'm coming from a BMW v6 diesel looking forward to getting myself one of these trucks.
17,000 miles without a regen? Did I understand that correctly?
So actually; I learned that it doesnt actually notify you like I thought it would. It actually regened twice atleast from what I could tell from the smell during our most recent roadtrip. Which I think is great, doesnt hinder the user. Demonworks who does several 3.0L videos actually posted a video on REGEN, learned a lot.
@@CHASING_BUILDS It will regen about every 500 miles under normal driving. More when towing. And no, it does not notify you.
With diesel prices? I cannot make the math make sense. Just MGP cost vs gas alternatives
In my situation, owning a diesel works for us. On the highway and unloaded, the price per mile on gas is phenomenal! Gas makes sense when comparing the 5.3L, for example. Doing quick math for our area at the same gas station (Gas $0.15 per mi) / (Diesel $0.17 per mi). However, I spent a significant amount of time at idle; as such, I was going through fuel faster than with my diesel. Diesel engines have better-idling characteristics than gasoline engines and can idle much longer on the same amount of fuel. Another part of my justification was fuel consumption when towing. My 3.0L mileage hovers around 16mpg when towing, while my 5.3L hovers between 8-9mpg with a similar load. Generally, I fill up less often with Diesel, and I've found it to be an overall better experience. I have to also consider the purchase of DEF. Lots of valid view points on both ends.
Diesel version doesn't have lifter issues like gas GM engine. That was reason enough for me to go diesel in our suburban.
The LZ0 is now a $2500 option 😮
4190.00 upgrade in canada if your going from the 2.7l turbomax
Every diesel truck when you're towing goes through def like crazy. I hauled R VS for a living and I drive a semi they all do it.
Just wait on maintenance until you have to change the timing belt. It’s between the Engine and transmission. Therefore it’s a complete engine. That’s going to cost $$$ to do.
The trans gets dropped… It’s not an engine. The belt is rated for 150k miles. Your ignorance is staggering…
Chris, much apprectiate the input! Yeah that will be a headache when I cross that bridge. We will need to drop the transmission to replace the variable valve oil pump belt here in about 10 years. The belt is located at the back of the crankcase. Yeah, not the best design. But that will be something I wont have to worry about for awhile. I did want to ad that GM is confident enough about the new LZ0 Duramax engine’s reliability that it has extended its recommended inspection to 200,000 miles for the Oil Pump Belt.
G
By the time that belt needs replaced, the timing chains and guides will need to be replaced anyway. The belt actually may outlast the chains, they rarely last past 200k. And no, it’s not an “Engine”. It’s a day’s work. Doing them on the front is a pain as well. I would have liked to see it all be gear drive, but beggars can’t be choosers I guess.
Everyone talks about the changing of the belt at 150-200k. Chances are the transmission will give out before the belt, so you can just change the belt when putting in a new transmission 🙂
Nice review but your truck has regened a pile of times. Probably close to once every other tank of diesel.
I sure hope so; just something I haven't noticed when driving.
Facts
@@CHASING_BUILDS loss in mileage suddenly and a slight smell.
Deep pans waste of $. Add a filter sandwich adapter and an extra oil cooler, and add elec fans instead for the trans cooler and oil cooler
Smart Idea, changed my mind on the deep pan after what I've heard from others too. Focusing on other parts now.
@@CHASING_BUILDS there is a video on Banks website with Banks himself speaking about deeper pans being useless. I forgot which vid it is. If you wanna get very elaborate but very effective, add an entirely separate coolant loop with its own radiator and electric pump, thermostat maybe. Flow that coolant through liquid to liquid plate heat exchanger(s) with the oil and trans fluid.
jesus 17k in 6 months , mine is almost 1 year 3k miles LOL
Hasn’t had a regen in 6 months? You’ve had at least probably 15 lol
Trent, it has yet to tell me; it's likely done it during our long pulls. Just something I haven't noticed, which is a great thing!
@@CHASING_BUILDS the new engines don't tell you (both the Lm2 and LZ0) it's all done in the background
@@jemery3, I just learned that; it's super awesome. Great feature!
The truck was so under powered it was heart breaking a year into it we ended up pulling the motor out baby gas burner and put back a 6.2 super charged and a transmission charge as well . Now this truck is what it should be pulls my camper so much better.
Must have been something wrong with your diesel. The 3.0 has about the same torque as 6.2 and available at low RPM. Diesels always tow better than gassers.
What are you talking about. You didn’t pull the diesel out and put in a 6.2. Do you know how impossible it would be to get the trucks systems to work. These new Gm’s have so many control modules. Your infotainment system wouldn’t even work.
You are not lying, I was confused by that comment too. I'd need to see a video on it to beleive it! These trucks are locked.
my lz0 region every 150 miles 🤨
Mine didn't regen well during the cold, the DEF tank actually froze..... causing lots of issues.
@@CHASING_BUILDS what is the solution? Use additive like hotshots?
@@watchmanexpert Leave it parked in a heated garage is how I was avoiding the issues. The truck does have heated DEF lines which is nice if you are traveling but at some point, it will freeze over if left outside. My entire DEF tank had to be replaced when it essentially exploded at the top due to freezing/expanding.
