3.0L Diesel Truck As A Daily Driver? 2024 GMC Sierra 1500 Elevation W/ Duramax 3.0L Diesel Engine!

[@ericgarcia3287]

I have a the older LM2 Diesel engine in my 2021 Sierra 1500 Elevation. I drive about 500 miles a week. 320 miles is my commute and the rest of my millage is from other driving. I get about 520 miles to a tank of diesel and about 25 to 30 miles per gallon. So far I have no issues with this truck. When I first got the truck I got two check engine lights due to programming issues in the exhaust system. Now everything is good to go.

[@Myksgarage]

That's awesome to hear!

[@lukedeatley2520]

I use mine as a daily driver and love the truck. No issues

[@Myksgarage]

Nice!!

[@grizzly8960]

Me too love it 22-24 avg best 32 -

[@bancrofthaughton1325]

I have a 22 highcountry with the 3.0l diesel. It’s fantastic no issues. I’m at 47k miles. Love this truck

[@Myksgarage]

Thanks for sharing!!

[@artbossmedia]

I have a 2020 3.0L AT4 with 83k on it. By far the best powertrain I've owned in my 30 years of buying vehicles. Quiet, ton of torque, and crazy good fuel mileage.

[@Myksgarage]

Nice to hear your feedback!

[@MrKeithJ2]

i daily drive my 2024 LZ0 and absolutely love it. purchased it in august and have just shy of 11k on i already. i tow my 38 ft camper, 7x14 14k dump trailer, and a 28 foot flatbed with side by sides on it regularly and i have absolutely no regrets in buying this truck. 2024 silverado RST redline LZ0 max tow package. it was tough to find, but well worth the search

[@Myksgarage]

Thanks for sharing your experience

[@dwhitegoffe]

I just got a 25 redline rst… your right hard to find

[@budlite8207]

We have a 2021 AT4 Sierra and love it. 33k miles now, mostly short trip like 9 miles daily. Loved it so much my wife bought a Yukon in 2023 with the new motor. Both have been trouble free and the fuel mileage is fantastic. I'm not nice on the throttle and still get 23.5mpg in town. Does like 26 on the highway. On the other hand, my wife in the Yukon thinks its an Indy racer and it never sees less than 80 mph on the freeway. Still gets 30 mpg. Crazy stupid for a 6000 lb rig

[@Myksgarage]

Yeah that's some great fuel mileage!

[@robbpike]

Have been driving my 2022 Sierra 1500 with the 3.0L as a daily for a little over two years. It is a great daily driver. It has towed our boat across Wyoming between Colorado and Bear Lake the last two years, and is so comfortable and pulls great for a half ton. It does drink the DEF pretty quickly when towing, but that is only a minor inconvenience. We also tow with our Suburban, which is the previous generation with the 5.3L. That engine has been reliable in every vehicle we have owned with it, but the 3.0L diesel is a fantastic match up for the half ton truck/suv application.

[@Myksgarage]

Thanks for sharing your experience!!

[@70below]

I have a 2024 Silverado with the LZO and max trailering. Best truck I've ever owned. I drive about 70 miles a day round trip and don't think I've ever got worse than 25mpg combined unless I'm towing a lot. I towed a 7x14 dump trailer with a skid steer, 12.5k total and still got 14mpg.

[@Myksgarage]

That's awesome!

[@davidgroves8049]

I own this truck and engine. got 3,500 miles on it. no issues so far and I use it as my daily driver. I do use a lot more def then he has. I tow with mine and once you tow you use DEF! I do live in the mountians. Going to town is 10 miles each way. I have used about 5 gallons of def so far. I only get 22 MPG as I said I live in the mountians and do tow! I did a 400 miles (no tow) road trip and got 28 MPG on that trip. I have the short bed and it parks like a car! Especially if you get the cameras.

[@Myksgarage]

Thanks for sharing your experience!

[@georgecalderon8846]

2023 rst and I’m getting 29 to 42mpg out of mine and 25 mpg while towing a trailer with a 4 door maverick and camping supplies in the bed, best truck I’ve ever had and first diesel truck I’ve ever had.

[@Myksgarage]

That's some great mileage!!

[@bubba2468]

I’m calling BS on that…

[@michaelsuarez3649]

I use my same exact truck as a daily driver. This is my first truck and man I have 0 complaints. Amazing smooth drive, amazing fuel economy. If you are like me and can get passed the cloth trim seats just buy nice seat covers and it’ll do the job just fine. Highly recommend the vehicle.

[@Myksgarage]

Nice to hear your thoughts!!

[@jetfixer3207]

I had a '21 Sierra AT4 with the LM2 Duramax. GREAT engine. (I'm currently waiting to order my '25 Yukon AT4 LZ0 Duramax) 2 items though, #1 if you live somewhere (like I do) where the winters get cold, make sure you have heated seats and steering wheel. To make the engine most efficient, it first focuses on getting itself fully warmed up, so you may wait a "while" before you get any real heat in the cabin. (You're not supposed to use the block heater unless the truck sits out in zero degree or colder weather) #2 full transparency, everybody focuses on that 200K oil pump belt, however the high pressure fuel injection pump is only expected to go ONE hundred thousand...

[@Myksgarage]

Thanks for sharing your insights, I wasn't aware of the high-pressure fuel pump short life

[@jetfixer3207]

That high pressure injection pump lifespan could be taken with a grain of salt. Widely varying estimates on this. Some say 100k, but others say if you keep the fuel filter clean and use quality diesel it could outlast the engine. like so many other things, you'll probably get out of it what you put into it. You hear guys say Toyota and Honda engines will go a million miles. Yeah, well not if you don't take care of it! Same here.

[@davidporter7051]

I have a 23 Silverado with 55K miles averaging nearly 27 miles per gallon. The only additional maintenance over a gasser is the DEF about 5 gallons each oil change and a fuel filter change once a year.

[@Myksgarage]

Nice to hear!!

[@Kookaburra4509]

I’ve got a 24 AT4 with Duramax…only had for 6 weeks so far. Got about 620 miles on the first tank. Drove about 150 miles one way and was getting 27mpg with cruise set at 75. I have tonneau cover and I wasn’t towing. Total about 1200 miles right now and average mileage from purchase is 25.3 so far. Love everything about it except an issue unrelated to the engine. The backup camera on the GMC sucks at night. Not sure why it so bad but a lot of forums are complaining. That’s the only issue I’ve found but I love it

[@Myksgarage]

Thanks for sharing!!

[@Namastayyy]

Just bought a 2025 Silverado RST with the LZ0 and coming from gas powered vehicles to diesel, the learning curve isn’t too bad and I love the mileage. Power is just enough to get you to the speed you want faster then many cars on the roads. Overall it’s been a dream to own so far

[@Myksgarage]

Good feedback, thanks for sharing!

[@Carolinaking22]

I’m buying a GMC AT4 and I’ve been debating which motor to get and as of right now I’m leaning towards the 3.0. Ive always had the 5.3 or the 6.2 so I’ve had a lot of questions about it. Great video definitely helped.

[@Myksgarage]

Glad it helped!

[@na2305]

Thank you so much for making this video to respond to my question. A local dealer wasn't giving me much details on this and I couldnt find it on KZbin. Those quirks are not too to bad to deal with. I guess in the end I just want my wife to jump in and go like normal. I'd be in the dog house if she had to wait and wait to fire it up just to go grab a Starbucks or go to mall. (I'll take care of the quirk stuff). Yes, it can get very cold in North East OH (low teens - zero). We typically put 20-25k miles (mostly higheay) per year on our vehicle so the amazing mps's this diesel woyld get to use as our daily rriver seems likr a great way to go. Thank you again!!

[@Myksgarage]

I'm glad this was helpful! Get one of these 3.0L diesel trucks, you won't regret it! Best of luck!

[@jeffreymaxwell7828]

So does the truck tell you when it's regening?

[@dalelangehennig161]

Super great overview of the things to consider on one of these diesels. But yes, the 3.0 LZ0 + 10 speed is my absolute favorite power train in any truck I have ever owned. I had a 23 and traded for a 6.2 after watching too many KZbin videos about the def, oil leaks etc. I kick myself daily for the trade. The 3.0 was my favorite motor ever. We have it in my wife's Yukon. I will get into another one as soon as finances make sense to do so.

[@Myksgarage]

Thanks for sharing your experience!!

[@raultv760]

I have the same exact truck, the same color too. Truly enjoy driving it to work so far 👍🏻

[@Myksgarage]

Yeah the color is awesome!

[@jakeTHEANIMALgreenarmwrestling]

Best looking truck on the road

[@Myksgarage]

Yeah it looks nice!!

[@josephharvey5742]

I have a 2021 GMC Sierra truck with this engine and have had only one instance where I took it into the shop. From the factory there is a plug that goes to the DEF tank that wasn't snapped together properly at the factory and came apart. The dealer removed the DEF tank and fixed the plug and I haven't had another problem since then. I have about 26,000 miles on mine and would buy it again.

[@Myksgarage]

Thanks for sharing your experience!

[@EReed-qg8lt]

Good stuff. I have a 2023 LZO. Its been nothing but good. I did change some parts though. Trans temp runs a little high for me. I put a bigger pan, a trans bypass vavle and a bigger trans cooler. Change to amsoil synthetic. Temp drop from 198 ish to now 100 to 150 and thats towing my boat. I might drive it 2 days a week or when towing. Then installed the banks pedal monster and that took the pedal lag away. Install response

[@Myksgarage]

Those are some great upgrades!! Thanks for sharing!

[@BloodiedYetUnbowed]

It really annoys me when people start slamming the oil pump belt. I really don’t care about a USD 1,200 maintenance at 200k miles. Like you said, you’ll probably need to get transmission work done by 200k miles anyway, so just swap the belt out at that time.

[@Myksgarage]

Yeah I hear ya!!

[@Reinbold1500]

2023 LZ0 owner here in Colorado. As far as half ton towing goes up here in the high country, this truck is AS GOOD as it gets. It has phenomenal towing performance at altitude compared to any gas engine in any half ton segment. Around town, daily driving is decent. Fuel milage is fantastic, but these diesel emissions systems hate prolonged city driving over time. Whe shall see about long term reliability.

[@Myksgarage]

Nice to hear!

[@nowayoutstp4]

8200 miles on my 24 Tb w/3 liter. Averaging 26 total and routinely get 35mpg. I’ve found sustained 53mph I’ll get 38mpg, 60mph I get 30mpg, 70 I get 25mpg, 80 I get 20….. so yeah, I drive slow 😂 probably the best engine I’ve had. I have videos and also own the 2019 5.3 and 2022 6.6D

Thanks for sharing your your experience!!

[@EdKrzeminski]

I have a 2020 Sierra LT crew cab with over 76,000. If buy a new truck it will be with the 3.0. Life time average is 26.6 MPG. I really enjoy the truck.

[@Myksgarage]

That's awesome!

[@1micYT]

I have this same truck, color and all. Just not the 6 seater and I love it. I get 28mpg. it sips DEF so slowly you hardly ever have to top it.

[@jeffelder3583]

get a banks idash or a cts3 to monitor your soot level and regen.. u can also force regen when your getting close to its cycle

[@Doc_Rom]

How do you force a regen? Would be nice to have control

[@Myksgarage]

That's cool

[@NickBondar12]

@@Doc_Romgo to diagnostics in the idash and then “enable mobile regen”. Key is you need to tell the idash in the settings that you have this specific engine. Don’t remember how but it wasn’t hard to find. After that, diagnostics and then enable mobile regen.

Great review. Thank you

[@Myksgarage]

Thank you for watching!

[@caseyrolfe72]

2024 AT4X AEV here. Just passed 10k and love it. My mpg is a little less but its because its a tank literally! Sometimes i have an occasional hard shift but nothing concerning. My truck even states a little less mpg because of the build but i need it for my job. I still get over 525 a tank for 24 gallons. I use a little more DEF as well but tow a camper occasionally and have had it in some nasty mud a couple of times. I laugh when people bitch about DEF usage. Well you should have bought a gasser then lol. I do recommend the PPE Premium High Efficiency Engine Oil Filter 19-24 GM 3.0L Duramax 1500 LM2 and LZ0. Thats all ill use! They are more but its cheap insurance for a diesel. They come with a magnet in the bottom to catch metal and they filter way better. Theyre about a third longer. Why put a gas filter on a diesel. Look into them. Hope this helps

[@Myksgarage]

Nice to hear your experience, thanks for sharing!!

[@nephron0]

24. At4 with duramax3.0: 33k miles fuel injector issues. Rental for past wk. traction control went out with emissions control problems. Hope it is fixed now…..

[@Myksgarage]

That's frustrating

[@RichardCarlson-k7w]

1 have a 24 AT4. 10,000 km and me thrust bearing in engine crank let go and engine /turbo needed to be replaced. Not happy ! realize not common. But been in a rental for 7 weeks now. Engine was easy for dealer to get 3 week, turbo is harder to get. Actually just came in and expect to get my truck back next couple days. I did really like the truck until the bearing issue . Now we will see.

[@Myksgarage]

That's frustrating!!

[@RichardCarlson-k7w]

For sure as I own a resort and rely on truck. However my rental is a 24 chev 4 cylinder turbo and I like it also.

I have the elevation it drives better than the Denali. Smoother.

[@Myksgarage]

Yeah, nice!!

[@malarie11]

-17C is avg temperature up here in canada. guess id need a bloc heater

[@jmotanks8960]

Can you add a exhaust like a gas engine, like flow master or something similar?

[@Myksgarage]

Yeah you could add an exhaust

[@wayneperry965]

I refill my DEF tank at truck stops every 3-6 months. That way you know it's not old and crystallized.

[@Myksgarage]

That's a good idea!

I am looking at buying a used 2023 denali duramax ot 2023 at4 duramax .. just not able to make up my mind .. i dont off road and want a dailly driver ..i do want the hud and the luxury feel with running boards .. whats ur take on a at4 or denali .. which one would u folks recommend?

[@Myksgarage]

I would personally go Denali

After warranty better ditch them though due to emissions. Expensive to fix.

[@andrewcline4226]

What kind of issues with emissions?

[@jirandakamara1672]

I bought a 2024 chevy tahoe 3.0 L duramax brand new in September, I have only filled it up 3 times and have had the check engine light go on at all incidences (Emission System) took it dealership they are saying its contaminated fuel, I have only filled up at Costco, so i recently put only 2 gallons of local 76 R95 and that has just lit up my check engine light, which gas do you recommend or there is more going on with my truck.

[@Myksgarage]

I've only put diesel #2 in mine

[@ronmac1832]

In older diesels, it seems to take forever for them to warm up and stop behaving so sluggishly. Is this an issue anymore?

I haven't had that issue

How do you like the Sierra vs the Yukon?

It's apples to oranges, but I love Sierra as a truck!

if your in canada don't let the def fluid get to low as it can freeze lol

Good tip!!

[@lucabolani946]

Italy, Europe in true..diesel means preserve some money and, use a moore efficent kind of Engine. Use appropriete Oil, and change It offten as required as the producer says. Use additive offttly tò keep kleen the fuel system. Warm up and cool down the Engine...2 minute After the driving..It preserve the turbo...and...use It for mittel/long distances...not fir turn arround 10 minuts arround the city.....

You can also get Kleen Def at Menards for less than $10 for a 2.5 gallon jug & it’s usually relatively fresh according to the date codes on the boxes

[@caseyrolfe72]

Walmart super tech for 8.88. Been great just if you get more than one keep it in the Air conditioning and check the manufacture date. Really important that you do that. DEF doesn't like warm or hot temps for self life
