So I'll start this off.

why did you get your truck with a diesel in it?

What do you plan to use it for?

Post a pic if you have one and fill us in on your options.

Was having problems with my 19 TB, originally wanted the 3.0 when I bought the TB but wasn't available in 19 and still isn't in the TB. Got tired of all the problems with the TB so decided it was a good time to try the 3.0 and the 10 speed. Ordered a LT with convenience package ll, Z71, bed protection package, all star package, advanced trailering package, safety package, side steps. No fog lights available from factory on the LT so I had to add them. Put on some dura traks which cost me 3-4 mpg. So far very happy with my purchase.IMG_0566.jpg.2f1a76ada00972116b5ffb72d4e13da2.jpg

I originally had a 2009 2500 6.6 Duramax and liked the power of the diesel drove it for 80,000 miles, but wasn't towing much traded it on a 2014 GMC SLT 1500 then on a 2016 Silverado LTZ 1500. When GM started talking about a six cylinder diesel I thought that would be right up my alley good fuel mileage and the power I was missing with the 5.3L. Picked up a 2020 Silverado 4x4 LT 3.0L with just some basic options end of January. The sticker was $52800 and I paid $41300 before tax and license, couldn't pass on the price. I also did the fog lights going in on Thursday to have them programed.

I have been wanting a diesel for years.  Since I only occasionally tow a motorcycle trailer with 2 Harley's it was a hard to justify a 2500.  When the 3.0 finally came out in the 1500's I went and test drove one and really liked it.  More power than my previous 5.3's and better MPG's.  I went truck hunting and had found a Chevy RST with a 3.0.  Before I pulled the trigger, I went to a couple of other dealerships to see what I could get.  I settled on a GMC SLT with the premium 2 package.  It had everything that I wanted.  3.0, 4wd, heated/cooled seats, nav, and front and rear parking sensors and factory running boards.  I have put about 1600 miles on the truck so far and like the truck better each day.  Back and forth to work I average about 21 MPG, on the highway is a little over 30.  I know it won't last but in my area, diesel is .30 to .40 cents cheaper than regular gas.

Any issues with the truck so far?  Are you satisfied with the power?

I own a 7000lb RV and tow 2-4 snowmobiles all winter long (3000lbs max).  Ive owned LLY, 2 LBZ, and multiple Ram Hemis.  My commuter car for years was a jetta TDI with a chip.  Loved that car.
Ive wanted a 1/2 ton diesel for as long as I can remember.  The 2500 were overkill for my needs and never got good mileage.  They rode rough and never fit anywhere easily.

So I wanted a hybrid of a 3/4 ton truck and my jetta TDI forever.  The ecodiesel came out and was a great first step.  GM had the small diesel in the colorado, but couple of my friends got it and had all sorts of issues with it, they traded in for the V6 gas version.  

Enter the 3.0.  Inline 6. And everything else I wanted forever.  I jumped on it for 2020 after waiting 1/2 year to see of anything really bad came up.  So far its filling that dream ive had forever.

I went from 2018 6.2 L to the "Baby Duramax" and I'm impressed at the power the 3.0 will dish out when asked. Not to mention the mpg.

Wind is an issue though. Heading into it, mpg drops to around 22 at 70 mph. With a tail wind, I get close to 30.

Still, not bad for a truck.

Not missing the 6.2 at all. (Except, the sound. I just loved that sound with a Borla Sport exhaust swap.)

I've wanted a truck for past six years.   Still own my 09 Yukon Denali 180k miles and still going strong.  But the interior is wearing badly so had been looking at 2500s but really didn't need to tow at the moment so dove in to 1500.  Loved the TB but really wanted a diesel because the 6.2L on my Yukon can't do better than 14 mpg.    So during covid I was having a hard time looking for an AT4 and after watching lots of YouTube I realized that Silverado RST was for me.    I'm afraid of all the bugs I might run into since this is a Gen1 engine but love the torque and off-the-line launch.    Just ordered the GM 2" "trail boss" lift and going to get that installed so essentially I get a TB w Diesel!   Will post before/after.....

I have not had the opportunity to tow with it yet but so far yes.  I have owned several 5.3's and have driven a 6.6 Duramax for work.  The 5.3's are great engines but even the latest generation feels a little sluggish pulling off the line unless you really mash on the gas.  The 3.0 you can really tell the difference.  I thought there might be some issues when passing but have been well pleased.

Just joined , hoping to join you with a 3.0 in next 90 days or so.  Im thinking RST trim.  Is the Z71 package include lift or is that all the Z71 is?  Hope to join soon,looking to see if some better deals upcoming this fall.

Hey all! 2020 LTZ Crew Cab Standard bed. Ordered in April, just got her two weeks ago, July 24th. I love this truck! 

I ordered pretty much every option available for the LTZ and opted for the 3.0L for several reasons;

- durability: diesel engines by design are known for the simplicity and longevity of the engine

- range: I make alot of trips from coastal Virginia to the mountains of West Virginia and up to New England, can't beat the mpg and range of the 3.0L with the 10 spd. 

- economy: Diesel is currently $2.05 while premium 93 that the high performance turbo gas engines need for top performance is $2.25 by me, and even then I'm still getting better mileage

- I'm a professional mariner and licensed to operate and repair massive diesel engines, with pistons and cylinders literally as big as the truck is long, might as well have one in my daily driver

- I will occasionally use it to pull a boat, Jeep, or horse trailer, but probably tow less than once a month. My towing will be all long haul highway towing.

I knew I wanted a diesel for my next engine, when Ram came out with their eco-diesel I was underwhelmed during several different test drives. Ford delayed releasing theirs, so I traded in my 2010 F150 for my LTZ.

Picked this up end of May, have 3,400 miles on it now. Had check engine light come on around 800 miles and it was for the DEF issue and had recall done around 2,700 miles for the update. Upper 20's for mpg. Towes great.

sorry to say I'm not a 3.0 anymore,  I went to 6.6. My 3.0 was not liking my camper and I went with the safe towing option.

    • Correct.  2019-2021 model years are serviced by a different p/n.  19420611.  Recall 2021s use 19420611.   The recall engines 2022-2024 model years are serviced with 12740076.     The difference between 19420611 and 12740076 is GM changed injector size for 2022.  The injectors are smaller on 12740076 with smaller injector bores in the cylinder heads to match the smaller injectors.  So you can't install a 19420611 in a 2022-2024, and you can't install a 12740076 in a 2019-2021.     Both engines are the replacement engine p/ns that are in the L87 recall.  So both of these are the updated engines.      
    • Looking for advice from this group. Took my flawless 2020 6.2 TB to an unnamed shop for routine rear brakes and oil change. Tech forgot to put oil back in after the full service and needles to say, destroyed my engine.  It’s all on their shop video so they are responsible.   I had my Chevy dealer do the analysis and they confirmed its compromised and said engine replacement. The manager said they only get GM reman engines from GM with full 3 yr warranty and the one they would put in is not same as what’s they are swapping out on 21-25 for recall.    I am looking for advice why that would be a different engine because obviously I had the good 6.2 year and replacing it has my concerns with that recall for 21-15   Also what’s the pros and cons of accepting the engine swap vs telling the shop that bricked the truck to pay up so I buy a new truck. I’m concerned about stigma resale eventually if I just decide to get rid of it after the swap or other issues showing up after the swap out.  
    • Just looked up my records.  I've never gone over 5000 miles between oil changes.  At 46K miles, I have 10 oil changes.  I hope that will help.  I also installed the disabler last year.  I've still had a few times when it didn't seem to engage (which I can tell because the start stop feature kicks in), but for the most part, I think it's working.  For some reason, GM did not include the number of cylinders running in the information screen like I had on other models.  In my Cadillac, it shows me when it's running on 4 cylinders on the fuel milage screen.  I can't find that on my '21 Denali.
    • you might read through the info on gmupfitter.com for your truck, to find a good power source.
    • Melling I believe is/was the OEM on the lifters who explored this problem some years ago. The white paper they generated on the topic indicated two items of note when I read it. 1.) They only fail on the switch. Prevent the switch, prevent the failure. 2.) The majority fail due to deposits messing up the timing of that switch. Anyway that's what I got from it.    Mine have always been active, 195K+ now, and my oil maintenance is surgically clean.    Of course this assumes good parts. That is no heat treat issue or machining flaws. I get comfortable that these issues are in the rearview mirror by about 30K. IMHO naturally.
