New guy here...   Hoping to give my .02 in case someone is considering the 3.0. And it’s also for the guy who is believing all the negative BS reviews like I almost did.    Long post, so

When I was shopping in November, I had salesman tell me: -1500 diesel didn’t exist -it’s a duramax/Allison so it will last forever -It’s a 1500 but can pull like a 2500 with the diesel

Just checked with gm chat and my  LT with the 3.0 is sitting on a rail car 300 miles from dealer. Looks like I should be in possession of it sometime next week. Ordered this on 11/13, was built on 12/17 arrived in Fairfax, KS on 12/28. Fastest new vehicle order ever for me.

Congrats !!!

 

My 3.0 RST Loaded with goodies was built on 12/20 and should be in about 3 days after yours.  It has been a great experience thus far for me too.    Central Arkansas area.

I have some to the conclusion #1 diesel drops mileage 3-4 compared to #2 and larger more aggressive tires takes about the same off. Trying to run a 50/50 blend now and that seems to be a bit better so far.

Last weekend driving for Christmas went a little over 300 miles round trip. Was running straight #1 with a speed of 70-80 and probably around 40 total minutes just idling letting the truck warm up before I load my daughter (3 separate times). On the tank still averaged 20 mpg. Switch that to #2 diesel and I see that going to 23-24 pretty easy

We just picked up our 2020 Sierra 1500 Denali diesel today. For the 70 miles we've driven it, we are happy with the purchase.  I really wanted the SLT with X31, but when we drove it and then the Denali with Ultimate (both diesels) my wife really liked the ride on the Denali better.  Since she will drive it more than myself, I felt that was the way to go.  This will be our 3 diesel in the family with the other 2 being Audi's. For some reason, I really like them (along with the vastly superior fuel economy).

Happy wife, happy life.  Congrats on the new truck!  The TDis are great engines, despite the recent issues with misrepresenting the emissions from VW.

Couldnt agree more. We never had any issues with our TDI's and even after the "fixes" they are pretty much as they were before.  So all good. .

Where are you getting #2 diesel? If your in ND your definitely getting winter blend. Cetane is too low. Check out Optilube, kick your lubricity up and you cetane and you'll get better MPGs. #2 is going to plug your DPF DON'T run #2, these engines are ULSF ONLY! Dealer will void your warranty.

#2 is also ULSD. Up here there are a few different kinds of diesel available, all safe for use. #1, #2, blended, and Cenex up here also has a few special blends of their own. Difference between them are gelling points, cetane ratings, additives, and if course cost

It is illegal to manufacture or sell in the us or canada any diesel that is not ULSD.

(there was a time during the conversion of the fuel supply when both LSD and ULSD were available; road fuels were changed first)

 

Even coloured 'off road fuel' is ULSD.  Dye is just (now) used to indicate whether the road tax was paid. 

 

Yes, there is diesel that is not ULSD available in parts of Mexico.

      Another 6.2L engine failure!

      By MASONV88888888 · Posted

      My 2025 Silverado 1500 had to receive a brand-new engine (long block) under warranty last month at only around 16,500 miles. Before the replacement, the truck repeatedly displayed "Engine Oil Level Low" warnings, even though the Oil Life Monitor still showed around 50% remaining after about 6,000 miles since my last oil change. After seeing the warning several times, I checked the dipstick with the engine cold, and the oil level was completely normal. The next day, the message escalated to "Add Engine Oil." At first, I assumed it was just a faulty oil level sensor, so I brought the truck to the dealership. After inspecting the engine, they found internal cylinder wall scoring and ultimately replaced the entire long block under warranty. Before this happened, I was planning to install a 4-inch lift and suspension upgrade on my truck. After needing a new engine at just 16,500 miles, I honestly don't see the point anymore. I also contacted GM to ask whether my vehicle qualified for a buyback, but I was informed that it does not at this time. Anyway, this experience has left me with serious concerns about the long-term reliability of this engine. I sincerely hope NHTSA expands the current investigation or recall to include 2025 model and performs a thorough inspection of affected vehicles. My biggest concern is that these engines may fail shortly after the powertrain warranty expires. If GM truly stands behind this engine, then at the very least, please consider extending the powertrain warranty to 10 years for affected owners. That would go a long way toward restoring customer confidence.

      OCI, not when but why?

      By Grumpy Bear · Posted

      Without exception but then I'm the odd duck, right? I know what goes into that test, how it is calculated and thus how to beat it. But EPA values are often not beaten by the general public and the government has in past years adjusted the means and methods to come to those values to more closely approximate "Joe Average".    The only real trick to beating that EPA average is don't drive like "Joe Average".    It's the same method you used to profit from "Economic Migration" and in doing so beat the 'stats'. But you, like me, are not "Joe Average".     The thing you don't seem to grasp is this "Purchasing Power Index" isn't forward looking. It doesn't predict what it going to be but looks backward and states what it was. They are not telling us what the THINK, they are telling us what they MEASURED. Example:    Wife says "I'm going to lose 40 pounds by Christmas". May she does, maybe she doesn't but the doctors office who weighed her when she made that statement and again at Christmas only REPORTS what the RESULT was. You and I can banter about what was possible and what aunt Tilly did till the cows come home but the result is the result. Arguing otherwise is.....irrational. That's all I'm saying. This isn't about:      What you are calling a 'Statistic' is a RESULT not a CALCUATION and as a result the RULE. Like gravity as a rule, it can not be broken.

      Rattle in the rear!

      By MASONV88888888 · Posted

      Just wanted to say thank you for posting this. Years later, your thread is still helping Silverado owners.   I bought my 2025 Silverado 1500 in January 2025, and I've had what feels like the exact same rattle since day one. After reading your findings, I believe my truck has the same issue with the cable carrier contacting the rear sliding window. To be honest, I had pretty much given up on pursuing the issue. It wasn't until I recently drove another brand's pickup that I realized just how quiet their cabin was—and how noisy mine has been all along. On my truck, the rattle happens on almost any paved road, gets even worse on rougher pavement, and I can even hear it during braking and acceleration.   I actually referenced your thread when submitting my case to GM, hoping they'll recognize this as a recurring issue instead of treating it as an isolated incident. The reason I reached out to GM first is because my dealership told me they would need to keep the truck for at least two days just to diagnose the problem. I was concerned that even after two days, they still might not be able to identify the source of the rattle before giving the truck back to me. I had also asked a few dealerships about this issue during previous service visits, but none of them seemed to know what was causing it or had a solution. That's why I decided to contact GM directly first, hoping they might already have an official repair procedure or guidance for this issue.   I also hope GM eventually comes up with an official fix for this problem. I have a feeling there are many Silverado owners experiencing the same rattle, but most either choose to live with it or simply don't know what the cause is.   Really appreciate you taking the time to document your diagnosis. Your post is still making a difference years later.

      Do you have access to BP fuels? Some stations have Silver 91 E-0 priced the same as their 93 E-10.  There is a local Marathon with 90 alky free for $6 a gallon but I go down the road to BP for $5-ish. They also have a 100 E-0 but that stuff is $10 a pop.
