New bulletin/Campaign 6.2 L87

[tbarn]

New bulletin/Campaign for '21 -"24 Silverado, Sierra etc with 6.2 L87 engine. Has to do with engine sudden stop (blown). Very early. No parts available at this time. NOT ALL 6.2's are involved. Which ones is unknown. Dealers have a list of inventory to inspect and stop sale if inspection fails. No much of an inspection though. Check for P0016. If it is there then stop sale. If not then change oil and filter to 0-40, change oil fill cap to reflect new oil grade, send it. Again NO PARTS at this time.

Corvette/Camaro/Blackwing 6.2 LT1, LT2, LT4 and LT5 use it currently as of 2019.  Nothing new.  0w20 was/is in the pickups solely for fuel economy reasons.   

[newdude]

Two versions.  N252494000 and N252494001.  000 is the one for everyone who owns a 6.2, 001 is for dealer in stock inventory. 

 

Here is 001 so everyone has an idea of what is coming for 000.

Boy oh boy GM has blinked. Metallurgical issues exacerbated by fuel dilution will only be DELAYED using 0w-40R by Mobil.

Buy enough time until they can get enough engines for full replacement perhaps?  Because I think that's what they might be trying here.  They know they won't be able to meet demand for it so why not stratify it.

It will be interesting to see if they cover past warranty, knowing there was a defect, or is it covered forever if the specific parts fail past warranty?  

 

There is always a better oil option.    https://www.amsoil.com/p/amsoil-signature-series-0w-40-100-synthetic-motor-oil-azf/?zo=521390

Most likely. @Black02Silverado has run Amsoil 0w-20 in his 6.2 with do far no issues.

After one year of being in charge of manufacturing this leader is resigning. Related? Maybe.

It would have been cool to be a fly on the wall in all of his meetings and offices to hear what exactly is going on.

Hmm.  Not sure why that would be?

Glad you posted that 0000 was for all of us and 0001 was just for dealers. I tried to get answers from two dealerships today and they said they dont know what to tell me lol. They see the recall but say there is no remedy for it. I said It says at the bottom to inspect then change the oil. They stated again it says at the top no remedy so there is nothing they can do.

The defect is the 0W20 oil

Name it...the exact metallurgical ISSUE. Can't be done. Again, attempting to 'say a thing true'. . PROOF! and failing motors is proof only that they are failing. REASON...LOGIC....

 

Not the OEM's first rodeo on oil related failures. Anyone remember taking all the Phosphorus/sulphur out of flat tappet cammed motors just before roller cams became standard fair?  And the hideous number of lifter/lobe failures? NOT metallurgical. Motors are not moron proof.

I am due for an oil change, I wonder if I should just swap out the 0W20 I recently bought for the 0W40 and go on from there.
