GM now saying to use 0w40 in 21-24 6.2L
- Thread starter That John dude
- Start date
It said the bearing caps are cast nodular iron, not the rods themselves.
Good to hear man. Do it and never look back. I honestly dont know why anyone with the Gen V didn't stick with 5W30. I know all of mine and everyone who would listen to me has never ran 0 20.
Was GM certified for years. I'll tell anyone. Do not run 20 in anything GM. Goes for the V6s and turbo 4s too.
Interesting the recall is for '21 & up as the L87 has been in production since '19 in pick-ups, 2021 was the first year it was available in SUV's.
Whatever happened between the production of the LT1/L86 and the production of the L87 needs to be investigated by GM Powertrain.

Alot of the times they honestly dont know exactly what is causing it, so they try different methods with very few R&D hoping it is resolved (but it isnt) and quality isnt like it was in the 70s where they would shut the whole line down until its resolved...heck no. That costs them and their suppliers (that they have committed buying so many dollars worth) too much....so before you know it they have millions of defective parts and would rather hope warranty runs out before it fails OR they get lucky and fix it by accident. New tooling costs thousands if not millions in some instances. It's all about the $$$
Sad reality.

They're cracked cap....meaning the rod is formed/forged as one piece.
While not perfect, I see quite a few of these engines, and for the most part they seem to do okay. Even my GF’s work Colorado (which gets beat on) seems to hold up pretty well. I’ve seen a few failures, with one being put on the 10k oil change diet.
I look at this engine like I do the 1.5 and 1.4 turbo engines in my GM products- frequent oil changes are a must.
I’ve had no issues with the two turbos I have now, even though I’m told by “others” how bad these engines are.
Perhaps a oversight on the authors part, appears the main caps are cast nodular iron and he assumed both were... /shrug

Can you provide a link where you found this recall? I’m not finding it online.
My boss has a truck with this engine, seems to be burning some oil.

Only one. Mobil 1Supercar
I work for a GM dealer, and was browsing a GM tech page on fb after work hours. That’s how I found it.
That’s what we stock for the “new” Escalade V’s
Do you know failure mode? Catastrophic, oil burn, or??
