Main Bearing Failure with 6.2L at 3,200 miles

[Srittle001]

You managed to get 47K miles on the engine before it spun a bearing. Care to share what oil weight/ brand and what oil change interval you were using before the old engine went south?
...

Was changing oil every 5-5.5k miles at the dealer and not sure exactly what they were using.

What's crazy about this is, while the vast majority don't/won't/haven't had a problem yet, there is enough failures floating around to make you stop and think every day.... Am I driving one of these ticking bombs or not? And most people's outcomes won't be a 5-10 day fix.....

So same issue on my 2022 Yukon Denali 26000 miles, I thought I was good until heard the noise and lost power , coasted to the side and had it towed to dealer

The dealer would use the recommended 0w20 oil, which may be a contributing factor to the failures these engines are seeing.

I don't like the idea of 0w20 oil either (slippery water) but with all the oil dependent tech in these motors what else can be used? But I suspect the failures on this series of motors is more due to block shift and casting materials.

10w30
5w30
0w30
0w20

logic dictates that future recommended oil will be

-5w20
-10w20
-10w10

Slippery water indeed!
