BREAKING: GM is officially recalling the L87

[GMCChevy]

I don't have a dog in this fight but I do have a question for the guys who do. Are you feeling lucky?

A thicker oil although it should protect better will NOT fix a manufacturing (part) defect. So my opinion is switching to 0w40 just prolongs it until the catastrophe happens. Whether that's an extra 5 miles or 50k.

I wish you all with 6.2s the best of luck! I know I'd be pissed with an expensive paperweight with low miles on it.

Like I said in an earlier post it seems like the different oil is a band aid solution to get them past warranty. It's the same trick that's been used forever running thicker oil in older worn out engines to try to keep them going longer only in this case they aren't old.
