GM-kNOWLEDGE IS KEY

I am not an expert. The following U Tube, The Motor Oil Geek is a great knowledge base. This video helps explain the issue with GM V8's.

I'm confused by this video. Lake claims following the OEM's oil change intervals caused the problems and has a full layout in the video description on how you should your change your oil. Then, he does this video that reinforces what GM actually said was the problem - out of spec supplier-provided parts.

So, which is it? Is it the out-of-the spec parts or the oil change intervals? My money is on the parts. No matter how often you change your oil, you can't fix an out-of-spec part. And the number of engines affected actually is 17k. That's 3% of 900k.

Huh, did he ever say they listed a bad OIC? I thought he backed them up that the higher viscosity would help with the out-of-spec parts from the beginning.
