Haha there is definitely a lot of information in this thread!
Well I was reading a bit of bob the oil guy, I'm glad I asked this.
Thanks for all the info guys, and I hope others can read this to get info too!

There is more to be considered than just the GM recommendation though. Not all w30 oils will be the same, as there is a range of viscosity that can still be called a "30". I'm sure you personally are aware of this, but I'm just pointing it out to people reading this thread. UOAs seem to indicate that LS1s respond well to oils on the thicker side of a w30 or the thinner side of a w40. Speaking in terms of synthetics anyway.
But I do agree (and think this was the intended point of your message) that for those in doubt, or that don't care to do a lot of research and testing of their own, you're usually best off to stick with OEM grade recommendations.

OP, glad you started reading the bob is the oil guy information. I'm sure you are on the right track now.
