Not to derail this thread. But I highly doubt it.
+1 As it is nearly fact anyways. Keep in mind because of GM's screw up with the OLMs and having to replace engines (only of the DI/turbo'd ones), they are not going to deny you a new engine as long as you prove fresh oil is going in, DI or not. I've seen this happen to a few Traverses already...granted, these engines will still go a while even abused.
Though in the best INTEREST of these engines running dexos (or better yet synthetics) to help offer extra protection....
My Neighbor at the end of the block runs PYB in his 12' Nox, but he changes it at 3k on the DOT.....and it's running just fine....
