Great read on proper oil selection for turbochargers..

Yes, Advance Auto (and most other popular parts stores) have VR1 on the shelf. Like TDI said, thrust bearing failure due to low anti-wear additives is not a global concern with turbochargers, but there is no reason not to run the better stuff (esp given the fact that VR1 is 4.50 a quart). None of the Rotellas are ILSAC GF-4 approved, so they should have the higher levels of ZDDP etc. However, I have not seen a VOA (Virgin Oil Analysis) on Rotella in awhile, so I cannot verify this.
