TBH, no clue. I'm not sure what the facination here on BITOG with the no-VII thing is but hey, whatever floats folks' boats...I've thought about trying it in my son's car. Seems like the high-quality VIIs in the Euro blends they make should work in any application where maintaining viscosity is critical. Basically my HPL Euro 5W40 has a higher HTHS than any of their no-VII line so take your pick...reducing visosity shearing (that is really low-to-no anyway with their oils) or have more HTHS which to me is more important. I'm not sure what HPL/Dave would actually recommend the no-VII for w/r to application vs. these Euro or Super car oils?
