Boy, SRR's VOA doesn't look like any d1G2 oil I have seen so far...I think I saw an SN+ oil with Ca just under 2000ppm, but there was certainly no Na. Don't believe that was a d1G2 oil...
I'm certainly no oil formulator or tester, but I gotta think that there was a screwup and that d1G2 bottle got filled with older oil. I have been very tempted by that Ravenol DXG, but I've already been burned once trying to buy the d1G2 version (although that was fully rectified at only the cost of maybe half an hour of my time) and I think this thread puts a stake in the heart of that fascination.
