The quart of Castrol Edge 0W-20 tested was purchased online from Advance Auto Parts. VOA is by Dyson Analysis. It appears to be primarily Group III oil, but the surprise is the titanium additive instead of something conventional like ZDDP.
I searched BITOG for references to oils containing titanium. About a dozen threads on ConocoPhillips use of "liquid titanium" (mostly in Kendall GT-1) from additive supplier Afton Chemical. Is Castrol using the same source? I don't know. The story was broken by Tom NJ on Nov 18, 2008:
