That looks like real Castrol to me. The "high" numbers are barely over the universal averages as well, nothing to get concerned about here IMO. I like Blackstone but seriously, flagging something because it's 4 ppm over the universal average? Stuff like that is more about selling you additional UOA's than anything else.
