RB, I didn't do a Blackstone on the last change [lots of miles in only 90 days .... sheesh .....], but will on the T6 [included the liqui moly 300mg additive, too] in this change and track both (1) oil consumption and (2) compare the Blackstone on the T6 to Mobil1 0w40 Euro. Not a perfectly scientific test/comparison, but should be interesting. I'll do the DISA rebuild next service, and hopefully find what appears to be an intermittent recurring vacuum link in the secondary air pump hoses [svc engine light keeps recurring, reset with my Peake tool] while in there. Squid, I'm interested in your impressions of that OBD software; I'm still using my circa-2000 Peake tool.
