Castrol revised the black bottle formula with liquid titanium now. PQIA's Castrol Edge black bottle test was dated in 1/25/2014 and the PDS dated 11/01/2013 with no titanium so the PQIA test was the previous formula. The new formulation PDS was released in Jun 20, 2014 showing that it's now engineered with liquid titanium. This oil is relatively new and haven't seen UOAs or VOA's yet on the amount of titanium it has. I've never see an oil that went though many formula changes. Was looking around at walmart when the black bottle is finally dexos1 certified with liquid titanium. They are different weights but the newer bottles show dexos1 certs / old bottle/forumlation Castrol Edge with Syntec : Castrol Edge formerly Syntec : Castrol Edge Fluid Titianum Technology. I guess were into version 3 now. Might do a UOA on my 02 Chevy 5.3L.
