Yes, it's the same stuff. The specs haven't changed.
Interesting the PDS says it's A3/B3, A3/B4 but it only has a HTHS of 2.9. A3/B4 requires HTHS 3.5+. Is the PDS wrong? If so, why is it so difficult for oil manufacturers to get this information right the first time?

Castrol reports the minimum HTHS for Xw-30 grade oil which happens to be 2.9. Of course in case of GC this is wrong since it also meets ACEA A3 which means it actually needs to have HTHS of at least 3.5 as you noted.

I'm scratching my head as well. Castrol is not the only company that sucks at it. Pennzoil comes to mind as well...
