Based on this, it appears to be the same as the European Castrol Edge Professional A3 0w-40.

I really wish I could find a VOA for any of these, real curious what the add pack looks like.
The product that's identical to this in specs is Edge 0W-40 in Australia. However its TDS says it's closely related to SLX 0W-40 (229.5), but doesn't actually have the approval. Lower VI than M1 and also lower HTHS, 3.7cst. CCS is also slightly higher than M1 (5800 vs. 5700), so MRV might be too. The approval info from Castrol NA says it's got 229.5, which to believe..

Castrol's marketing department is appalling in every way. [censored] ads, documents, branding. Good enough reason to avoid their products.
That's a very old PDS. Back then there was Castrol Edge 0w40 A3/B4 and
Castrol Edge Sport 0w40 C3 (Ford 5.4L approved!)
Now we only have
Castrol Edge w/ti FST 0w40 which is A3
