That's not even remotely close to the same thing. AMSOIL and HPL don't recommend an oil with an HTHS below 3.5cP for approvals that require it. In fact, when David put together the 0W-20 for me using the A3/B4, 502 00, A40, 229.5 additive package, they EXPLICITLY note that the oil CANNOT be formally approved or recommended for any of those applications for that reason.
A3/B4 requires a minimum TBN of 10 and an SA between 1 and 1.6%:

But we've got Triax claiming their VX 5W-40 is both C3 and A3/B4:

While it's SA is 0.8% apparently, and TBN is 8.5:

It's also claiming LL-01, which is based on A3/B4, which means the same ACEA limits apply on SA and TBN.
These things are problematic. Hopefully they are inclined to revise their recommendations based on this thread, since they are obviously reading it, rather than get upset. This is constructive criticism.
I'll personally never use their products just due to their outrageous and outlandish marketing, but if they accurately represented the intended range of targets specified for the additive packages they use, I'd be less inclined to criticize whenever their products are brought up.
