That is correct. A5 requires an HT/HS viscosity of >= 2.9 and over-the-counter 0W-20 that is that heavy.
A1/B1 has the same HT/HS viscosity requirement, except that it allows >= 2.6 for an xW-20. Sulfated ash must be B1? It seems like it would meet A1/B1 on other metrics (its HT/HS viscosity is 2.7 cP according to XOM).
It is curious that XOM would publish that its 0W-20 AFE meets A1/B1 but not its 0W-20 EP.
