IMO, HTHS should be listed on the bottle instead of a viscosity range. Even between oils with the same numbers on the bottle (eg. 0W-30), you can have different film strength and oil pressure.
0W-30 isn't saying much, but a 0W-30 with a low HTHS like Mobil1 (HTHS 3.0) compared to a Euro 0W-30 like Euro Castrol 0W-30 with an HTHS of at least 3.5 will have the Castrol behaving more like a 40 grade.
