What vehicle requires that spec oil?
If I remember right, ACEA A3 requires a HTHS viscosity of at least 3.5cst, and I don't know that any 0w-20 will be able to do that.
0w-20s can make ACEA A5, which has a lower HTHS viscosity limit of at least 2.9cst

That’s not possible.

The closest you'd get would be a 0W-30.
Would you mind sharing the link you found? That's interesting.

Or just making an error in their claims.

I'll see if I can find it again. Should have bookmarked it ....

I'll try to find the site and we can all take a look. I'm not too knowledgeable about some of these things, so I could be wrong or misread what I saw (or thought I saw).
That oil does not exists. Maybe some dedicated racing oil that no public has access to has 0W20 grade with HTHS above 3.5.

Hey, it happens to all of us if that's the case. No worries.

Millers Oils NANODRIVE CFS 0w-20 NT+ Fully Synthetic is A3/B4
Millers Nanodrive CFS 0w20 NT is A3/B4
Nor a cheap oil bit not a dedicated race oil and its available to buy over the counter. Though likely simpler to buy online from OpieOils
How is this not dedicated race oil when everything they say is aimed at race engines:
NANODRIVE CFS 0w20 NT+ Engine Oil - 5 Litres
A fully synthetic Triple Ester NANODRIVE Technology low friction formulation suitable for modern competition engines where maximum power release and ultra low friction are required. Part of the Competition Fully Synthetic NT+ range of engine oils and incorporates Millers Oils second generation...
Considering that’s not an SAE grade designation then you can call it anything you want.
Millers is not an A3/b4 oil...
The viscosity figures posted in the data sheet suggests it's likely not even an A5/B5 when it comes to HTHS

Anybody willing to calculate the 150C kinematic viscosity abd transform to dynamic to see the maximum possible HTHS? With the kinematic viscosity already below 3.5 cSt it can't be A3/B4

I assume you have never heard of Millers Oils?
Who cares about SAE, this is the European and Import Section.
And the OP asked about a 0w20 A3/B4, which this is.

It isn't.
