Does anyone know the HTHS of these oils?

HTHS of 5w30 oils that interest me.
Valvoline Restore and Protect 3.24
Valvoline Extended Protection Full Synthetic 3.2
Valvoline Extended Protection High Mileage Full Synthetic 3.3
Quaker State Full Synthetic ?
Quaker State High Mileage Full Synthetic ?
Havoline Lifelong ?
Supertech High Mileage Full Synthetic ?

The Valvoline HTHS numbers above are copied from another member's earlier HTHS thread. He said he got the numbers from Valvoline tech supp. I assume they're correct?

Look at the grades and or the approvals and see the limits. If you think you can fine tune it within a grade and believe it makes a substantive difference then you’re a lot better than me.

All those are b/w 3.1 and 3.3 cP.
That's what I can say for sure.

Which one has the the best oil base? - probably Valvoline Restore and Protect.

If you’re looking for a hths > 3.5 then acea a3/b4 is where to look. Between most of these api/dexos oils you’re looking at, there’s likely not going to be much difference

I'm not looking for any specific HTHS. I'm very happy with 3.3. I'm happy with 3.2. I'm OK with 3.1. I'd probably be OK with 3. I don't have any flat tappet cams and my vehicles full op temp varies from 195-215F. Hottest day ever for one of my engines was 230F, but that's rare.

I asked about those oils HTHS because I'm curious how those oils compare to each other for HTHS.
