Can anyone tell me what synthetic is “thickest”? I.E. highest range on the 30 side?

Generally 30w oils which are ACEA A3/B4 or C3 are on the heavy side. These are your Euro spec oils (BMW LL01/LL04, Benz 229.50/51, Porsche C30, etc)

Redline maybe Amsoil has some oils on the thicker side for their weights.

I think there is a way to sort oils on pqia site by their viscosity, hang tight...

Maybe not. PQIA site has changed so much, I think that feature went away.

Judging by your Korean models in your Signature and probably needing SN Plus ....
Quaker State Ultimate
Rotella Gas & Truck
Google both for data sheets.

However, Thickest is not Bestest. If it were, both of my Korean vehicles would be using ^^those-2^^

In mid-priced ($23-$35) 5w30s I like - in no particular order....
Pennzoil Ultra Platinum
Pennzoil Platinum
Mobil-1 AP
Mobil-1 EP
Valvoline Modern Engine
Valvoline Advanced
Kendall GT-1
Castrol Edge EP
Mag-1 Synthetic (I found at NAPA)

It's my Fine-As-Wine 9...... without the need to take a loan-out, for five quarts of TGDI / GDI oil.

Redline has crazy HTHS, their 5w30 is heavier than most people’s 40 (3.7 advertised vs. <3.5 ACEA spec)

Mobil1 High Mileage, they're not 5w30, but the Euro spec'd 0w30 oils tend to run on the thick side closer to a 40.

These results are from 2013. Don't know if you can assume similar performance today.
