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.

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.

around 11CSt, more Middle of the road, unless you're talking about the A3/B4 or C3 EDGE those are closer to 12.

Pennzoil Euro L is suppose to be a thicker 30wt. Running it in my STI for that reason while in warranty. Still need a UOA on it since switching.

Pennzoil Platinum Euro's are thick, the 5W-30 is around 13.2Cst. 0W-30 is also thick. Shella RGT 5W-30 is 11.7cst as is Mobil 1 HM...

That's funny... I'd also add Delo XSP 5w30, it's about as thick as you can get without being technically being a sae40.. it's a 100c 12.1cSt, 3.5hths with a tbn of 10. And dual rated...
