FYI

HKS recommends a 40 weight engine oil:

https://www.hks-power.co.jp/en/produ...arger/db/20246 (under installation notice)

Here, in Europe, specifically in Germany, most HKS GT SC users use 5W_40 or 5W_50 from Motul or Ravenol (excellent engine oil, group IV/V + Tungsten/Molybdenum additive, also used by Gazoo racing).

I use 5W_40 (Ravenol RCS) with my HKS GT2 SC (including HKS oil cooler) / built engine combo.

Cheers
