We also get Shell HX8 5W30, it's a Group III synthetic, often at a good price. But I've never used it.

I suspected the Noack is just over 10% which is why it's MB 229.3 rather than 229.5
I usually pay a bit more and buy the pure-plus GTL Shell Helix Ultra 5W40 or the MB 229.5 rated Castrol Edge 5W30 A3/B4 which carriers more ZDDP than the HX8 (SL Edge Vs SN HX8).
Or I pay a bit less and get the Castrol Magnatec 5W30 (SN & A3/B4) also a Group III synthetic.
