And look at that C4 oil, low SAPS (< 0.5% SA), high HTHS (> 3.5 cP) and Noack volatility < 11%.
This is the lowest volatility of any ACEA sequence yet. It reminds me of a Porsche C30 or VW 504 / 507 OEM oil. They are usually built to a very high standard, and typically PAO based (the ones I have seen anyway).
