That is exactly what I wish for, then you can compare products. Still I would happily use any of the big names SynPower, M1, Edge, SOPUS (PP, SHU).
These new SynPowers all look good. They all carry good TBN (9.3), good zinc (830 ppm) and the same SA (0.97 %). In terms or Noack volatility the 5W20 ( 7.6 %) and 10W30 (8.0 %) are both fairly low. The 5W30 wins on specs being both Dexos1-Gen2 and Euro A5/B5, and it's Noack of 9.3% is still under 10% which would do me fine.
Thanks for posting.
