So, I just changed the oil in my 2004 Audi S4 with this Leichtlauf High Tech 5W-40. It's a Group III synthetic.
The PDS from the Liqui Moly site was pretty informative:
Viscosity class : 5W-40
Density at 15 °C : 0.855 g/cm³
Viscosity at 40 °C : 90.0 mm²/s
Viscosity at 100 °C : 14.7 mm²/s
Viscosity index : 171
Flash point : 236 °C
Pour point : -33 °C
ASTM colour : L4.0
Ash, sulphate : 1.2 g/100 g
Lacking a few specs, so I emailed the company and received this additional info:
Dear Mr. X,
our product has following data :
TBN = 11,3
NOACK = 9,6
HTHS = >3,5
Mit freundlichen Grüßen / Best regards

Will do a UOA next year.
