Too bad they fail to mention that it is recommended for Z3M/Z4M's (however they get every other S54 application).
Maybe Redline is worth trying out.

From a cold climate perspective (something I have to be very careful of), the dynamic viscocity of Redline 10w60 is much higher at -25°C than TWS Motorsport (6500mPa.s vs 4800mPa.s).
