I’d sick with Mobil, factory fill on some of the best cars like AMGs and GT-Rs for a reason, or royal purple.
Look for a proper group 4 synthetic, easiest way to tell what’s real and what is a gr3 ‘synthetic fortified’ is by looking at the pour point in the oil spec. Aim for -45 to -50°.
I use Delvac1 ESP in the XU6 based on advice I was given by an oil tech.
