Jonathan at bimmerdiffs has stated that redline "shockproof" fluid causes LSD failures. Not sure what fails but he has mentioned that in other threads.
I've mostly used Mobil 1 and amsoil both have held up well at ~20k mile oil change intervals. 75w-110 is what I've been using in the Ti with small case LSD. __________________ ~Dave~
