I have an E30 LSD and when I run straight 75w-90 Mobil 1 I don't get any chatter. I briefly switched to 75w-110 Amsoil last fall and had a great deal of parking lot speed/tight turn chatter. I went back to fresh mobil and all the noise went away. __________________ ~Dave~ 98 328ti Morea Grun slicktop 11 128i space gray slicktop 13 JGC WK2 Deep Cherry Search | RealOEM |
