15W50 Mobil 1, every 3.5k, comes out looking like honey. :) Got to love a clean engine.

Take a look at Mobil 1's website, they list 5w-30 as working best at like -40 to 30 F in the E30's. Whereas the 15w-50 works at -5 up to around 90 I think.
It quieted down a bit too.
bmwguru suggested I run 15w-50, and I'll be stickin with it. ;)- Sean Hayes
