I know of a place that sells Castrol RS, but that's only in the 10W-60 formula for the M cars and that thick viscosity will screw up the VANOS unit on my Bimmer. Plus it's not gonna start this winter.

Honestly I don't know about you guys, but the places where I can get good synthetic oil are limited in my area. It's the dealer, the indy shop (which also sells the BMW oil or the Castrol RS), the Advance Auto Parts shop, or Pep Boys. I know Autozone carries the Castrol 0W-30 (whether that's US or Euro-spec I dunno), but I'm not driving deep into DC and getting lost just trying to find a store.
