Visiting Castrol Germany's website this AM, I no longer see the 0-30 SLX. The only available 0-30's are TOPUP's and they do not carry the BMW-01 certification. Can someone else confirm this?
The one's we know are still there...the RS 0-40 (may be the BMW 0W-40), RS 10-60 (BMW/Castrol TWS oil) and the Group III HC (Dynatec) 5-40 (Belgium).
