I have a 2002 BMW 530i and have been using GC which I believe works very well in this engine. Since it appears GC is disappearing, I'm thinking about my other options such as BMW 5W-30, Mobil 0W-40, Synpower 5W-40. I don't really want to mail order motor oil. I'm also interested in considering PP 5W-30 European Ultra Formula. I haven't seen this in a few places, but have not been aggressive about looking either. I want to continue meeting the BMW LL-01 spec. Any thoughts about the PP Euro Ultra or my other options? Thanks.
