Group V does not necessarly mean better. Redline tends to run heavy for its grade so 5w-30 is a fine grade. Note that Redline is NOT API rated so potentially if you have an oil related failure BMW could deny your warrantee. Personally, I think that Redline is a great oil and if you like it would stick with it. I continue to use the Mobil 1 because 1) it is more widely available, and 2) it is cheaper at $4.75 quart v. Redline at $6.25 quart locally.
