I contacted Castrol USA and asked them about the stuff they make for BMW. All they could say was that it was made by their European factory and they had no way of contacting them to help me find out the specs on it.
One interesting thing is the specification differences between Castrol Syntec 5W-30 and BMW High Performance 5W-30. Castrol's Syntec only meets the European ACEA A1 specification whereas BMW's HP meets the much tougher ACEA A3 specs. ACEA specs (when met) are on the back of the oil bottle.
Seeings how BMW Car Club members typically get a 20% discount on oil and filters from dealers, paying about $2.90 a quart for BMW oil sure beats paying over $4.00 a quart for Castrol. Besides, no other oil costing less than $3 a quart meets the stringent ACEA A3 standard BMW wants in their engines. BMW used to use Valvoline 5W-40 synthetic selling to BMWCCA members at about $7.00 a quart. This new stuff is much better.
I've switched to BMW HP 5W-30 Synthetic oil in both the Z3 and our '00 Volvo S80 sedan - what a deal!!!
