Castrol is a marketing gimmick. They paid tons of royalty fees just to get there logo on our E9X oil caps. Also, never use 0W...it must be 5w/30 or 5w/40. Personally I go for 5w/40 for turbo charged cars, but the brand is very important!
I've tried many n have settled for Motul. Check out there site n see the RnD they have put in all there lubricants. Even there coolant is great but I usually stick to the BMW pre mixed coolant, if not available I only use Motul.
Last piece of info, the more mileage you have, the more viscosity is needed. Please check out this great site- bobistheoilguy.com
