Ok I'm still unable to locate german castrol anywhere. I've been to three autozones and they still have the old stuff since 0w30 sells so poorly. Even the stockrooms have the old castrol. Where else can you get it?
Will an autozone manager order it for you? Are there any new autozones around? The newer stores don't have the old stock. Can you have a BITOG member send it to you?
It does not have an API starburst on the front. It has red, not yellow on the black bottle. Most importantly, it says made in Germany on the back of the bottle.
