I've been to several Autozones in the last few days and all of them had GC. In fact, I havn't seen the US stuff in quite some time. I've also noticed that AZ now carries Castrol 5w-40. (Never saw it before at AZ) On the front of the bottle it said specially formulated for VW engines. I should have looked at the specs. It was $4.99 qt. I think it's only a matter of time before we start to see these higher end oils become mainstream here in the U.S. Good news is I think GC is here for good and Castrol is ONLY selling the German oil now.
