Stopped by a couple AutoZones tonight looking for some GC. I found a couple quarts of Castrol Syntec 0W-30. The bottle does not say "Made in Germany" though...it says something like Made in USA from domestic and international stock...not to be sold outside of the US. The batch number was M013116855A1 1631. Is this the right stuff? I didn't buy any just in case. Have pics if anyone is interested. Thanks in advance!
