I just wanted to let you GC lovers know that I finally found some at an autozone near me that I had overlooked, I asked the counter guy if they had any and he said no but I went and looked on the shelf 10 or 15 quarts of Made in Germany Castrol Syntec 0W-30! I'm going to go back today or tommorow and take all the have. Still have one question though where is the number on the bottle that tells what batch it is?
