Hi, I went out today and actually actively looked for gc green. I was lucky and found a good batch at my second autozone. I bought 7 quarts of it. I made sure to look at the batch numbers on the bottom and found 6 M04xxxxx, 1 M03xxxxx, and 3 or so M02xxxxx. The 3 quarts of M02xxxxx didn't say "made in Germany", but instead "made in USA". I thought the batch number M02xxxx meant that it is gc green? I didn't buy those bottles because I wasn't sure if the formulation is the same as the German made stuff.
