Whoop! I visited 2 different Auto-Zones today and scored ten quarts of Green GC!! There was some of the ancient Ow30 in front of the good stuff in both places, so I almost didn't bother to look. Both places also had bottles of 0w30 with no lot numbers on the bottom. The bottle had the 0w30 with the red background, but I belive it said "Made in the USA with imported components." All in all, I'd say it was a very fruitful trip! I'm now up to 21 quarts of green GC! I know that's meager by some standards, but I just got started and the green is getting harder to find! I've missed out on trips to 3 other Auto-Zones in the last couple of weeks though!
