Good Stuff yea or nea.... I'm currently running Gold GC in my wife's GTP and Green GC in my Formula. I didn't have anymore Gold GC,and I didn't want to get into my stash of Green GC. The closest Auto-Zone to me only had German Castrol with a lot number from this year. The last time I was in there sometime back they had plenty of Gold GC,but I was hunting for Green. I've been tickled to death with the Gold GC in my wife's GTP. Is this lot good as some of the older stuff? If not, I'm going back and trying another store further up or down the road.
