I just wanted to let you all know that green still does exist. I bought 5 quarts, that was all i needed for my next oil change 2 of M02 and 3 of M04. When I went to exchange my gold gc for the green the AZ guy looked at me funny and said You do know these are the exact same oil right? I said no and tried to explain to him the difference of the green and gold, but it was lost on the poor AZ guy. They really need to have some kind of education course.
