Got some Edge with SPT 5w40 for my VW on the BOGO sale at Advance and it is Green like Prestone? I know the GC 0w30 was Green for a while but I did not know that any of their other oils were Green at this point. It is SM rated if that makes any difference. Just wondering if any of the other Castrol products were still green since I have not heard anyone mention it for quite a while.
