Hey I finally found GC in my neck of the woods. It's not in any Walmarts near me, but I found it at the Canadian tire store near my work. So it only comes in the 0w30 flavour. All the other Castrols in the same type of bottle are "Made in the US". But I also found a Castrol Syntec xxxxx ( I can't remember the rating or weight of it ) but it was a "Made in Belgium" What's that all about. And Yep, I bought one bottle just to see it for myself ( I'm at the first stage of an Auto-RX treatment so it'll be a while before I even think about synthetic oil ) But I had to see if it was green and find out how it smelled. I even got my wife to get a whiff of it, and she thought I was a freak. Anyways I'll bug you all much later if it's an oil for me.
