I stopped in pep boys today. They had Castrol 0/30 on the shelf, on the bottle it says Made in Belgium, Castrol 0/40 in the 5qt jugs says made in Belgium. Castrol 0/40 in 1qt bottles says made in Germany. So is the Castrol 0/40 in 1qt bottles the new GC. I guess the only way to tell would be to do a VOA on all 3?
The 0/30 said a/3 a/4 API SL
