I praised it bcs. what was inside. Originally, until 2012 or something like that Edge 0W30 was made in Germany, not Belgium. 0W40 was made in Belgium. Then they switched, 0W40 production moved to Germany, and 0W30 to Belgium.
5W40 is not equivalent as it is Group III product.
Until 5-6 years ago, it did not even have MB229.5 approval. It was always lower-tier product in Castrol's lineup. Country of origin is irrelevant.
