The Castrol Syntec that the dealerships use is a group IV synthetic while the vast majority of stuff on North American retail shelves are group III synthetics. Group IIIs cannot be branded as synthetic in Europe.

If you look at 0W-30 Castrol Syntec at Canadian Tire, you'll notice that it says it meets BMW's LL-01 standard and you will see on the label that is says made in Germany. All other Castrol on the shelf does not mention LL-01 and they are all manufactured in the USA.
