Unfortunately, I realized that the current supplied by Amazon canister no hologram on the label has. On the product photo, however, was clearly a hologram to see (top right on the front label). To make matters worse was at the point where the hologram should be even a sticker attached to the Obscure place! The hologram is attached by Opel / GM be able to identify more easily to counterfeit products. In my opinion, the guarantee of authenticity and thus the certification (oil quality) without the hologram is not given. I returned the item.
