Review on Synthetic engine oil MOBIL 1 FS X1 5W-50, 4 l, 4 kg, 1 piece by Mateusz Dbkowski ᠌

Excellent oil, I have been using it for a long time, the quality has never been in doubt. But this is if the oil is changed in a large service center with a solid reputation. If you take it in ordinary, especially online stores, it is easy to run into a fake. The manufacturer came up with a kind of QR code to protect against fakes. I don't understand the meaning of this QR code at all. I have a can of oil already used a year ago, and this QR code is still making its way on the site. Those. if you wish, you can make thousands of such stickers, and they will show the "legality" of the product. It was necessary to limit the number of views of this code, for example, 10 times, or as an excise tax on alcohol, I bought it - and the code is no longer valid.
