The method is as follows:

1. Use any query software to scan the QR code. If it fails to jump to the confirmation page after scanning, it means the engine oil is fake.

2. If the engine oil bottle cap is equipped with a recessed "Mobil" trademark, and the silver aluminum foil on the bottle mouth is completely sealed, and there is a QR code authenticity identification mark on the bottle, the engine oil can be confirmed through packaging anti-counterfeiting technology of authenticity.

3. Next to the touch-sensitive QR code are colorful sequins with a concave and convex feel; use your mobile phone to scan the QR code to compare whether the distribution of sequins matches; you can pick out the sequins to complete the authenticity identification.
