Actually it's not 'fake'. X1R was actually designed originally for NASA as a high friction lubricant. It is used in many performance applications. However, bear in mind that your car was designed to take a specific viscosity (thickness) of oil. So adding this product may reduce that viscosity, resulting in a smoother engine but less protection. Not following your manufacturer recommendation for oil is particularly hazardous for turbo application as the oil has to go through small hoses and pipes so you want to have an oil that's of consistent thickness.

Tldr: If you don't know what it is, don't use it.
