Extralube ZX1 Micro Oil Treatment.
Has anyone any feelings about this stuff? My Skoda is almost 25 years old, and has just passed 45k on the clock.
There are loads of internet articles that are either 100% for or 100% against.

Extralube ZX1 Micro Oil Treatment is a metal treatment which chemically bonds to the metal surfaces, modifying the friction surfaces of the metal so the oil can do its job better. The result is lowered carbon exhaust emissions, increased mpg, excellent cold start protection and anti-wear performance.
