Viscor New Formula is a calibration fluid used in the process of tuning fuel pumps and injectors in diesel engines. In addition to very constant and accurate density and viscosity, Viscor NF contains a sophisticated package of additives, which provides the following properties:

  • Tuning within clearly prescribed values, as a result of which it is possible to tune the diesel injection systems in a reproducible manner
  • Very high resistance to corrosion: pumps and injectors can be stored in the warehouse without any problem after tuning
  • Viscor NF protects parts from rust and corrosion.
  • Fuel saving
  • Improved exhaust gas emissions: improved combustion is possible due to effective tuning, which benefits the environment


Viscor NF is a calibration fluid used in the process of tuning diesel injection systems. Furthermore, after these systems have been tuned, the product is suitable for use as a preservative fluid for components being placed in storage.
