When added to fuel, it improves fuel flow in cold climates (prevents fuel from freezing, depending on fuel quality, down to -31°C), keeps fuel injectors clean, ensuring fuel combustion with more efficient combustion and less smoke. Significantly improves fuel vaporization properties, cleans the fuel system and increases cetane number. Protects the fuel system from water "intake", having a strong demulsifying effect that removes water from the fuel.

Usage:
Add to fuel at a minimum of +5°C, the additive does not mix with frozen fuel, store the package at + temperatures. 
250ml is enough to treat 150L of fuel.
