Protect your SCR system against crystallization

BARDAHL OptiBlue is an additive specially developed to prevent crystallization in your car's AdBlue system. By adding OptiBlue to your AdBlue, the SCR system stays clean and functions optimally.

Increase the efficiency of your AdBlue

This additive stabilizes and improves the efficiency of AdBlue, which is especially useful during longer storage periods. It lowers the surface tension of AdBlue, resulting in finer atomization and an optimized operating temperature of the SCR system.

Prevent costly repairs

By preventing urea crystallization, OptiBlue protects the AdBlue injectors from blockages and wear. This helps to avoid expensive repairs and vehicle downtime.

Suitable for all diesel engines with SCR system
