3x Anti-Crystal AdBlue Additive - 100ml

Liqui Moly AdBlue Additive / DEF System Protector is an ash-free formula designed to prevent faults in SCR systems by reducing deposits in the AdBlue® tank and injection system. It improves low-temperature performance and ensures finer atomization to help prevent crystallisation. This enhances system reliability and efficiency over time. Dosage: add 1% (100ml treats 12–15L of AdBlue®). For use only in AdBlue® systems – do not add to fuel.

Frost sensitive. Shake at room temperature to disperse deposits on the bottom.
