## Description

Liqui Moly DEF Anti Crystal Additive Concentrate is an ash-free combination of additives that minimises malfunctions in the SCR system of diesel engines. It reduces deposits in the AdBlue® tank and the injection system, improves flow and reduces the risk of crystallisation. By lowering the surface tension of the urea solution, it makes the solution atomise finely.

It suits all SCR systems that run on 32.5% urea solution (AdBlue®, DEF) and is made for long-term use.

**Technical data**

- Dosage: 0.25% of the AdBlue® quantity (1:400)
- 250 ml treats 100 l of AdBlue®
- Volume: 0.25 l

**How to use**

- Add it to the AdBlue® tank, ideally after filling the tank.
- Do not add it to fuel.
- Because of the high concentration of active ingredients, foam may form under unfavourable conditions: check beforehand that it suits the components of the system.
- The concentrate is sensitive to frost: shake it at room temperature to disperse any deposit at the bottom.

**Safety**

- Causes serious eye damage.
- If medical advice is needed, have the product container or label at hand.
- Keep out of reach of children.
- Wear protective gloves, protective clothing, eye protection and face protection.
