## Description

Liqui Moly AdBlue anti-crystallisation additive is an ash-free additive combination that prevents faults in the SCR system of diesel engines. It reduces deposits in the AdBlue® tank and the AdBlue® injection system. By lowering surface tension, it makes the urea solution atomise very finely. It optimises the AdBlue® return flow and so lowers the risk of AdBlue® crystallising. AdBlue® is a registered trademark of VDA Verband der Automobilindustrie e.V. (Berlin, Germany).

The additive comes in 250 ml and 2.5 L packs.

**Usage**

Add 0.25 % (1:400) to the AdBlue® solution:

- 25 ml treats 10 l of AdBlue®.
- 250 ml treats 100 l of AdBlue®.
- 2.5 l treats 1000 l of AdBlue®.

It is meant for long-term use. Do not add it to fuel. Add it to the AdBlue® tank after filling. Because of the high concentration of active ingredients, foam may form in unfavourable conditions, so check the compatibility of the parts first.

Liqui Moly is a German maker of lubricants and additives based in Ulm, known above all for its engine oils and engine additives.
