How to prevent AdBlue crystallization

Model: (Various brands) Various
Part: Checks and maintenance

In this video, we are advised on a system to prevent the crystallization of AdBlue, which occurs especially if our Diesel car remains stationary for even a short period of time. It is always better to be proactive and anticipate the problem by adding an additive to the AdBlue that prevents the issue, as recommended by the YouTuber. This additive is SintoFlon AdClead, which can be found for example on eBay with the code 154750588386 at a price of 25.82 euros, with free delivery. Just add 25 ml for every 10 liters of AdBlue: so a 250 ml bottle is enough for 100 liters of Urea.
