A serious side effect of AdBlue: crystallization.

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

In this video, the YouTuber shows us, with a very simple example, the effect of a minimal amount of AdBlue on a metal dish. By leaving it there for about forty-eight hours, we will find that the liquid has completely crystallized, leaving the dish looking as if it is covered by a small glass sheet; this effect also occurs in our tank: let's be clear, it does its job excellently, which is to reduce NOx emissions, and one way to avoid this problem is to never let the tank run completely empty. Additionally, we can add an anti-crystallization additive, which we can find, for example, on Amazon with the code B09LQX33Z8, priced at 24.50 euros, with free shipping.
