Is it possible for AdBlue additive to be of poor quality? Unfortunately, yes, and it is very easy for this to happen. First of all, we need to know that urea and sunlight do not get along at all: stagnant AdBlue stored under the July sun is destined to have poor quality because urea is destined to decompose.

On the other hand, too low temperatures can also damage it, as they can cause it to crystallize. It is also very sensitive to contamination, so even a small amount of dirty water, oil, or fuel can permanently damage its quality.
