AdBlue is a def (diesel exhaust fluid) which assists in reducing the harmful nitrogen-oxide emissions that are produced by diesel engines.

A colourless non-toxic liquid AdBlue is fundamentally made up of a water and urea, in this instance, the urea is a remarkably pure, and of a much higher grade

than that commonly found in glue, fertilisers or cosmetics. the water that is used is de-mineralised, which is cleaner than what comes out of a regular tap. The introduction of this clever but simple chemical is to aid car manufacturers in combating the ever-stricter emission targets.
