10 facts about Adblue, the chemical you add to your diesel car to make it cleaner. So here’s some facts about Adblue and an overview about what is Adblue?

Facts about Adblue.

1: Contrary to the name, Adblue is not actually blue.

AdBlue is actually a clear liquid and looks like slightly yellow water. Doesnt smell like water though!

2: Adblue is actually urea, that’s pee to you and me.

It’s actually 67.5% deionised water and 32.5% urea. Hence why it smells like babies nappies.

3: The reason your car needs AdBlue is to reduce emissions.

To meet Euro 6 emission controls to be exact. The way AdBlue works is it’s sprayed into the Catalyst in your car’s exhaust to reduce emissions. The Adblue causes a chemical reaction in the catalyst with the nitrogen oxide and nitrogen dioxide and this chemical reaction changes the NO and NOx into water vapour and nitrogen.

4: If you own a car which requires AdBlue the solution must be bought and paid for by you.

To use Adblue there is an additional fluid tank which needs to be filled at regular intervals (how long depending on the size of the tank). Typically 1L of AdBlue is needed per 650 miles approximately. The cost for this is roughly £1.40 per litre however your vehicle dealer may charge significantly more for this.

5: If your vehicle uses AdBlue and you run out, it will stop working.

The emmisons control systems on the vehicle will know if AdBlue is not present in the system (typically you’re warned when down to the last few litres (AdBlue tank size dependant)).

6: It’s injected into your vehicles exhaust and not mixed with your fuel.

Although on some cars the AdBlue filler is next to the diesel cap the tank is separate and adding AdBlue to your diesel would be an expensive mistake. The AdBlue is injected into your cars exhaust after the diesel is burnt.

7: Some vehicles are easier to fill with Adblue than others.

Depending on the model of vehicle that you own depends on how easy it is to actually fill your AdBlue tank. Some manufacturers put the AdBlue filler beside the fuel filler where as other vehicle manufacturers put the tank under the boot floor in your car. my Mercedes E-class has the tank under the boot floor which also means no spare wheel.

8: Its also know as Diesel Exhaust Fluid (DEF) or Aqueous Urea Solution.

Adblue is standardised as AUS 32 (aqueous urea solution) in ISO 22241 and is also known as Diesel Exhaust Fluid.

ISO 22241-1:2006 specifies the quality characteristics of the NOx reduction agent AUS 32 (aqueous urea solution) which is needed to operate converters with selective catalytic reduction, so-called SCR (Selective Catalytic Reduction) converters, in motor vehicles with diesel engines. SCR converters are particularly suitable for selectively reducing the nitrogen oxide (NOx) emissions of diesel engines.

9: AdBlue is a virtually harmless substance.

AdBlue is a non-flammable and non-explosive liquid. Classified as a minimal risk, transportable fluid. If you spill AdBlue on your hands or cloths then throughly wash with plenty of water. The use of protective gloves is recommended to prevent an irritation.

10: And the final facts about Adblue, it makes no difference to the power your engine produces

Really, it doesn’t. All its designed to do is to make your diesel emissions cleaner from your exhaust and no claims are made that it will increase the power of your engine.
