What is AdBlue?
Adblue is becoming increasingly popular as the years go by, due to car producers needing to abide by strict environmental rules... but what is AdBlue?
AdBlue was created in order to reduce the nitrogen-oxide emissions that are largly produced by diesel engines. The fluid is non-toxic, non-flammable, odourless and biodegradable, and is made up with a solution of water and urea. The fluid has a separate tank from your diesel tank. Adblue allows diesel vehicles meet the Euro 6 exhaust emission regulations.
So... how does it reduce nitrogen-oxide emissions?
Cars built after 2006 use SCR technology, which injects small quantities of AdBlue into the exhaust of your car. When this solution is then combined with the emissions produced by diesel it breaks down the mono-nitrogen oxides, which then gets converted into water and nitrogen; which is harmless for our planet!
If your Diesel Vehicle runs out of Adblue it will fail to start. It's advised to NEVER ignore the AdBlue light that will appear on your dashboard when levels are low. However, you are able to re-fill the AdBlue yourself, if you know how to locate the AdBlue filler. On more modern models, it can be found next to the fuel filler cap. It may be a good idea to ask a salesman where it is, if you are buying a new car.
