A brief guide to Adblue

What is AdBlue?

AdBlue is a non-toxic fluid which helps reduce the nitrous oxide emitted in diesel exhaust fumes. This formula is a diesel fuel additive which is stored in a separate tank to your diesel and is sprayed onto the fumes before they leave the exhaust pipe. Once applied to the fumes, the AdBlue solution neutralises the harmful emissions before they’re released into the atmosphere.

All AdBlue needs to meet ISO 2241 specifications, as set out by the German Association of the Automobile Industry (VDA), who currently hold the official trademark. AUS32 and diesel exhaust fluid are two other terms used to refer to AdBlue. It is made from 67.5% deionised water and 32.5% high-purity urea.

How is AdBlue used?

The nitrous oxide within exhaust emissions from diesel engines are broken down by using the SCR procedure, which requires the use of diesel exhaust fluid. Carbon dioxide and ammonia are formed when AdBlue mixes with the exhaust emissions. The volume of exhaust fluid used is approximately 2% of the diesel usage itself. Diesel exhaust fluid is stored in a separate container on large vehicles. The ammonia formed is broken down into nitrogen and water and released through the exhaust, which is harmless to our environment.

Is AdBlue safe to handle?

Care should be taken when storing and transporting AdBlue as some metals can corrode if they come into contact with the fluid. If you need advice on storing and dispensing the product then a member of our team will be happy to help. However, we do recommend keeping exhaust fluid away from direct sunlight in a well-ventilated area that is dry and cool.
