Your guide to AdBlue

Posted Posted on Categories Business NewsTags

From September 2015 all new vehicles sold in the EU must be compliant with Euro 6 emission standards. As a result, the majority of new diesel cars and LCVs will contain a factory-fitted AdBlue® injection system which neutralises most of the harmful NOx emissions.

What is AdBlue?

AdBlue® is a high purity, manufactured solution which is pumped to the diesel engine where it is injected into the exhaust gases.

It must be used in a dedicated tank on the vehicle, which should just be refilled as and when required. AdBlue® is non-flammable and non-explosive. It is classified as a transportable fluid with minimal risk.

For some fleets the use of AdBlue® is not new, buses and heavy goods vehicles have been using it for several years.

How will I know what my current level of AdBlue® is?

Diesel vehicles using AdBlue® are equipped with special dashboard warning lights to indicate when a refill is needed.

Drivers will need to pay attention to this warning.

How often does AdBlue® need to be topped up / replaced?

AdBlue tank capacities vary from model to model and the more economically a vehicle is driven, the less AdBlue® will be used.

A typical vehicle with a full tank of AdBlue® will last approximately 9,000 miles before requiring a complete refill, depending on driving style and conditions.

What will happen if I run out?

It is important that levels of AdBlue® are maintained as the vehicle will not start if the tank ever runs empty.

How do I refill the AdBlue® tank?

AdBlue® must only be poured into the vehicle’s dedicated tank (typically located next to the diesel fuel tank – refer to your handbook for the exact location) and must not be put into the diesel fuel tank. AdBlue® must not be mixed with any additives or diluted with water.
