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.

Who is responsible for AdBlue?

It is the responsibility of the driver to ensure AdBlue is kept topped up and to pay any costs associated with doing so.

Days Fleet treat AdBlue as a consumable, similar to fuel and does not form any part of a maintenance contract unless specifically agreed.

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

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.

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.

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.
