AdBlue FAQS 1-10:

Question 1: what is AdBlue?

AdBlue is a liquid solution of urea (a component of synthetic urine) and deionized water. It is completely colourless and non-toxic. It was introduced to neutralize nitrous oxide emissions from diesel engines in line with government targets.

Question 2: what does AdBlue do?

AdBlue neutralizes exhaust gases produced by diesel vehicles.

Question 3: how does AdBlue reduce pollution?

AdBlue produces a chemical reaction when injected into the exhaust system of a diesel engine. This chemical reaction neutralizes the harmful nitrous oxide emissions produced by diesel vehicles. This tackles air pollution by reducing exhaust emissions and enhancing air quality.

Question 4: why does my car/vehicle need AdBlue?

Your vehicle needs AdBlue to reduce nitrous oxide emissions. This requirement is in line with stricter emission legislation, which aims to neutralize exhaust gases from diesel engines to help the environment.

Question 5: how much AdBlue do I need?

It is vital that you use licensed AdBlue because AdBlue that is the incorrect specification will damage your vehicle and prove costly.

Question 6: who uses AdBlue?

AdBlue is used by anyone who has a modern diesel vehicle.

Question 7: how can I check if my vehicle needs AdBlue?

If you have a black or blue cap adjacent to your main fuel cap, then your vehicle requires AdBlue.

Question 8: how much AdBlue do I need?

The amount of AdBlue you need will depend on the type of vehicle you have. If you are running a car, then a 10L will be sufficient for a refill. If your vehicle is a coach or a truck, you would benefit from purchasing a larger volume from an IBC or a barrel.

Question 9: what happens if I run out of AdBlue?

If you run out of AdBlue, your vehicle will go into limp mode. Most vehicles require a minimum amount to be refilled before the engine will start again.

Question 10: how do I check the AdBlue level in my vehicle?

Most vehicles will display a warning sign or notification which will notify you if you are low on AdBlue. To check the AdBlue levels manually, consult your owner’s documentation or contact the vehicle manufacturer for guidance.

AdBlue FAQS 11-16:

Question 11: how long can I store AdBlue?

AdBlue lasts up to 18 months if it is kept out of direct sunlight and below 25C. However, when AdBlue is stored at a higher temperature or in direct sunlight, it will expire after 6 months.

Question 12: how can I keep AdBlue fresh?

Contaminated AdBlue can damage your diesel vehicle’s engine system and prove ineffective at reducing exhaust fumes. Fill your vehicle’s AdBlue tank as quickly as possible to avoid contamination and keep the AdBlue container firmly closed between refills. If there is debris in your AdBlue container, dispose of the AdBlue and container and purchase a new one.

Question 13: how do I fill my car with AdBlue?

Remove the cap to the AdBlue tank, (which will be either a blue or black cap adjacent to your fuel cap), and dispense the liquid carefully into the tank from its container. Do not put AdBlue in your fuel tank, as it is not a fuel additive.
