AdBlue tank in a diesel vehicle

What is a diesel exhaust fluid?

Diesel exhaust fluid is widely known as AdBlue, however it can be bought from many other brands.

Diesel exhaust fluid is a liquid solution made up of urea and deionised water, used in diesel engines with selective catalytic reduction (SCR) technology to reduce harmful emissions. The SCR system can reduce nitrogen oxide emissions by up to 90%.

AdBlue is not a fuel additive and should not be mixed with diesel fuel. It is stored in a separate tank.

Vehicles that need diesel exhaust fluid

Diesel exhaust fluid is required by law in many countries for diesel-powered vehicles that use selective catalytic reduction (SCR) technology to meet emissions standards. This includes:

- heavy-duty trucks and buses
- some passenger cars and SUVs with diesel engines
- agricultural and construction equipment with diesel engines

It is important to check your vehicle's manual or consult with a dealer to determine if your vehicle requires diesel exhaust fluid.

What does diesel exhaust fluid do?

Diesel exhaust fluid is essential for the proper functioning of the SCR system, which reduces vehicle emissions and therefore ensures compliance with emission regulations.

What happens when you don't use diesel exhaust fluid

If you do not fill the tank, the SCR system will not function properly and your vehicle will not comply with emissions regulations. This can result in fines and other penalties. Additionally, your vehicle may experience reduced performance or even shut down if diesel exhaust fluid tank is not filled.

When should the AdBlue tank be refilled?

The AdBlue tank typically needs to be refilled every 5,000 to 10,000 miles, depending on the vehicle.

To avoid any issues with the SCR system and ensure compliance with emissions regulations, it's recommended to keep track of the AdBlue tank's level and refill it as needed. Many newer vehicles have a dashboard warning light that will indicate when the AdBlue level is low and needs to be refilled.

If you're unsure about how often your vehicle's AdBlue tank needs to be refilled, it's best to consult your vehicle's manual or speak with a dealer.
