In this video we’ll show you:

• The process for refilling with AdBlue

What is AdBlue, and why does a vehicle need it?

AdBlue is an additive composed of distilled water and urea. It’s specifically used in exhaust systems to reduce various Oxides of Nitrogen which can be harmful. It can also be called Exhaust fluid.

How much AdBlue does a vehicle need?

It all depends on the make and model of the vehicle. For example the Urea tank on a MK4 Skoda Octavia is 12 liters. Be sure to check the manufacturer’s guidelines or the vehicle handbook to be sure.
