what does adblue do

AdBlue is a diesel exhaust fluid used in many modern diesel vehicles to cut harmful emissions. It works in the exhaust system to turn nitrogen oxides into nitrogen and water , which are much less harmful.

Quick Scoop

AdBlue is not a fuel additive ; it goes in a separate tank in vehicles that use Selective Catalytic Reduction, or SCR technology. It is commonly found in Euro 6 diesel cars and vans , especially models registered from September 2015 onward.

What it does

• Reduces NOx emissions from diesel exhaust.

• Helps vehicles meet strict emissions rules.

• Converts pollutants into harmless water and nitrogen.

What to know

• AdBlue is typically colourless, non-toxic, and biodegradable.

• If you run out completely, many cars will not start until it is refilled.

• It is used only in diesel vehicles with the right emissions system, not in every diesel car.
