What is AdBlue?

AdBlue is a Diesel Exhaust Fluid (DEF) that helps reduce harmful emissions produced by diesel vehicles. It is made of urea and deionised water and interrupts chemical reactions within your exhaust system.

While your car's engine is running, tiny amounts of AdBlue are squirted into the exhaust. These react with the harmful Nitrous Oxide (NOx) gases, turning them into Nitrogen and water. It works alongside your Diesel Particulate Filter (DPF) to reduce NOx emissions by up to 90%!

Why should I book an AdBlue top-up?

Your car will not run without AdBlue. It's as integral as diesel. This means your car will enter 'limp home' mode if you run out of AdBlue, reducing engine power and performance to limit emissions. This can cause untold stress and uncertainty as you plot how to get home. If you don't know how much DEF your vehicle has, book an AdBlue top-up with BookMyGarage now!

AdBlue is a legal requirement than became standard in 2015. This is to help all diesel cars meet the strict Euro 6 emissions regulations. Every year, there are 40,000 pollution related deaths in UK cities! Don't contribute to this problem. Book an AdBlue top-up and DPF flush now to reduce your vehicle's emissions level.

A lack of AdBlue can also lead you to fail the strict emissions test that has been part of your MOT since 2018. Don't be part of the 240% rise in emissions MOT failures among diesel vehicles. Book your AdBlue top up now.

When should I book an AdBlue top-up?

On average, 1 litre of AdBlue will last you 600 miles. The average AdBlue tank on diesel cars is about 10 to 11.5 litres. This means a full tank of AdBlue should last you at least 6,000 miles.

There is an AdBlue warning light which illuminates when you have 1,500 miles of DEF left. We recommend booking an AdBlue top-up near you when you see this warning light. Running out of AdBlue can lead to severe problems.
