Diesel Exhaust Fluid: The Facts

19 July 2016 By Steve Sefton, Energy Category Buyer

Diesel Exhaust Fluid

Did you know you can compliantly buy Diesel Exhaust Fluid (DEF) using YPO’s Liquid Fuels Framework? Badged in Europe as AdBlue, it’s used in many heavy commercial diesel powered vehicles to reduce emissions of nitrogen oxides from the exhaust of these vehicles.

We receive lots of customer questions regarding AdBlue, as it’s relatively new to some customers. The impact of Brexit has also created further questions. With this in mind we’ve worked with Certas to put together some facts that you may find useful.

Do I need AdBlue?

If you use a modern diesel powered commercial  vehicle fitted with a Selective Catalytic Reduction (SCR) system, you may need AdBlue. Since 2005, newly built Euro 5 trucks and buses are fitted with an SCR system. AdBlue is used in order to comply with strict European standards and since 2015 all Euro 6 vehicles require AdBlue.

What is AdBlue made from?

It’s a pretty harmless substance, made from a mixture of 32.5% high purity synthetic,  AUS32, urea  and 67.5% deionised water.

Is AdBlue hazardous?

As it’s made from water and synthetic  urea - and when used in line with manufacturer’s guidelines - it is safe to use. Small spills can be easily rinsed away with water. It has no known environmental dangers.

Can you mix AdBlue with the Diesel?

This is a definite no no! AdBlue has a dedicated tank of its own in the vehicle and if diesel is inadvertently mixed with the AdBlue this will result in a potentially expensive repair job and could invalidate warranty.

How should AdBlue be stored?

AdBlue is non-flammable and non-explosive  but it’s highly corrosive to base metals therefore only dedicated AdBlue  storage and dispensing systems should be used. It should be kept out of direct sunlight  below  +38C  or above – 11C.

How will Brexit affect the use of AdBlue?

European law will remain in place while the Government negotiates the terms of the EU exit. The use of AdBlue will likely remain a legal requirement for at least two years and there’s a very good chance that the use of AdBlue will be incorporated into future UK environmental legislation.

Where can I buy Adblue?

Through YPO’s Liquid Fuels framework! YPO can source quality AdBlue which meets ISO22241. Further competitions can be run if required by YPO to ensure you get the best rates. Please contact Steve for further information email: [email protected] or call 01924 834867.
