Many of our diesel cars are fitted with an advanced emissions control system which helps the vehicle comply with the latest Euro 6 exhaust gas regulations. The addition of AdBlue® allows for far-improved MPG returns, so this cost is more than off-set by the reduced costs in diesel.

​

What is AdBlue®?

​

AdBlue® is a fluid that is sprayed into a diesel vehicle’s exhaust system to reduce the nitrous oxide emissions of diesel engines. AdBlue® is created by mixing urea and deionised water. The use of AdBlue® has increased in recent years since the introduction of stricter emissions standards in 2016.

​

How Does AdBlue® Work?

​

AdBlue® is stored in a separate tank to the fuel and works by injecting directly into a specially modified part of the vehicle’s exhaust. This then starts a chemical reaction that converts the polluting oxides of nitrogen into harmless oxygen and nitrogen; a process known as Selective Catalytic Reduction (SCR) which now allows for many diesel cars to be under the regulated emissions and be road legal.

​

How Often do I Need to Top Up my AdBlue®?

​

Your AdBlue® will be topped up during your regular servicing, however it may be that you will need to replenish the AdBlue® in your diesel vehicle in between services. It can be purchased from most fuel stations and some supermarkets. Cars that need AdBlue® in order to work will have a gauge on the dashboard to monitor the levels in the tank and will often display warnings when more is needed.

 

TCH Leasing will pay for the AdBlue® top ups that are within your scheduled service visits, however, it will be the driver’s responsibility to arrange the top up outside of servicing.

​

What Happens if my Car Runs Out of AdBlue®?

​

If your car’s AdBlue® runs out, you will notice a reduction in power and performance which will lead to the car simply not starting as the tank is dry. The AdBlue® will need to be replaced before the car’s engine will be able to start again.

 

It is important that the levels of AdBlue® are monitored correctly as, according to the AA, 23,000+ breakdowns have been linked to the misuse of AdBlue® in diesel cars.
