Make sure that you never reuse any spilt AdBlue as it will have become contaminated. This will cause expensive damage to your vehicle’s SCR system. Is AdBlue an additive to diesel?

AdBlue is added to fuel appropriate to consumption. Usage is therefore affected by driving style, journey type, engine and vehicle load, and environmental conditions.This warning light means that you have about 1,500 miles of fluid left. You should look to fill up your tank as soon as possible to avoid it running out. AdBlue must never be added to fuel. If AdBlue is added via the fuel filler, you should not start the vehicle and immediately call the appropriate emergency support number. Maintained leasing contracts do not cover AdBlue costs. However certain lease providers will top up AdBlue as part of a routine service. AdBlue is used to reduce diesel exhaust emissions. It became compulsory for all diesel vehicles to use a form of DEF in September 2015 when the EU introduced Euro 6, their strictest emissions standard yet.

As well as reducing NOx without harming engines, TotalEnergies AdBlue® also features TotalEnergies ClearNOx, an additive within the solution that cleans SCR systems, improving their cold and stop-start performance. Reducing clogging in exhaust, ClearNOx has been shown to remove the risk of clogging for up to 50,000km and reduce maintenance costs. All commercial diesel-engine vehicles that weigh above 7.5 tonnes and vehicles manufactured after October 2006 (Euro IV and Euro V) are fitted with Selective Catalytic Reduction (SCR) technology. For SCR to function – and for the vehicle to function – AdBlue must be injected into the exhaust gases as a post-combustion process. How do I know if my car uses AdBlue? Your tank which holds white diesel fuel is not designed for AdBlue so make sure you don’t mix the tanks upThe technology that used AdBlue is known as selective catalytic reduction, or SCR. Despite only becoming widely used in diesel cars over the last few decades, it’s existed for a long time prior to that. The SCR process involves injecting precise amounts of a AdBlue liquid into the exhaust system and neutralising the harmful emissions in the exhaust gases by way of a chemical reaction. How does AdBlue work? Thankfully, topping up the AdBlue reservoir is easy and cheap. Our Halfords AdBlue 10l includes all the fluid you need and comes with a handy pouring spout to make refilling a doddle. If these don't bring you any answers - or the warning light persists - ask a professional mechanic for help.

Polluting chemicals and compounds, including Nitrogen Oxide and Nitrogen Dioxide, are produced when diesel engines burn fuel. These elements build up in the air and produce smog and acid rain.AdBlue is the generic marketing name for the product more technically known as diesel exhaust fluid. (image credit: Penrite) In the international standard defining DEF ( ISO 22241), it is referred to as AUS 32 (aqueous urea solution 32%). [5] DEF is also sold as AdBlue, a registered trademark of the German Association of the Automotive Industry.

Taking Audi as an example, a minimum of 5.7 litres of AdBlue is required to restart the vehicle, although this level varies between manufacturers.Urea is a compound that breaks down nitrogen oxides into nitrogen and water, and it’s also found in urine. The urea in AdBlue is manmade. While AdBlue isn’t classified as toxic, it could still cause environmental damage if allowed to run into a source of water, and it can also be an irritant if it gets on your skin or in your eyes. Can I refill AdBlue myself? AdBlue is not a hazardous substance and has no known effects or critical hazards. Urea is a raw material that also occurs naturally in our digestive system. However, we strongly advise that you never inhale or ingest AdBlue due to the risk of a reaction.
