If you own a Land Rover that was manufactured in 2016 and beyond, then you’ve probably heard of AdBlue before. However, there’s every chance you don’t really understand what it is, despite the fact your car needs it.

So, allow us to explain what AdBlue is, how it works, and the benefits it can bring…

What is AdBlue?

AdBlue is the trademarked product name for Diesel Exhaust Fluid, and it’s essentially a type of fluid that’s stored in its own tank within your car. It’s completely non-toxic, there’s no colour to it, and it doesn’t have a scent. You might have seen containers of this fluid sold outside petrol stations all over the country - it’s an essential item for anyone with a diesel engine car.

How does it work?

This is where things get very technical as there’s a lot of science involved in AdBlue. Essentially, you have a dedicated tank with this solution inside, and your car automatically injects it into part of your vehicle’s exhaust system. This is done on regular intervals, and you don’t have to do anything other than ensure your AdBlue levels aren’t too low.

When this solution enters the exhaust system, it has one clear aim; to clear up the harmful exhaust gases. When the liquid goes into your exhaust, it releases something called ammonia, which helps set off a chemical reaction. The dangerous Nitrogen Oxide gas gets converted into Nitrogen and water vapour. Both of these things are entirely harmless to the atmosphere, which essentially means you clean up your emissions.

This whole process is known as Selective Catalytic Reduction or SCR for short. All Land Rovers from 2016 to now are fitted with special SCR technology which allows them to use AdBlue and clean their exhausts.

What are the benefits of AdBlue?

The most obvious benefit is that it allows car owners to reduce their emissions by naturally getting rid of toxic exhaust fumes. In fact, it means that Land Rover can actually meet the EU6 emissions legislation by lowering nitrogen oxide by up to 90%.

As such, if you own a Land Rover with SRC technology, then you have the benefit of being an eco-friendlier driver than a lot of other people out there. Plus, one of the great things about AdBlue is that it works without you having to do anything. There’s no need to adjust your driving style or manually feed it through your exhaust; it’s all done by your car’s technology. The only thing you have to worry about is if your AdBlue levels need to be topped up, but your car will notify you of this as you’re driving.

In summary, AdBlue is a liquid solution that’s fed into the exhaust system of your diesel engine to clear up nitrogen oxide emissions. It’s known as one of the best and most effective ways of lowering emissions, and all Land Rover’s with a model year of at least 2016 are fitted with the technology to make use of it. If you need a mid-service top-up of your AdBlue, then we’re offering them for the small price of £29.99.
