AdBlue crystallisation is an inconvenient problem for many people, particularly those driving in colder climates or conditions.
When AdBlue crystallises, it can have terrible effects on your vehicle and its ability to run as it should. So, it’s essential to know where to source it from and how to store it correctly to ensure it performs effectively. Keeping up with maintenance and spotting signs of trouble will prevent costly problems from transpiring.
With prevention in mind, we’ve set out all the advice you need to avoid AdBlue crystallisation below to keep your life as stress-free as possible.
But before we start, here’s an overview of this planet-preserving solution.
What is AdBlue?
AdBlue is an aqueous urea solution used in diesel vehicles to reduce the emissions of nitrogen oxides (NOx). The urea in AdBlue reacts with the NOx in the exhaust gases to form harmless water and nitrogen. AdBlue is much friendlier to our planet and helps minimise the number of harmful solutions released into our environment.
What causes AdBlue to crystallise?
When AdBlue freezes (typically occurring at temperatures below -10°c), the solution can turn into a solid mass, causing it to clog up the system and prevent vehicles from starting. In extreme cases, this can damage your diesel engine beyond repair.
Crystallisation in Adblue can happen for various reasons, but it’s commonly down to either temperature changes or poor storage conditions.
How to prevent Adblue from crystallising
When your vehicle breaks down, it can considerably impact your day…not to mention your finances. You’ll be pleased to know that there are several ways to prevent AdBlue crystallisation, so let’s dive into some top tips to minimise the chances of damaging your vehicle.
Purchase AdBlue from a reputable source
Buying AdBlue from the right place will ensure that the solution is of good quality and that it’s been stored correctly. When AdBlue has been stored in the right conditions, it dramatically reduces the risk of it crystallising over time.
If you’re buying from an online retailer, consider looking at customer reviews, this will help you choose a reputable brand. When buying in-store, ask any questions you have about the product. This will give you confidence in finding the right solution for your engine type.
Try to keep your AdBlue tank full
Keeping your AdBlue fuel tank full will help insulate the solution and prevent it from freezing. Many modern cars will alert you when your AdBlue needs to be topped up, so keep a close eye out.
Remember, depending on your car model and how frequently you drive; you can expect AdBlue consumption to vary.
Another factor that can impact this is the weather condition outside of the vehicle. When it is cooler, you will naturally consume more AdBlue to prevent crystallisation from occurring.
