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.
Clean the AdBlue pump and pipeline regularly
In order for AdBlue to work correctly and not crystallise, you need to maintain its pump and pipeline; this means cleaning these areas once the ignition has been turned off. Proper emptying of the pipeline is the primary way to prevent any problems from occurring, including crystallisation.
We suggest getting in the habit of cleaning the pump as often as needed; trust us, your future self will thank you; it will also help you get the best use out of your AdBlue product since there will be far less wastage.
Keep your AdBlue in a warm storage place
If you can, store your AdBlue in a warm garage. This is the best way to keep the solution efficacious and in optimum condition. However, where this isn’t possible, you can wrap the tank in an insulating material which will help to retain heat.
Many people overlook where they store products for their vehicle, resulting in solutions drying out or freezing. Save money and time by keeping your AdBlue solution in the right environment.
