How to prevent Ad blue system issues with crystallization? Ad blue crystal build up can cause various problems within in vehicle. Including more than just the Ad blue system. It can create engine damage, decreased fuel efficiency, and even complete system failure. So how can we prevent issues from arising?

Firstly its important when topping up your Ad blue to make sure you don’t spill the liquid. The entry point can vary between cars. Sometimes its above the fuel cap which is relatively accessible other times in can be in the boot which is much more difficult. If you spill the Ad blue it can crystalize around the area and ruin paintwork.

So why does Ad blue crystalize in the tank?

Usually Ad blue crystalizes due to temperature changes and poor storage conditions. Therefore it is imperative to source your Ad blue from a reputable supplier. It also helps to keep your Ad blue tank fully topped up. This helps to keep the solution insulated. It also helps stop crystallization from occurring on the walls of the half empty tank. There are people who want to advise taking apart the system and tank. However, this is a very labour intensive job as well as potentially affecting the many sensors in the area. We would advise using an Ad blue additive, we use Tunap 988. This product reactions with the urea to reduce the amount of crystals forming in the system.

There are people that get around Ad blue issues by having the feature mapped out of the vehicle. This is strongly advised against as it can cause further issues within the vehicle. 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.

Its also essential to keep up with general maintenance and service requirements. By following these steps and practicing regular maintenance, you can keep your vehicle running smoothly and reduce emissions, all while ensuring a longer lifespan for your diesel vehicle.

Our brake fluid servicing starts at £55 with the option to upgrade to Millers Oils Racing Brake Fluid.

We recommend carrying out a brake fluid service every 2 years, regardless of mileage. This is a preventative measure to ensure the correct running of your vehicle. Brake fluid is hygroscopic, which means it attracts moisture. As you can imagine that does not do your vehicle any favours. With many parts of the braking system being metal. It can lead to corrosion of the metal components if not regularly maintained.

Over time the brake fluid also becomes contaminated with metal particles, reducing the boiling point of the fluid and in turn reducing the braking power of the car.

The upgrade to using Millers Oils is beneficial as the it has a dry boiling point of up to 310 degrees. As opposed to the standard fluid minimum of 230 degrees. This in turn provides exceptional resistance to vapour locking and good compressibility for an improved brake feel. Brake fluids play a key role in driver experience and vehicle feedback. Therefore Millers Oils motorsport brake fluids maintain their viscosity even at high temperature and are robust against water absorption to ensure consistent performance.

Upgrade to Millers Oils for an extra £25.
