How do I add AdBlue to my car and how much do I put in?
729 Views
Many modern diesel cars are fitted with Selective Catalytic Reduction (SCR) systems to reduce harmful nitrogen oxide (NOx) emissions. These systems rely on a special liquid called AdBlue, which is injected into the exhaust stream and reacts with the NOx to convert it into harmless nitrogen and water vapour.
For DIY enthusiasts who maintain their own vehicles, topping up the AdBlue tank can be a straightforward task. However, understanding how much AdBlue to add and the correct topping-up procedure is crucial.
How to add AdBlue to your car
Adding AdBlue to your car is a simple process that you can easily do yourself. The first step is to locate the AdBlue tank in your car. You can usually find it next to the fuel tank or in the engine compartment, but this can vary depending on the make and model of your car. Once you've located the AdBlue tank, remove the cap and carefully pour the fluid into the tank using a funnel to avoid spilling. Remember, keeping dirt and debris out is key, so be careful not to let anything unwanted enter the tank as you pour in the fresh fluid.
How much AdBlue should I put in my car?
The amount of AdBlue you need to add to your car depends on the size of your AdBlue tank and the vehicle's mileage. Most cars use between 0.5 and 1.5 litres per 1,000 kilometres (or 621 miles) driven.
This, in turn, will help your car comply with emissions regulations and avoid the potential cost of a catalytic converter. Keeping an eye on and maintaining AdBlue levels not only ensures the SCR system's efficiency but also helps avoid costly catalyst repairs.
Additional considerations:
High-quality AdBlue is essential for optimum SCR system performance, as contaminated or impure fluids can damage the catalytic converter and reduce emission control efficiency. Given the catalytic converter price, the use of clean AdBlue becomes even more critical to prevent avoidable damage.
AdBlue has a typical shelf life of approximately 12 months. Avoid storing large quantities and check the expiry date on the container before use.
AdBlue is readily available at petrol stations, auto parts stores, and online retailers. The Adblue price can vary depending on the brand and quantity purchased.
If your car is experiencing problems with the SCR system, such as a faulty injector or a blocked DPF (e.g. Ford Kuga DPF filter), this can lead to increased AdBlue consumption.
Can I top up AdBlue at any time?
It's important to check the fluid level regularly and top up if necessary to ensure the SCR system continues to operate properly. How often you need to add it will depend on your driving habits and the size of your AdBlue tank, but a good practice is to check the level every time you refuel your vehicle.
