The frequency of AdBlue top-ups depends on your driving habits and vehicle type. Typically, you’ll need a top-up every 3,000 to 12,000 miles. Your vehicle will notify you when AdBlue levels are low with a dashboard warning light.

If you run out of AdBlue, your vehicle may enter limp mode, which reduces engine performance. In some cases, the engine may not restart until AdBlue is topped up, so it’s important to refill as soon as the warning light appears.

Yes, you can top up AdBlue yourself, as it's sold in many car shops and petrol stations. However, it’s important to use the correct AdBlue fluid and avoid spilling it. For convenience and accuracy, we recommend having a professional top-up at QCD Autocentre Brackley.

No, AdBlue is stored in a separate tank and is not mixed with diesel fuel, so it does not affect fuel consumption. Its sole purpose is to reduce harmful emissions from your vehicle’s exhaust system.

Yes, most modern vehicles equipped with AdBlue systems will display a dashboard warning light when AdBlue levels are low. This warning will give you ample time to top up before the system runs dry.

Running out of AdBlue won't cause direct damage to the vehicle, but it will force the engine into limp mode or prevent it from starting, as the system is designed to meet emissions standards. However, continued low levels of AdBlue can strain the emissions system over time.

The amount of AdBlue your vehicle needs depends on its make and model, as well as your driving habits. Typically, most vehicles require around 4 to 10 litres per top-up.

Yes, AdBlue is specifically used in diesel vehicles equipped with a Selective Catalytic Reduction (SCR) system to reduce harmful nitrogen oxide (NOx) emissions.
