What is AdBlue?

In this article, we provide detailed information about AdBlue, a term frequently heard in diesel engine vehicles, and answer the questions you may have. If you do not own a new diesel vehicle or if your car is gasoline-powered, you may not yet be familiar with AdBlue. Today, many new diesel vehicles come pre-filled with AdBlue, and many of the cars you rent from Avis Filo also include this feature.

What is AdBlue Used For?

AdBlue is a urea and purified water solution used in diesel vehicles to reduce nitrogen oxide (NOx) emissions and prevent the release of harmful gases into the environment. It consists of 32.5% purified urea and 67.5% deionized water. The size of the AdBlue tank varies depending on the vehicle model.

How Does AdBlue Work?

AdBlue works with Selective Catalytic Reduction (SCR) technology to convert nitrogen oxides in exhaust gases into harmless substances, significantly reducing environmental pollution. European countries, following the Euro 6 Emission Standards, continue to lower emission levels. According to these standards, NOx emissions from diesel vehicles must be reduced by 67% compared to older models, and AdBlue plays a key role in achieving this target.

What Happens If AdBlue Runs Out?

When the AdBlue warning light turns on, it indicates that the fluid level is low or there is a system malfunction. If AdBlue levels drop too much, it can reduce engine performance and increase emissions. If the fluid runs out completely, the vehicle may fail to start. A continuously illuminated AdBlue warning light signals that the tank is empty.

How to Refill AdBlue?

Before refilling AdBlue, ensure that the vehicle is turned off. It is also important not to confuse the fuel tank with the AdBlue tank. Avoid direct contact with the fluid, and clean any spills immediately. AdBlue can be purchased from fuel stations, or you can refill it yourself using an AdBlue pump, provided that you take the necessary precautions.

Which Vehicles Use AdBlue?

All Euro 6-compliant passenger and commercial diesel vehicles use AdBlue. Additionally, all diesel vehicles produced since 2016 with SCR technology come equipped with the AdBlue system. Vehicles that require AdBlue include cars, trucks, buses, midibuses, and agricultural machinery.

How Many Kilometers Can a Vehicle Travel After the AdBlue Warning?

When the AdBlue warning light turns on, the distance the vehicle can travel before stopping varies by model. However, in general, vehicles can still drive up to 2,000 km after the warning appears.
