What is Adblue

Selective catalytic reduction (SCR) is considered the latest technology for cleaning the exhaust gases of diesel vehicles. A liquid is used to treat the exhaust gases and remove the pollutant nitrogen oxides (NOx).

The liquid used in most cars is called AdBlue and is a registered trademark of the German Association of the Automotive Industry (VDA), which ensures compliance with the standards. This liquid is stored in a tank in the car, but unlike gasoline or diesel, it is not injected into the engine, but is directed into part of the car’s exhaust pipe. A chemical reaction converts the harmful NOx emissions into harmless nitrogen and water.

What materials makes up AdBlue?

Some people believe that AdBlue is made from pig urine and has a blue color, but neither is true; AdBlue is a colorless liquid made from high-purity urea and deionized water.

What autos utilise AdBlue?

Modern technologies such as SCR and AdBlue are still mainly used in larger and more expensive diesel vehicles. The reason is that the systems are too large and too expensive to be installed on smaller runabouts.

Tests have shown that small diesel vehicles without SCR, such as the 2016 Volkswagen Polo 1.4TDI, are as toxic as a fully loaded SUV. Measurements by the Institute of Transport Research at the University of Leeds found that the Polo emits 1.2 grams of nitrogen dioxide per kilometer driven, the same as a fully loaded diesel truck with a 13-liter engine.

Does my car use AdBlue?

When buying a new or used diesel vehicle from a dealer, the seller should explain what features the vehicle has, especially if it runs on AdBlue. Some vehicles have a blue or black screw cap for AdBlue next to the filler cap on black diesel vehicles. On some vehicles, the cap is also located in the trunk or engine compartment. Refer to your vehicle’s manual for information on your vehicle’s system requirements.

How much AdBlue do I need, and how long does it last?

The size of the AdBlue tanks depends on the make and model. As a guideline, the Volkswagen Tiguan SUV has a 12-liter tank and the Passat station wagon has a 13-liter AdBlue tank.

Fuel economy depends on vehicle size and driving style, with more fuel-efficient cars and drivers consuming more slowly; VW estimates that the Tiguan and Passat use 1.5 liters of AdBlue per 620 miles driven, with a full AdBlue tank. suggests that the Tiguan can travel between 3,000 and 4,000 miles and the Passat between 4,000 and 6,500 miles.

Can drivers refill AdBlue themselves?

Automotive workshops are required to top up AdBlue as part of regular diesel vehicle maintenance. However, it is also possible to refill AdBlue yourself. The words in your snare

Is all AdBlue the same?

Most AdBlue mixtures consist of the same amount of urea (32.5%) and deionized water (67.5%), but there are also BlueTech, Bluedef, or simply “urea water,” which is another name. Those without the AdBlue brand may not be of the same quality and could damage your vehicle’s engine.

What happens if the AdBlue in your automobile runs out?

If the AdBlue level in the vehicle starts to drop, a warning is issued before the engine is started, usually indicating how many kilometers can still be driven. If the AdBlue level is too low, the engine cannot be started until the system has been refilled.

If the AdBlue runs out while the vehicle is running, the power and performance of the engine will be reduced. This is to avoid possible damage to the system. In this case, it is recommended to immediately go to the nearest service station where AdBlue is available and refill the tank.

Can I substitute water for AdBlue?

Although AdBlue is mainly deionized water, do not use water to fill the tank, as all AdBlue brands meet certain standards and the use of non-recommended products could damage the vehicle’s SCR system and require costly repairs that are not covered by the warranty. They also do not help remove harmful exhaust gases, let alone water.

What should I do if my AdBlue warning light illuminates?

Vehicles using AdBlue will provide adequate warning before the AdBlue supply runs low. After the AdBlue warning light illuminates, the AdBlue supply may run low in approximately 1,200 to 1,500 miles. The AdBlue warning light will remain on until AdBlue is refilled. If your vehicle is due for service in the next 1,000 miles, you should wait until your mechanic or dealer refills the AdBlue. If not, you should do it yourself as soon as possible.
