🔍 WHAT IS MEANT BY “MACHINE UREA”?
Automotive urea is commonly known as AdBlue® :
🧪 a mixture composed of 32.5% technical urea and 67.5% demineralized water .
It is not an engine additive, but a chemical agent that is used in diesel vehicles equipped with an SCR (Selective Catalytic Reduction) system .
📌 It is non-toxic , non-flammable and biodegradable .
♻️ WHAT IS UREA USED FOR IN DIESEL CARS?
The real goal of urea is to reduce polluting emissions 🚫🌫️.
Here's what happens:
-
AdBlue is sprayed into the hot exhaust gases. 🔥
-
It transforms into ammonia (NH₃) .
-
Ammonia reacts with nitrogen oxides (NOx) .
-
The result? Nitrogen (N₂) and water vapor (H₂O) – both harmless to the environment! 🌱
➡️ This process is essential to comply with Euro 6 and higher environmental standards.
📍 WHERE DO YOU PUT UREA IN THE MACHINE?
AdBlue doesn't go in the diesel tank! ⛽
It has a dedicated tank , which can be located:
-
next to the diesel cap 🟦
-
in the trunk 🚙
-
under the hood 🔧
👉 The tank usually has a capacity of between 10 and 20 litres , and can be easily refilled even independently .
⚠️ WHAT HAPPENS IF YOU RUN OUT OF UREA?
If the urea runs out completely:
🔺 A warning message appears on the dashboard .
⛔ If ignored, the car will not restart after switching off !
⚙️ It is a protection system required by law.
💡 Tip : Top up the fluid as soon as the warning appears or have it checked during every service.

Car: 1 – 1.5 litres every 1,000 km
-
Vans/Trucks: up to 5 litres per 1,000 km
💸 A 10-liter canister costs between €10 and €15 . It's a small investment with a reduced environmental impact.
