AI Overview

AdBlue is a high-purity, non-toxic

urea solution used in modern diesel vehicles equipped with Selective Catalytic Reduction (SCR) technology. It is injected into the exhaust system to break down harmful nitrogen oxides (NOx) into nitrogen and water. AdBlue is stored in a separate tank, not mixed with diesel fuel, and is crucial for meeting Euro IV, V, and VI emission standards.

Usage & Consumption: AdBlue is consumed at a rate of roughly
to
of diesel consumption. A 10-liter container typically costs between 15USD and 53USD.
Warning System: If the AdBlue tank runs empty, the engine will lose power and may not restart after being switched off.
Safety & Quality: AdBlue is not a fuel additive and must comply with ISO 22241 or DIN 70070 standards.
Top-up Locations: It can be refilled at service stations, often near the diesel pump for trucks, or added via a dedicated filler cap (often blue) on passenger cars.
