Febi Bilstein AdBlue 171331 - Premium Diesel Exhaust Fluid for Cleaner Emissions

Keep your diesel engine running clean and compliant with Febi Bilstein AdBlue 171331, a premium 3.5-liter solution meeting ISO 22241 and DIN 70070 standards. This crystal-clear fluid injects into the exhaust to break down harmful nitrogen oxides into harmless nitrogen and water vapor, helping trucks and vans pass emissions tests effortlessly.

Purpose and Specifications

AdBlue powers Selective Catalytic Reduction (SCR) systems in modern diesels, slashing emissions by up to 90% without hurting fuel economy or power. The 3.5-liter bottle weighs just 3.865 kg, perfect for topping up during routine service. Store it between -11°C and 30°C to maintain peak performance - it freezes below -11°C but thaws safely in your vehicle's system. Shelf life lasts 12-18 months in a cool, shaded spot away from sunlight, extending to 3 years under 10°C.

When to Use / Replace?

• Low warning light or dashboard alert: Refill when the system signals empty, typically every 10,000-20,000 km depending on your diesel's load.
• Before emissions tests: Top up every 6-12 months to avoid limp mode or failed MOT checks.
• Failed SCR check: Replace if fluid smells off or looks cloudy after 12 months from fill date.

Practical tip: Use within 12 months of opening for best results, and always pour slowly to prevent spills.
