Why AdBlue quality matters for Euro 5 / Euro 6 trucks

  • How SCR works. AdBlue is sprayed into the exhaust ahead of the SCR catalyst, where it turns NOx into nitrogen and water. Euro 5 and Euro 6 engines will not run clean — or at full power — without it.
  • Wrong strength = faults. Urea outside 31.8–33.2 % trips NOx-sensor and quality faults, warning lights and engine derate (limp mode).
  • Metals and phosphate poison the catalyst. Calcium, sodium, potassium, magnesium, iron and phosphate coat the SCR catalyst for good — it cannot be cleaned, only replaced.
  • Biuret and dirt block injectors. High biuret and insoluble matter form crystals and deposits in the dosing injector, lines and filters — costly parts and days off the road.

Handling tips: keep containers sealed and out of direct sun, use clean dedicated funnels and pumps, never reuse oil or diesel containers, and never dilute with water. AdBlue freezes at about −11 °C and thaws without harm.

AdBlue FAQ

Does your AdBlue meet ISO 22241?

A sample of AVDMM AdBlue (AUS 32) was tested by an independent ISO/IEC 17025 accredited laboratory in September 2026. The lab’s verdict: product meets specification for all properties tested — urea 32.3 % (spec 31.8–33.2 %), biuret 0.28 % (max 0.3 %), insolubles 3.2 mg/kg (max 20) and all trace metals below 0.10 mg/kg.

What is AUS 32?

AUS 32 is the ISO 22241 name for a 32.5 % solution of high-purity urea in demineralised water. AdBlue is the common name in South Africa; you may also see DEF (diesel exhaust fluid).

Which vehicles need AdBlue?

Diesel vehicles with SCR after-treatment: most Euro 5 and Euro 6 trucks and buses, many newer vans and bakkies, and newer tractors and plant. Look for the blue filler cap or check the owner’s manual.

What pack sizes do you supply?

5 L packs are in stock at the Benoni yard. 10 L, 20 L and 1000 L IBC are available on order. Tell us roughly how much you use per month and how you store it, and we will quote the right pack. Quote-only — no public prices.

Do you deliver AdBlue?

Yes. Collect from our Benoni yard, or ask for delivery across Gauteng & surrounds — ask us for your distance. Route, timing and minimum order are confirmed on the quote.

Can I top up AdBlue with water or use fertiliser urea?

No. Tap water and agricultural urea carry minerals and impurities that poison the SCR catalyst and block the dosing injector. Only use AUS 32 that meets ISO 22241, from a clean, sealed container.
