How the SCR system works in your BS VI truck
5 stages from engine to clean exhaust
Engine
Burns diesel, produces harmful NOx gas
DOC
Oxidation catalyst pre-treats exhaust
AdBlue Injected
32.5% urea sprayed into hot exhaust
SCR Catalyst
Ammonia reacts with NOx — neutralises it
Clean Exhaust
90%+ NOx removed — only N₂ + H₂O
What goes wrong with cheap AdBlue: Wrong urea concentration (below 32.5%) means ammonia is insufficient to neutralise NOx. Over time, incorrect urea deposits biuret crystals inside the injector nozzle and SCR catalyst. Once blocked, the catalyst cannot be cleaned — full replacement costs ₹1.5–4 lakh.
Why CareBlue protects your SCR: CareBlue is manufactured at exactly 32.5% urea concentration, verified by NABL lab testing on every batch. Zero biuret contamination. Zero metal ions. ISO 22241 certified — same standard as Tata and Gulf, at 20–30% lower price.

How to read a refractometer: Place 2–3 drops of AdBlue on the glass prism. Hold to light and look through the eyepiece. The line where blue meets white = urea %. ISO 22241 requires 32.5% ± 0.8%. Below 31.8% = diluted (FAIL). Above 33.2% = over-concentrated (FAIL). CareBlue hits 32.5% every single batch.
