Diesel Exhaust Fluid

Castrol AdBlue is a high quality aqueous urea solution conforming to ISO 22241 specifications and made under license from VDA (German Association of the Automotive Industry). It is used as a consumable in vehicles fitted with selective catalytic reduction (SCR) after-treatment device, in order to lower NOx concentration in the exhaust emissions from diesel engines.

Castrol AdBlue is essential for the correct operation of SCR after-treatment device used in diesel engines, to meet BS IV and BS VI norms.
