AdBlue Security - Stop AdBlue Theft and Contamination

Have you ever had a contaminated AdBlue tank?


It only takes 5ml of Diesel added to 20 litres of AdBlue in the AdBlue tank to turn it into a harmful paste. A problem that is any vehicle owners worst nightmare. The first bit of advice that I can offer you is dont attempt to drive off the forecourt and call your breakdown company right away!
