Redex Adblue® is for use in diesel cars to reduce emissions by up to 80%. Running out of Adblue® will cause your car to stop, so having a spare bottle to hand is sensible and will help to keep your car running for longer. Topping up can be difficult, as you need the right kind of bottle. Redex Adblue’s® unique bottle has a secure opening and locking system so you don’t need to freely pour it, preventing nasty spillages and odours. The bottle can be stored safely in your boot without risk of leaking so you can use it any time you start to run low.

Features:

  • Easy pour spout
  • 5L bottle
  • Reduces NOX emissions by up to 80%

    The price in-store is £8.38 normally and not £11.59. The discount here is £1 plus VAT - £1.20.
    The OP is comparing the online delivered price with the discounted store price.

    I've got an Audi. When it gets low I get a warning that the car will refuse to start after x miles, and at one point I had to get the system checked because it came up with "adblue system contamination" or words to that effect.

    This guy also tested it on what appears to be a VW van

    Apparently adblue goes off if stored for long. Don't buy loads to stock up. (edited)
