About AdBlue


Many customers with diesel cars ask us “What is AdBlue and why do I need it?”. Here we try to explain…

AdBlue is a key ingredient in certain diesel models system that helps reduce nitrogen oxide emissions – and, just like the oil in your engine, it must be kept at the right level. If you need it, you’ll have an AdBlue filler cap under your diesel filler flap (or in the boot on older models). Your vehicle will warn you when you’re within 1,500 miles of needing to top up your AdBlue, and it’s vital that this is done to ensure your engine keeps working as normal.
