Wynn's Anti Cristallisant for Adblue® Vehicles Commercial, Additive Adblue® Anti Crystallization 500ml

Worked as claimed so definitely worth the cash and the 5* rating given.

Appears to work a treat.. well worth putting in to prevent crystallisation of the Adblue system

Excellent works well. Good quality

Anti crystallisation additive, for the ad blu additive ? Saves expensive adblu tank/ pump replacement.

Used this in my Skoda Superb 2.0 tdi for the last 100k miles. Had no issues with adblue system whatever.

Great product thanks

I've been using this product for around 2yrs now and it has stopped the forming of crystals around the adblue filler and any splashback from filling, so I can only assume it has done it's work inside the adblue tank as well. I normally add 100ml per 10 liters of adblue (outside, before filling, give it a shake and fill up your tank) I've heard some horror stories about adblue tanks and systems blocking up due to crystallization and the costs involved in the repair and replacement of components etc so I am hoping this product will do as it says on the bottle and the signs are it does. I only use around 60ltrs or adblue a year so to keep my vehicles system clean is a priority... tbh, I don't know why they can't add it at manufacture, although I guess it's another add on you need to buy to do someone else's job. So far very pleased with product and no noticeable detrimental signs, apart from a slightly different smell at the tail pipe.

This is to delay any worries about Adblue in a motorhomes tank through being left over winter and not moving. This avoids having to spend on removal and replacement of tank, injector and flushing out of system. Some have found this very expensive through not using Wynn's.
