Wynn's Crystal Clean & Protect AdBlue for SCR Diesel Systems - 500 ml

Does what it says on the label ... or rather I assume it does because there's no way of knowing for sure -- buy when it comes to AdBlue it's definitely not worth the risk of not using an anti-crystal additive. Only downside is the limited shelf life even when unopened and even shorter when opened.

Funciona bien y este formato es más económico me gusta

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.

Fehler alle weg. Keine Kristalle mehr zu sehen.

ottimo prodotto
