RedexAdBlue Additive 5L, AdBlue With Easy-Pour Spout, Reduces NOX Emissions, Quick & Easy Filling, Keep Spare In Boot, Premium Quality AdBlue Diesel Exhaust Fluid, No-Spill Bottle, 5 Litres

Odd situation to star rate as the product it self is 5 star, but my experience using it was 3 star.Pros : It states ISO22241-1 on the container, this is what Audi recommends. There are others ISO 22241-2 & -3 I don't know the difference but don't want to chance it, as can't find a definitive answer. Can order various measures, many others 10L only. Perfect lifting support handle when filling. The cap/top is a good fit, so won't leak on delivery unless the bottle is punctured. The 'tiny' filling tube was a really good snap on fit and didn't leak. Spout is positioned right on the flat side of the bottle, so you get all off the mixture out.Cons : Was a right mission getting the child safety cap/top off, had to get a G Clamp to squeeze sides then push down and used the clamp to help turn. Thread on cap did not match my Audi filling accessory, so no standard sizing. The nozzle that came with the bottle was good and didn't leak but far to short for my car, so had to use it by putting that through another funnel where It became a two person job to avoid spills and splashes. This was my experience simply because I couldn't use my own attachment. The use by date 'code' was a bit confusing so had to phone customer support, who were very helpful.The warning light message on the dash did disappear, and have driven the car for two days and all appears to be good, hopefully that stays that way. Don't think my Cons would deter me from ordering again, now I am aware of what to do AND no warning message displays. Was easy long term as 5l is lighter to hold, plus the handle, as its not a quick job all containers will have air locks, plus if you take care to avoid a mess.That's my review, a bit long over just AdBlue but hope this helps, as was fed up just reading about leaks only.

Good product and cheaper than my local garage

Good product, simplicity it's self to use

Easy to use and spout prevents spillage on car.

The only draw back for this Adblue vs the competition is the spout supplied is tiny and depending on your vehicle it makes it hard to fill up without spillage.Other than that I can't fault this.

Great product prevented any ad blue build up.

The spout attachment could be longer. Difficult not to make a mess.
