AD BLUE Diesel Emissions Fluid for SCR Code FOUR 1/2 gallons (2010-2013)

Purchased this. Yes it’s easy to pour, but the cost is ridiculous compared to BlueDef. Both meet the same ISO22241 spec. AdBlue meets the ISO22241-1 spec. The “-1” designation relates to its transport, dispensing. Nothing to do with the quality of the material… Buy BlueDef and save some money. I reuse the containers and refill them. They are very convenient for dispensing, no drips, no spills.

Good price. Good product. I wouldn’t recommend using any other DEF, but each time I order some at least one bottle is leaking a little. There’s no cushioning in the box. So be aware when you open it, it may be messy.

I am not a tech-savvy person, so this method of refilling AdBlue is great! It is very easy. No mess. No fuss. No spills.

Bottle makes all difference in world for filling cayenne diesel vs some of the alternatives, but this comes at a cost, I think @ 4x from a big box. Many have suggested buying once, and cutting bottle end and filling with said fluid. Overall is great, works well, but I think costs too much, as well as not being terribly efficient- I used four bottles which though recycled seems wasteful. I can’t help but think these are the Audi equivalent of illy espresso pods

Cost to much fit fine

I have no idea what it is or does other than I need it in my BMW. I accidentally spilled some and it crusted over like dried salt on the waters edge of the Dead Sea.The instructions on how to fill it were clear enough - I put two bottles in and Bobs your uncle

This bottle fits the tank on the Jaguar XE Diesel perfectly and is drip free. I purchased the 4 ea 1/2 gallon bottles for supplementing fills between service intervals. I will use these same bottles over the life of the car, having them refilled at/from a bulk and more reasonably priced source (These were reasonably priced compared to the retail market, but the bulk price of Ad BLUE is considerably less).Would I purchase again? Yes, but only if I needed to replace my existing containers/empty bottles.

Easy to use and worked great in my VW golf.
