“The Greenchem Adblue 10Ltr came with a flexible screw in connector recessed into the plastic container. This is a very useful addition as it enabled me to refill the 4Ltr starter kit container I purchased at the same time. I chose not to use the starter kit connector after reading reviews on the internet. So I decided to put Adblue into the car tank using the 4Ltr bottle with the flexi hose connected and it worked flawlessly. I then screwed the flexi connector to the 10Ltr bottle and refilled the 4Ltr container ( it's much easier to handle when filling the tank).. I was happy after putting 8Ltr in. Because I was mindful of warnings not to overfill the tank. The inclusion of the flexi hose made the job straightforward and helped prevent any mess from spillage.”
