AdBlue

 I top my AdBlue up after every trip.

The easiest way I have found is by using an empty water bottle with the pull up type lid.

Fill this from the AdBlue 5l bottle with a funnel, and then you can top your tank up without spillages as you squeeze the AdBlue into the tank.

I keep the bottle in my Gas Locker........just in case!

I find that using the spout that comes with the Adblue is easiest. It's a press fit into the top of the container & a push fit into the filler neck.of my car ....  but I've only ever filled my car with Adblue & not seen the filling arrangements of other vehicles.

My motorhome has now done just over 4600 miles and I was wondering whether to take the bull by the horns and top up the AdBlue before I get the warning light? Does anyone know whether AdBlue goes off? I did purchase a container when I got the van in 2019 and I am just wondering whether I should buy a new bottle, its hardly a kings ransom!

Not 100% certain but i think AdBlue has a shelf life of 18-24 months.

Isn't the tank meant to be drained every 2 years? No real idea but read that on a post

Yes, it does 'go off'. An internet search revealed that it has a shelf life of 12-24 months depending on temperature. Only this morning I dumped some that was just over 12 months old.

The first warning light gives you several hundred miles notice before you’re in deep trouble so there’s no immediate rush.

Some AdBlue containers don’t have a long enough spout to open the flap inside the filler of the van and then you need to improvise with something like a funnel.

Our 2018 Peugeot based motorhome does around 6000 miles per tank of add blue
