I have a 10 litre container of Adblue with maybe a couple of litres in the bottom. The  Adblue reminder hasn't come up yet but is there any reason I shouldn't top up early. Reason is we are having building work done and need to clear the garage and getting everything into the spare bedroom is a challenge. Getting rid of the big plastic container would help.

 

TIA

No reason not to top up if there is space to take the AdBlue.  You obviously do not want to overfill / overflow.

 

What does the car show as range for your AdBlue and what capacity it has or can be added?

 

eg.

Adblue range is shown as 3000 miles but no capacity shown on my display. I can only recall this showing when the low level warning appeared. I'm just not sure if any problems could be caused by overfilling since I will have no guide to capacity. 

It's no big deal and for the quantity involved I'll probably dump it. Was just interested to see if it could be used rather than wasted.

Thanks

It will easily take 2lt if you only have 3000 miles left.

I would have thought so. Maybe I'll put a couple of litres in and get rid of any left after that

I've topped mine up without any problems before now before the warning has come up. Can't see why it should cause any problems.

 

As for overfilling, this is avoided if you use a filler tube with a valve in it. I think the only consequence of overfilling is that you will spill some in the boot area which you don't really want to do. 

I understand if overfilled the float for the level sensor can get stuck up and cause issues. Hence you must use the filling tube with a flow cut off and not overfill. These normally come with the adblu container.

The 10+ litre bottles of Adblue I've bought from the garage have never come with a "cut off" tube, just a normal filler tube.

Interesting about the float. This is the type of thing that concerned me in the first place.

This is only the second 10 litre bottle that I've bought and both have had simple flexible spouts - no valve.

 

In the end there was more in the container than I thought even after putting a couple of litres in so I've made space to keep it. Getting 35 years worth of garage junk into a small spare bedroom has certainly been an exercise in space management

Are you sure? The filler tube on the ones I get from Sainsbury or Halfords have an air return pipe in the nozzle, not a valve as such. You just stick the filler tube fully into the tank and when the liquid level reaches the end of the filler tube, air can no longer get back to the container and flow stops.

You get all sorts, but sometimes the issue using the ones with 10 litre containers is stopping putting more AdBlue in then lifting out the nozzle of fillers in cars and not spilling.

As it is Filling Station pumps are just the same, fill with care and do not spill.

Just keep the old empty container and half fill from a new one when you next need to top up. No spillage in the car if you then use the half full one and don’t try and fill the Adblu tank completely. I just put 5lt in. You are then left with a half full one for next time.

I find the spill happens trying to get the hose to the tank with the container full.

That is the 'Simply Clever' way to do it.

Which comes back to the point of the OP.   A couple of litre top up is OK if there is room for it and done carefully.

Think I see what you mean now. There's a small pipe running along the side of the main spout, open at each end. Had never noticed it before and wouldn't have realised what it was for if I had. Every day is a school day!

Yes the little pipe stops the tank being overfilled, but then try getting the pipe out of the tank and the bottle upright without spilling any.
Good luck!
