AdBlue
I'm looking for advice please. Bought a new motorhome last year and full of enthusiasm I bought some AdBlue. Not had a diesel engine requiring this before. Health and Covid-19 got in the way of using the motorhome much, so I have a quantity of Adblue that has what I take to be a 'Use by date' of 18.10/19 on the container.
Can anyone confirm whether this stuff has a limited shelf life, and if so, how to 'safely' dispose of any left over please? If it does have a time frame for use, I question how effective the stuff already in the vehicle tank will now be, as it will have been in there well over a year now!
Thanks in advance,
John E

Add Blue has a shelf life of up to 12months (may have a use by date on container)
it is not classed as a hazardous material ?
Must only be disposed of via local /national instructions
Not into drains watercourses or the ground
Check with your local council enviroment office

Taken off google
Provided that it is kept in the optimal conditions — out of direct sunlight and at a temperature between -6°C and 25°C — your AdBlue can last up to 18 months in storage. If you store it at a higher temperature than this or in a vented container, the shelf-life will only be around 6 months.15 Aug 2019

You make a good point about the AdBlue in the tank. I dont know what size tank my car has but i drove 15,000 miles in 12 months before it needed refilling.

Interesting thread for me as I did exactly as the OP did. When I got the van I purchased some AdBlue so will have to check the sell by date!!! Useful reminder.

Could I share my experience. I bought a 10 litre bottle of Adblue and when it came to refilling found that pipe was not long enough to open the gate in the neck of the filler tube, so bought a 3.5 litre bottle, used that, decanting from the 10 litre bottle.
Then discovered that BP garages have an Adblue pump. The pipe is long enough and fits snugly with no spillage. Adblue is pumped In and the pump stops when full and it’s cheaper at the pump. For me now, no worries about sell by dates, spilling or not getting the pipe to open the gate.
The dash warning light gives plenty of notice when adblue is running low, another 1500 miles before limp mode. That works for me.

Thank you one and all for your replies.
I will certainly look at garage forecourts with a view to topping up there when the time comes. It sounds as though I have a long way to go before it will need topping up.
Good feedback. Thanks.

It is a mixture of water and urea. It would not be significantly degraded in storage in solution as it is stable. It is about as stable as salty water so I really would not worry about it being 12 months old. Just give it a shake and tip it in.

If your car has 26k on the clock it's fair to say that some has been added at service. I've done about 15k in my ML but have added a gallon or 3 on an had hoc basis .... the car has never actually asked for any though. I believe it's possible to get a level check on later cars .... but not mine. 🤔
