Adblue far Diesel engines. advice please?

My Mercedes C250 Diesel (2016) is giving me the message "Re-fil Adblue".

Simple enough, but my question is...Is 'Adblue' just...'Adblue' ? or are there various grades and specifications. I have seen it in accessory shops but I don't want to add the wrong stuff !

Thank you.

    Adblue, or DEF ( diesel emission fluid ), is standard. There are no "grades" ( it's not like a fuel with different octane or cetane levels ).

    It's standard stuff. Of course, Mercedes will tell you to only use the 'Mercedes-Benz Genuine AdBlue' (!), but I rather doubt your car can tell the difference, only your wallet will notice...

    It is just adblue which is a urea solution used to reduce emissions.

    No grades just more expensive brands such as Mercedes own brand.
