How good or bad 6k miles is depends on how many litres your tank holds - for example the latest model Audi A4 could be either 17 or 24 litre and also was it full on delivery.
We hired a campervan in Australia which had adblue, we did not need to top it up in 5000kms.
The trucks and coaches have big tanks for it but they buy in big drums.

Hi folks I am back I started this topic and thought I would just bring you upto date on what I have found on the net. it seems that if you totally ignore the advice to add blue when your vehicle runs out of blue your vehicle will not start.???????
I believe this is so you cannot put pollutants in the air and there are petrol engines also fitted with add blue.
as the blue is injected into the exhaust system after the engine exhaust manifold it is suppose to clean the internal parts and the expansion box/ silencers etc perhaps we will get longer life out of our exhaust systems. To be honest the last time I remember fitting a new exhaust system to any car I owned was a petrol Ford Serria some time back in the eighties which burnt from the inside out. The Diesel version 2.3L was a 1.9L opened up Pug engine. I have never had a petrol engine since as I always found the diesels to be better tow cars.
I think you will find Adblue is there to change the environmentally damaging nitrous oxides back to harmless nitrogen.
Diesels in part due to their higher efficiency than petrol engines burn more of the air's nitrogen into various nitrogen oxides hence the need to address this. With improved petrol efficiency one will expect just the same outcome, creation of more nitrous oxides and a need to cure it.
Nitrogen can make you seriously light headed in a confined space.
Guinness use nitrogen to give that lovely white/creamy head on your pint.
Maybe that's why I get P#SHED quicker on the present day product.
