They have found a leak on the sprayer system, but even so I find it had to believe the amount lost in 4500 miles basically 30 litres plus.

Also had the permanent warning low ab-blue countdown from 200 miles come on, which is reassuring I suppose something works

My warning came on after 3500 miles, took 9 liters to fill so if it holds 17ltrs? ir still had 8 ltr's in it.Does this sound correct?
I bought 10 ltrs from morrisons garage for £11.

I suppose it does, 8 litres would get you around another 3000+ miles. A lot better than I've had, but still waiting for parts to come in to fix my ad-blue issue !!!

This morning I was clay shooting with a petro chemist specialising in auto fuels, the talk got around to Ad-Blue.
As you know the active ingredient is urea, he told me that to be effective in a diesel engine neat urea needs to be injected at a rate of 7 grams per litre of fuel.
As commercially available, 'ready to use', Ad-Blue is pre-diluted at a 20% rate, to be effective Ad-Blue needs to be injected at a rate of 35 grams per litre of fuel.
Or 1 litre of Ad-Blue for every 28 litres of diesel.
No wonder you are using so much!

Very first upgraded D22 - 10 years and 72K miles and still going strong!

6800 miles in now and 55l of adblue, at this rate i am going to buy an IBC, mount it in the bed and just have a pipe down on drip feed!!

Most of our new forestry harvesting machines use adblue, while I was filling up my truck in the wood today the forwarder driver said that when he is carrying timber uphill (machine working harder) there is a considerable difference in the amount he uses without the same correlation in l/hour for diesel.

I will never be accused of having a soft right foot, but i dont tow anything and Welsh country roads are not exactly race tracks. I still get 34ish mpg so I cant be driving it that hard?

Think you need to buy shares in the stuff too. 123 miles to a Litre or 2000ish Miles to a tank of the stuff I would guess you have an issue somewhere.

That seems a long way from what Nissan are quoting, someone else on this topic took theirs back to nissan and found a leak on the adblu system.

My NP300 was delivered with 500 miles on the clock, a couple weeks after delivery I received the AdBlue warning light so purchased 10l and filled it up. I'm just shy of 2400 miles on the clock and its on again!
My mate has a Mercedes and the computer display allows you to select AdBlue which shows amount in tank and expected mileage, he had 17000 miles to go before he needed to top up.
My NP300 is just road driven around 50-60mph, no hard acceleration etc
This is extremely poor consumption. Has anyone had luck with a dealer adjusting or fixing consumption?

On the subject of AdBlue I think I just found the most expensive stuff ever!
Just walked into a garage who's charging £25 for 4 litres!!!
