urea at about 33% concentration


theres three methods of sensing I know of, the first is an optical density tester, the second is about equivelent to a hygrometer and the third is conductivity based.


edited out the extra 33%.

4th method, smell, 5th method taste.

Mr Grylls, is that you?

I know nothing about Adblue so......is it expensive?....what is the rate of consumption 'x' per 100 kms or is it so little that 'X' per 1000kms is a more realistic measure?

I get the impression that from a user position that Adblue might be less of an overall hassle than having a DPF which requires frequent long drives at its convenience.

The max concentration of urea in human urine is about 2.3%. Not an easy thing to drink. Unless you are drinking lots of water/beer then the concentration of urea drops to almost nothing.

its moderately cheap for what it is, X per 1000 is a reasonable indication in some vehicles its set up so in theory you only have to fill it up when you service the vehicle.

like DPF its fine until something goes wrong. If you run out of adblue you get a derated engine but it re-rates once the adblue is topped up again (usually) Unlike DPF most failures dont wind up with a clogged exhaust and a mechanical limitation VS an electronic one.

~$40 for 10L and my SD4 does ~ 500k per litre. The only thing I find annoying about the process is the time it takes to fill the tank given the minuscule fill pipe to the tank. 10L take me say 15 minutes.

Consumption varies a lot, depending upon what you are doing. Gentle highway cruising uses very little, but towing something heavy and working the engine will use a lot.

I used 14 litres in 7,000 kms of "normal' driving with 1400 kms of towing 1400 kgs. Then I put 15 litres in - not sure if I filled it up - after 2,500 kms of towing around 1800 kgs.

So, 2 litres per 1000 kms for the first instance, then at least 6 litres per 1000 kms for the second. Hence my need for a way of pumping AdBlue into the tank in the bush.

My wifes Passat Alltrack has a fill point next to the fuel filler.

Fill up with Adblue from the truck points - much more sensible and far cheaper

I've noticed that too, when towing the Adblue use seems to go up exponentially. My van weighs about 2,000kg.

And I was driving very conservatively - around 95 on the bitumen and 70 on the dirt, virtually no overtaking on the really quiet roads. I reckon I need a long range AdBlue tank...
