Basically lowers the amount of toxic particles from diesel exhaust gasses. Don't think petrol is 100% safe cause petrol engines produce a fair amount of carbon monoxide which is also toxic.

Find a petrol station that has adblue pumps (they will be by the HGV pumps) as it is FAR cheaper (69.9p per litre IIRC in Kent)
Oh! This is my first diesel car that's required adblue - I was fascinated as the dealer talked me through it. That's a really good steer for getting cheaper adblue. Thanks!

The Adblue tank holds 12 litres ( the dealer told me it was 3 litres ). I've done 1200 miles and the trip computer is giving a range of 5000, so 6000 sounds about right assuming the tank was full on delivery.

One word of warning if you have not used Adblue before, it's very corrosive so needs to be washed off paintwork as soon as possible. Also it's not blue it's clear, I know coach drivers who have kept some in an unmarked container, then another driver has topped up the cooling system with it resulting in a new engine. It's a good idea to keep a spare litre in the boot (in a bag with gloves and funnel) as if it runs out I think the car will go into 'limp home' mode, this is what happens with Hgv's.

You will get a 1,500 mile warning when you get low, so nobody should ever get caught out and run out.

Also if you do run out completely then the engine will refuse to start.

Isn't AdBlue just wee? Can't you just stick your own nozzle in the tank and fill up if you run out?

It is ‘basically’ pigs urine... however it is completely synthetic and not a natural product.

You also need to be careful which adblue you put in. We have a jag xe at work and someone put some cheap garage stuff in and the car didn't like it. Apparently there are subtle differences between brands and some manufacturers systems check

There are basically two methods used to manufacture AdBlue. The ‘Hot-Melt’ Virgin Urea production method is widely accepted across the industry as producing the highest purity grade of AdBlue. This is because it eliminates the risk of contamination during manufacture. The urea is in its ‘virgin’ liquid state when it is combined with the de-ionised water so there is no chance of contaminants being introduced during manufacture.

NEVER use AdBlue that is manufactured by dissolving solid urea. This method of manufacture is by the dissolution of solid urea in de-ionised water. Although this method may meet the ISO and DIN standards set by the VDA there is a strong chance that the solid urea could have contaminants present from the manufacturing process and also from bulk storage and handling in typical open warehouse environments.
