Welcome to the Out&AboutLive forums, Garry.

I don't know what "B I U" means (and I have deleted your two other duplicate postings).

I'm guessing from your posting's title that you have accidentally put AdBlue in your motorhome's diesel fuel-tank and are seeking advice on what to do about this.

A GOOGLE-search on adblue in diesel tank will produce plenty of online discussion about this. This is just one example

and I've copied the advice below

I've put AdBlue in my diesel tank by mistake will it do any damage?

Yes it will, Do not turn the ignition on !!

AdBlue is really nasty stuff. It is not a fuel or fuel additive. It is a mixture of manufactured urea and ionised water. It will corrode metals and damage plastics used in the fuel system and engine. AdBlue is used to spray minute amounts into the exhaust system to reduce emissions and is totally separate to the fuel system. The AdBlue system is made with safe materials that are not damaged by it. Unlike petrol and diesel which have similar specific gravities and readily mix with each other, AdBlue is much heavier and sinks to the bottom of the fuel tank. The bottom of the tank is where fuel is drawn from to feed the engine. Turning on the ignition, even before starting, activates the fuel pump which circulates diesel through the fuel system. In this case it starts circulating AdBlue through pumps, fuel filter, common rail and back to the fuel tank. If you hadn’t realised that the diesel was contaminated and started the engine it will eventually draw neat AdBlue into the injectors and cylinders and although it may run initially it will soon stop as the AdBlue does not combust. It will now be reacting with all the components it is in contact with.

What is a safe amount of AdBlue?

Absolutely NONE !Even the smallest amount such as half a litre could bring your engine to a stop. Do not delayIt is essential the problem is dealt with promptly to minimise any damage. At worst the vehicle could be a write off due to the cost of parts and labour to replace the whole fuel system and the engine. At best the fuel filter will need changing after the contaminated fuel has been purged and replaced

If you have accidently put AdBlue in your diesel tank , Have it drained straight away and cleaned , if you have not driven or started it . It's a different issue if you have

Not really Steve928 

It may be a stark warning to others not to let this happen to them, as it can happen so easily . Thankfully some are lucky and it does not always cause horrific damage to the fuel system especially if noticed quickly and maybe not started or driven. A lot of work sometimes in rectifying and cleaning of same from the fuel system and so many owners do not realize this.  

I hope Garry got away with it , it would be nice to know if he did 

Should the manufactures have more warning stickers (NOT TO ADD AdBlue to the Diesel fuel) and maybe re think and have the AdBlue filler in a different position from the Diesel filler , as it used to be in a lot of vehicles when AdBlue was first introduced  into the market
