How many miles does 10l of adblue cover out of interest?
My van only holds about 10 litres in the tank (I can’t quite get the full 10 litres in when it asked for a refill) and is asking for its third refill at just under 10k from new (big van averaging about 30mpg) so over 3500 – 4000 miles from a 10 lite bottle. I’d imagine smaller vehicles would get more and it sounds like some have big enough tanks that its covered by service intervals so I guess some drivers dont really know what they’re using.
A lot wil vary of driving style – its not using adblu all the time, only when a regen of the DPF is required – so driving patterns will vary between drivers and the size / nature of the filter and how often it needs to be cleaned will vary from vehicle to vehicle.
If the shortage happens, those engines will probably need to be remapped to allow them to run on less or no Adblue.
Not using it is not an option – you can’t just tell the ECU the DPF isnt there – you have to have the filter system that the adblu cleans removed otherwise it clog up and you might as well have just stuffed a potato up the exhaust.
