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!
