Try not to bring a knife to a gunfight.
Oh my, you seem like a person who is capable of doing research. Yet you don't or can't understand that Adblue (tm) is not used to make diesel. It is made separately and goes into a separate tank. At no point does it even get mixed with diesel and does not get burnt in the engine. Instead it is sprayed in very small quantities into the exhaust, often into the catalytic converter and converts nitrogen oxides into other less toxic gases. DYOR.
This additive, has nothing to do with Greenhouse Gas abatement. The purpose of it is to reduce the release of NOx for the benefit of people who live or work near busy roads and highways.
Perhaps y'all would be better off using its correct [non-trademarked] name DEF, Diesel Exhaust Fluid, which is pretty self explanatory.
But why does this topic keep coming up here? LCK don't make any.
