That's not a claim I ever recall seeing for AdBlue

I have seen 70-80% NOx reduction quoted, which sounds plausible.

On some vehicles, some of the time, maybe. That's not the same as proof of general

Maybe, just maybe - for example, there is an "emissions charging zone" in London, and a product that reduced emissions might allow a truck to come below the emissions threshold and so avoid paying the charge. But it would need extra safeguards, for example a warning light / power reduction if insufficient product had been added to the tank (and so the emissions were higher). And, of course, you would need to demonstrate that your product actually reduces emissions on that specific type of vehicle rather than relying on test data for a totally different vehicle.

How is this really?
Methane is formed during the combustion process as the larger molecules get broken down.
