I found this graph in a presentation online. It is the amount of cetane increase from using 2-ethylhexyl nitrate (2EHN), the most common cetane improving additive. Ethyl (now Afton) is the biggest supplier of this additive in raw form. Aftermarket companies typically buy this additive and mix it into their own "cocktail". Most often at about 30% of the total. (Straight 2EHN is dangerous to handle and not likely available on the shelf).

Compare this graph to the additive's treatrate and see what you get.

didn't they try to use that as a lead substitute in gasoline but it proved to be more poluting than lead?

Posting to see , I know that most additives are just the same few chemicals , but vary mostly in the amounts of each .
