You are correct, of course. My "older" cars got better mileage than my newer cars DID ( they have since been MODified). The point I was attempting to make was ... it shouldn't take more gas to "clean up" the combustion of gasoline.
Efficiency is the name of this combustion game. If 100% efficiency is achieved, we still are left with a CO2 by-product of this combustion process...as well as the heat of combustion forming NOx ( similar to lightning forming NOx). CO is an indicator / measure of incomplete combustion, as is unburned HC.
This CO2 is a tough nut to crack. I am proposing C & O2, even though connected by a double bond, are both "re-combustable". C is carbon ( coal is C) and O2 supports combustion. It's the double bond which creates a "difficulty".
