Next time maybe you should just not post misinformed drivel. Simply put, I don't think you know what you're talking about with regards to gas additives. It's not flaming, it's calling you out when you post misinformed or untrue statements.
gas additives largely function to change the combustion temperatures within the cylinder. There are many changes to both the volumetric efficiency, the exhaust temperatures and the composition of non-combusted exhaust "gases" as a result of changing the combustion temperatures. In many electronically controlled engines, the ECU will "see" these changes and use different fuel maps, which may lean out the engine (less gasoline injected into the cylinder), slightly increasing MPG, and changing the composition of the combusted "gases". Increasing the volumetric efficiency of the engine will, in fact, raise the MPG, too (more work done with the same amount of fuel), tho the amount is largely dependent on an engine's current state of tune (number of hours, maintenance cycle, etc). Many gas additives also contain chemicals which act as detergents (simple bases) which can remove/break down jellied gasoline or other gunk within the fuel delivery system, and on fuel injected vehicles, clean the injectors to some extent. All these things are beneficial to increasing the efficiency of the engine, and could quite feasibly increase the MPG, and/or change the composition of the exhaust.
