Simple gasoline engine air/fuel stoichiometry says you need 14.7 lbs of air to 1 lb. of fuel. If you add more air, then you need to add more fuel or you will generate a lean condition which will raise exhaust gas temperatures and eventually cause engine damage. If you add more fuel than necessary, then you generate a rich condition which wastes fuel and reduces mileage. Engineers/chemists know this. I guess the rules of mathematics and chemistry don't apply to everyone else.

Agree, this is just the basic equation. BUT (large BUT)there are several significant variables that balance EMISSIONS, ENGINE LONGEVITY, POWER AND ECONOMY.
Engine timing, and on today's engines valve timing as well as EGR can all be juggled to accentuate one over the other(s).
