Air/Fuel Mixture

This is what is sounds like it'd be--the mix of gasoline and air that allows your engine to produced power. There is an ideal ratio of air to fuel that is most conducive to a complete burn of the gasoline, which is 14.6 parts air to 1 part air, also known as the "stoichiometric ratio." (I challenge you to work that into a sentence sometime int he next 6 days without the person you're talking to noticing.)
