In a typical chemical reaction, the air-fuel ratio must be a minimum of 14:1 (see Stoichiometry).
In addition, changing fuel maps to coincide with the stoichiometric ratio for gasoline combustion may also realize performance increase.
In general, the alkaline-earth metals form silicides with the following stoichiometries: MII2Si, MIISi, and MIISi2.
The term stoichiometry was first used by Jeremias Benjamin Richter in 1792 when the first volume of Richter's Stoichiometry or the Art of Measuring the Chemical Elements was published.

In patristic Greek, the word Stoichiometria was used by Nicephorus to refer to the number of line counts of the canonical New Testament and some of the Apocrypha.
