During storage, some classes of hydrocarbons in gasoline blends, particularly olefins and diolefins, are able to slowly react, at ambient temperatures, with the oxygen in the air. The formed oxidation products are responsible for the formation of an insoluble solid, commonly called deposits or gums.

Gum formation is because of oxidation of olefins which form a insoluble solid called gum. Thus, Gum formation is because of the oxidation and polymerization of olefins (unsaturates).
