Petroleum-based gasoline without any ethanol will still succumb to oxidation and volatile compound evaporation in a sealed container or tank, but these processes usually occur more slowly in pure gasoline, so you can usually expect it to last at least six months when properly stored.
Because pure gas is hydrophobic a. Fuel stabilizers available on Amazon from brands like STA-BIL are petroleum-based additives you can mix in with gasoline prior to storing it to slow oxidation and volatile compound evaporation and extend the shelf life of the gas.
Depending on the product, the stabilizer can increase gasoline shelf life to between one and three years.
