How long does stored fuel last?

How long will gasoline last with stabilizer?
Fuel system stabilizer is not a cure-all and it doesn’t last forever. It must be mixed with fresh gas before the vehicle is stored, not added to already old gas. It can slow down the oxidation process and keep gas fresh for as long as 12 to 15 months.
