I hate the new spill proof containers. No vent cap and delivery is
blurp, blurp, blurp. You have to force it to stay open and often they
do not rapidly close and I end up spilling more gas then the old containers.

That said, the chief enemy of gasoline is oxygen and once any
antioxidant in the gas, like BHT, is consumed the decomposition reaction
accelerates. Most gas cans these days are polyethylene and oxygen can
actually permeate the plastic and get at the gas. The best way to store
gas would be in a sealed metal can with little air head space. Air does
not permeate a metal container.

I get by with 2-3 years adding Stabil in the plastic cans.

There are still vintage gas and oil cans available on Ebay. Dad and
his neighbors used to buy oil from the Farmers Coops in five gallon
cans. The cans were sure handy for other things as well.
