Your spot on ethanol fuel is hell on the fuel system many new cars are going through fuel pumps at a high rate of speed the pro ethanol people say it’s only because people let their tanks get lower than 1/4 of a tank BS ethanol is crap.
Yes you cannot store any ethanol based gasoline, its possible to pump out any airborne moisture and store it but its been found that after a modest amount of time usually depending on the climate that the ethanol separates from the gasoline and changes to the point that it will not re-mix.
Forget about stockpiling it, it would be worse than dated ammo.
A person could possibly believe in a conspiracy theory about this, America has to buy it, has to use it or it will break down into a chemical that’s useless.
Worse than being hooked on cocaine.
