100LL stores poorly.

I don't know where you're getting that information. I have used 100LL that was well over 3 yo with no problems.

Note, if you use any leaded fuel in a catalytic equipped vehicle, it will coat the converter and prevent it from doing what it does.

TurboZamboni, only use tightly seal-able, strong metal containers if storing fuel in high temp climates.

I like military jerry cans.

I worked at a FBO in the midwest and storage of 100LL was never a problem even after years. Some people purchased it just for that reason, to store as an emergency fuel.
