Hard to find 93 octane around here anymore.

If you have a Pure Stocker, NHRA rules should be no issue anyway. :-)

Tow with a 94 beefed up Caprice wagon.
Iron Head LT1, 87 Bryan Herter Performance Tune with no problems.

Towing over Appalachian Mountains fill up with 93
Flatter land routes such as Capitol, MIR, Cecil 87, etc works fine.
Hot days use 89 or 93.

Since GT, CM or Stock require approved fuels.
Own a home in Suburbs.
Considering buying about 10 cans of Sunoco 260 GTX for a season.

How and what are the best practices to safely store this fuel?
I know my wife will be concerned.
