Use a fuel stabilizer product called STABIL mixed appropriately to stop the
breakdown of the gas. Plastic containers are fine IMO for short term storage.
Getting gas for the mower, or helping start a vehicle out of gas. Anything
needing to be stored longer, weeks or months should be in a metal container.
Metal storage containers being better for long term as there is less oxidation.

I'd store the fuel in the shed, away from the house. Not the garage
if you can use the shed.

Not the usual question as, how long, how, etc.?
I use the same mixture for my Toro Mower and my Craftsman Line Trimmer. I keep
the mower and the fuel in my back yard shed, and the trimmer in the garage
because I use it 90% of the time in the front of the house. The trimmer holds
less than a pint of fuel and doesn't get, shall we say, good gas mileage.
OK, TOM, CUT TO THE CHASE!
I frequently have empty gallon containers that come with the Torch Fuel I buy
at the world's largest XXX-Mart store.
OK, OK, here's my question!
Can I store some of the fuel mixture in the garage in one of these gallon
containers? Say about two quarts. I'm not interested in the legal aspects, just
wondering if the fuel mixture will "disolve" the container resulting in a leak.
Thanks for you patience in scrolling through my question to get to the point.
