Depends on how much and how long and how portable.
Most folks can readily carry a 5 gallon plastic or metal container
Few can carry a 10-15gallon container. They usually have wheels.
No one can easily move 55 gallons of any liquid including gasoline unless they have serious mechanical aids.
Net: 5 gallon containers are quite practical. Put Stabil or Sea Foam or any variety of stabilizers in the gas if you intend to store it.
Think about how you will get the gas to and into what needs it. Again I bet the 5 gallon containers are the best answer for most folks
thanks, that is what I have, but just a few jerry cans.
I was wondering about a buried tank that would be filled over time by repetitive trips to the gas station
Marine Sta-Bil is widely thought to be superior to the regular stuff. Available on Amazon if not in your local Wal-Mart or auto parts store. FWIW
Ah, yes, the Mad Max method.
