Speaking of gas cans, I started doing this a few years ago.
Every month for a year, about the same time of the month, I'd buy a 5 gallon gas can. I'd mark it with the number of the month I was in (Jan = 1, Fed = 2, and so on). I'd fill it up and place it on this heavy shelf. The following year, I'd take that can, dump it into my truck, put the can in the back, and head to the gas station. I'd fill the can, and fill the truck the rest of the way.
Now, I have 60 gallons of gas on a monthly rotation that is never over a year old. No need for stabilizers or additives. No extra cost (after the purchase of the can and the first fill up) since I burn the fuel in my truck anyway.
A few years ago, we had a horrible wind storm that knocked power out to the majority of my city for about a week. People were lined up down the road at the only fuel station that had a backup generator. I simply drove past the line. 60 gallons of fuel kept my generator humming and my vehicles running.
In the photo, you'll see a can marked with "M". Thats for Miscellaneous. This gas is not on rotation. I use it in the lawn mower or to mix 2 cycle with.
