I have five jerry cans. Each one has a number. Every Monday I empty one and go refill it. I know it’s not much, but with a full gas tank and those cans...I can drive to get my daughter and bring her home to the outpost!
Get 12 cans, numbered. First of each month, take the number of the month can and use it. Refill and add Stabil. That way you have 60 gallons at all times.
