I usually keep three 5 gallon cans on hand. Stabil before filling them, they last a long time. Which reminds me, I need to fill them up, winter is setting in.

I use them in my riding mower through the summer, and re-plenish so they never really go bad.

Also, pick up the large bottle of Stabil, it will last you a long time.

With my truck, I can fill one tank @ 16 gallons, and get a ways out of town, but figure it would be a worthless try. (12 mpg downhill with a wind)

I plan to bug in, sell my gas for $200 gallon to those trying to leave.
