Here is how we do it. We have 5 each 5 gallon Jerry cans which we fill with premium grad gasoline. We add twice the recommended amount of Sta Bil to it. Then we rotate it every 8-12 months by using one 5 gallon can per vehicle. Just add it to a half full tank and top off with fresh gasoline.
We have never had any problems.
Using premium is a good point because you can afford to lose more octane points for regular-requiring engines. P.S. Thanks for the link the other day on the home generator setup. I still have my disposable consumer-grade 3600 rpm generators. They only have to last through the amount of fuel I have stored.
