The longer you can go without gas, the wiser it is to fill up at once. Currently, I only buy gas every 3.5 to 4 weeks. Utilizing two 15 gallon Jerry Cans, that could probably safely be brought up to 12 weeks. It's common knowledge that gas degrades over time, but I think it would be fine if kept in an airtight container located in a cool spot. There are probably other cheap/free techniques in stabilizing gas that could be utilized without negating potential savings.

If you can hold out 12 weeks, you can easily get through the summer driving season. The summer driving season is always more expensive than any other season, so there wouldn't be much price guessing. You do have to deal with 30 gallons of highly flammable gas near your house and the risk of losing meager savings due to evaporation/degradation.

Personally, I just buy gas when I'm on empty at the cheapest station along my commute.
