Are you are suggesting use Stabil if it will take a month to use up a tank of gas? Even 100% gas?

I doubt stab-bil will provide much benefit if the gas is only a month old.
But we don't know how long it took from the time it was refined, blended, shipped, delivered, and sold to you.
Usually refineries can't sit on a tank of finished product for more than a week or so depending on their tankage capacity. High volume high turnover.
So let's say that took a week. then it was shipped to a distributor, and maybe it sat for another week. then it was delivered to the station, where it was mixed with gas in an underground tank that had been sitting there for a couple weeks, and it sits there for another week until you buy it.
That gas is nearly a month old when you filled up worst case scenario.
In your case making sure yo go to a high volume dealer is even more important.
Joe's fillin' station out on route 9 where they sell maybe 200 gallons a week is probably not the hot ticket.
Not sure if filling all the way up is a good idea or not in your case. some folks say a full tank is better because it reduces the amount of vapor space (air with humidity). Can't speak to that specifically. I'd prolly go with half a tank at a time if I were you and you're glad I'm not.
Pure gas is good, alcohol absorbs moisture.
But does it have any oxygenated additives?
MTBE was a famous one and it absorbed moisutre, ethanol does the same. if you can get pure gas with no oxygenate that's better for longer term stability.
Then again, sta-bil is relatively cheeep and a couple ounces won't hurt ...
