a few people have told me that 93 octane gas will loose its octane if not used within a month or so others have told me it rotts or goes bad in a few weeks how true is this? or is it just a bunch of crap

Not an expert and perhaps others can chime in with better info, but my understanding is that commercial pump gas only stays 100% fresh for about 2 weeks. It doesn't magically then turn into paint thinner on the 15th day, but it begins to break down.

I use Sta-bil when storing cars or I try to get the tank as close to dry as I can, then add gas from a can when I take it back out of storage for the drive to the gas station.

EDIT, in the "old days" you wanted to fill a tank up to the max before storing a car so that rust could not form in the tank. My LS1 cars have plastic tanks, so I don't worry about that anymore.

You were also dealing with leaded gas back then too..

I read somewhere that the e-10 gas is very prone to alot of condensation more so than pure gas. It is also more corrosive to the fuel system when it is not used soon.
