Basically answered all my questions -- I don't necessarily agree with it all, but it's a good discussion. For example, it's very difficult to oxidize a hydrocarbon without enzymes, catalysts, and the like. And I don't think the "lost volatiles" in old gas amount to much ito performance.
Bottom line is, I don't think "bad gasoline" ito age is much to worry about. After this bullshit with Sandy, NOW we got a gas crisis, so ahm fixin to store a bunch. I figger I'll "exchange" it yearly -- it's own pita, but it beats waiting 4 hours on line for 10 gals of f****ng gas.
I used to scoff at survivalists.... but not any more. I'm realizing that urbanites/surburbanites are essentially walking around with their cheeks spread.
