(I hope this is posted in the correct place.)
Thinking I was prescient, I've had this portable gas container in the garage for 'emergencies' when I needed a little gas fast. Of course I never needed it, and it's now been there for 3 years. I put stabilizer in there before the end of the first year.
My question is that even with stabilizer, does gas still lose it's octane (just takes longer I would guess), or is this gas still ok to use?

The maximum limit for gas with fuel stablizer is 15 months..... The gas you have in that tank should be close to varnish..

Stabilizer must be added as soon as you buy the gasoline. The "lights" start evaporating away immediately and, as I understand it, gasoline has undergone a pretty dramatic change in its chemical makeup after 30 days if it didn't have stabilizer added to it immediately.

The problem with everything said so far is that it does not take into account the fuel stabilizers that are added by the refiner. Pure gas (no stabilizers, detergents, etc.) starts to lose octane very quickly and stabilizers are needed. How long do you think the gas you get has been out of the refinery? In the best of cases you might get gas that is a couple of days old, but I would bet that a large volume of the gas for the public market is over a month old.
I have used gas that has been stored for over 18 months, in drums, that is indistinguishable, in appearence and performance, from new gas. Without added stabilizer, fuel stored in a fairly full and air tight container will last for at least two years and certainly longer, probably much longer.

"Some fuel system metal components will rust or corrode in the presence of water or acidic compounds. The additional water dissolved in oxygenated gasolines does not cause rusting or corrosion, but water from the phase separation of gasoline oxygenated with ethanol will, given time."
"When gasoline is stored for longer than six months, or when storage conditions are not favorable, monitoring existent gum content may be necessary to make sure the stored gasoline will perform when used."
Unless you are going to monitor your stored fuel for "phase separation" and "gum content", as noted by the gasoline manufacturers, use a stabilizer when storing fuel. The caveat is that the stabilizer works best if it is added to the fuel as soon as you buy it.

Use it in your lawn mower or some other low compression four stroke, or put in in your car before your next fill up. It'll burn alright and it's better then dumping it somewhere.

Info pertaining to how long gasoline can be stored without deterioration:
"Chevron gasoline can be stored for a year without deterioration when the storage conditions are good -- a tightly closed container and moderate temperatures."
