Does octane go down when gas is stored?

Just curious.
If you store gas in five gallon plastic jerry cans, will the octane level drop?
If so, how much?
Reason is I live in a rural area and when I go to the city I pick up a couple cans of 94 octane premium to take home with me.
The best we have here is 91 and some resorts and marinas say it's 91 but it's really only 87!!.

Turns to crap at some point! Buy the fitch fuel catalyst! I have 2 in both tanks of my sleds!
Keeps the gas the same forever! Acually increases octane over time! Snow tech mag is where I first read about it they have some in every fuel container they have Well that is what is in print! Do a google search about the Fitch fuel catalyst.
 
I stored both sleds in the trailer without taking the time to add anything to the fuel. Pulled the trailer to Cooke City last week and spent day one getting 2 sleds running. I was sore on day 2 of the trip from pulling on a rope instead of riding. The fuel would not support a flame. Had to siphon the fuel off, remove the carbs and drain the bowls. Fresh fuel made all the difference. Its a lesson I have learned before. After a time, fuel turns to something other than fuel.
 
I have never had a fuel related issue using stabil fuel stabilizer.I usually run it low and fill it with fresh when its riding time.I'd like to try the fuel catayst at some point.

Same here... if it's going to be awile before you use it get premium
and put some stabil in.

not shure if oct. goes down with time, it probobly does but how
long dunno..
 
Yes octane definately does go down as fuel sits, but with a shelf time of only a week or two you will be fine and won't even notice a difference. Two, three, four months and you will start noticing loss of fuel quality and potential detonation, especially if the engine is modified for more power (more compression, pipes, etc)
 
Fuel

kysledneck is right, by the "Fitch Fuel Catalyst".
Stored my sleds last fall with the fuel catalysts if both sleds. Had a hard time starting both of them because I was to lazy to drain the float bowls. At first they both ran real rough and would hardly idle. After about 5 minutes when fresh fuel got into the carbs the idle smoothed right out and these things run better than ever with last years gas in. Amazing. These things do work as advertised, Fitch has a contract with the military, and the military usually doesn't buy anything unless it's proven a few times over.
Next spring I'm draining the float bowls and that's it!
