umm. you question does not make much sense what do you mean? Are you refereing to a fuels octane rating? and what do you want to know about it, all an octane rating is, is a measure of the fuels resistance to detonation.

I know what octane is.

I'm asking if i take 91 and leave it in my car for a month... is it still 91 or does it deteriorate?

A month is nothing. Long term storage is another issue. If you are worried about it buy some STA-BIL.

Examples?? I have it in all my lawn equipment and my neighbor has 14 collector cars with it in each tank. No issues and perfect gas. They are a well-known product used by thousands and thousands of people that own EXPENSIVE collector cars. I sure want to hear about it as would the company.

I put 3 gallons of 100 and 2 gallons of 91. I only drive my car around the block like once month. How long should this gas be good for?

Hey Dakota, getting an LQ9 and a cam soon ;)

LQ9 is actually on the way to Sean's shop, waiting for somebody to buy the LS1 out of my car :P

Without Sta-bil I would get nervous after about 4 months. It helps being out in AZ I would think without the moisture issues. Probably won't hurt anything up to that point, but after that....

Yeah if you really drive it that little you should use some type of fuel stabilizer. btw your sig made me :lol:

I've still got half a drum of 111 octane but its about 5 years old. Probably only useful for starting the burn pile now :(

thanks, not many people down here build 6 speeds for launching

I would say, 1 out of every 100 can launch. you are that one :devil:
