Default The future of 93 octane

There was story in the news here about people not buying 93 anymore for there cars and it made me wonder what the future holds for it and even if they do continue to offer it at every corner station will it sit there in the tanks so long that you wouldn't want to buy the stuff. I'm running a pair of 720's and I'm not so sure they would like 87 or old 93.

According to engine rebuilders magazine-todays fuels only have a shelf life of 6 weeks from the time it leaves the refinery before it starts to break down.

We're havin a hard time getting 93 delivered to the shop lately , last year they delivered with no prob
Add some Toulene to your 87 and bring it up to 93+ , pick it up at Home depot or sherwin williams has 55 gallon drums

I've definitely heard the same thoughts, but I'm skeptical of that time frame. I've spoken to the 6 different builders I've ran over the years and they aren't that agressive on fuel break down.

Our marina that supplies our 111 Octane, had last years September 07 batch tested in March 08, which yielded 109 octane. They've obviously since topped it off with fresh, but 109 would have been fine for our setups.

I can run 93 on my setup, but run straight 111 for piece of mind, we can't get 93, and of course the fansastic smell!!

Around here we only have 92 octane at BP stations. All other stations have 91 octane at most.

No 93 in Oklahoma. The best we can get at the pump is 91. It sucks too cause our Mazda Speed6 is supposed to run on 93 and the boost gets pulled out by the computer with 91.

Yeah, my 600 needs the higher octane. Same with my jetboat.... and Viper......
My favorite marina used to have nothing but. Just two weeks ago, they switched their operation over to 87octane to offer cheaper pricing.
Is this a sign of things to come? is 92-93 octane going to go away? or skyrocket? It's not looking good. WTF!!!!

92 and 93 for that matter have been gone a long time in CA. All we have at the pumps are 91, 89 and 87.
