Switching to E85?

[Thor06]

You do realize that you need 30% more fuel for the same amount of air, right? The cost savings is minimal, but the extra power is worth it. Back to your search.
Is there even a cost savings? I've been wondering about that recently...

Nope, it is cheaper than running race gas everyday, but it will cost more in the long run than premium. If the price of premium gas ever got well under $2, then you might start coming out ahead on E85.

Someone put the conversion up a long time ago to figure that out exactly, I forgot it though. I know up here in Blaine E85 is 85c cheaper than premium. I personally don't use it to save money over premium. I use it because it's a great compromise between price and performance.
