On my 97f3 there is a sticker under my seat that says you should use 91 octane fuel. I would never use 87 unless I was stranded somewhere.

 

I'm gunna check this out today(not yet tho its 43 degress outside right now ). I know the owner's manual says on page 32 to use 86 or higher.

Wish, I'm sure it won't effect the oil companies either way. My guess is that when the gubbmint implemented the 10% rule, the big oil thugs just bought half the corn farmers anyway... lol.

That is correct. The F3 doesn't require premium gas.
And xricer... before you think we're crazy (or that you're crazy), your bike probably does have a 91 sticker on it. However, it's for 91RON which equates to 86/87 octane in the USA. We use a different system here (AKI).

Although...... this thread has nothing to do with octane values at all, just ethanol vs. non-ethanol fuels.
