I'm convinced that running on higher octane premium when your bike runs fine on regular gas is a waste of money. I found this seemingly authoritarian article to explain why.

I guess its a matter of personal opinion.
I don't understand why you care so much what others run in their bikes...you keep quoting other forums and Wikipedia........who gives a shit! Just ride the damn thing and enjoy it!
This was a thread started on how many gallons is a full tank...not what gas they run...the only reason I brought it up is because I have physically seen a side by side....and they are different....simple as that.
I hate to unnecessarily argue (actually, sometimes it is fun), but it really isn't. It's a matter of fact. There are a number of sources which explain in-depth about what octane rating really is.
Unless your engine is specifically designed for it (ours doesn't) and/or it's a high-compression engine (high compression ratio, or forced-induction), there is absolutely no need for high-octane fuel. The exception to this is if your engine pings/knocks (which if it isn't designed for 87, there's probably something else to blame for that and should be checked out). That is a sign of detonation, or fuel igniting before the spark goes off. That can cause major damage to your engine if it is severe, or run that way for a long time. However, if your engine is not severely knocking (it's hard to not notice that) there is no reason, other than wasting money, to use fuel over 87-octane.
See the bottom of the Wikipedia article for sources.
Have you run the 2 different octanes in your bike? I have have and there's a noticeable difference. At least when you give her the berries. If your just putting down the road at 5k then there's no real difference probably but I ride heavy on the throttle for the most part

I usually gt about 180 miles on a tank. I actually got a little lover 200 one time, although it was completely empty when I finally got to a gas station to fill it up.
But as for the octane discussion- the knocking thing with low octane fuel is not so noticeable anymore with our computer controlled engines because they have anti-knock sensors which immediately retard the spark, and the engine doesn't knock.
So everyone who doesn't understand that thinks their engine doesn't need high octane fuel, and in a sense it doesn't if you're just keeping up with traffic on the freeway. You won't notice it in low power, cruising conditions.
However, spark advance is where you get all the power in an engine, an old school drag racer once told me, and he was right. You get the pressure in the cylinder for the entire stroke of the crank, not just 3/4 of it, like when you retard the spark. You can get more power out of the engine when you are using high octane fuel.
If you really want to check this out, find a buddy with another FZ8, one run 87 octane, the other 91 octane and do some side by side tests...
