Well I can tell you the more ethanol content in the mix, the faster you will need to refuel. Ethanol also burns hotter so the more ethanol content, the faster your bike will actually be.Hi: I should probably do a thread search for ethanol to see if the topic is already covered. But what has been the expereince with this fuel additive/replacement? Don.
Octane is a heat measurement. Higher octane really does = higher speed/acceleration, is it good for your engine? absolutely not. Even engines that claim they can run 100 Octane shouldn't be run that way often, high heat = engine strain.
On the other hand, engines that claim they can only run high octane should be run at the octane rating... but it will most likely not mess the engine up permanently. Like a Mercedes car, you can run 87 octane all day long with it, it is not recommended because the engine will not run as smoothly and eventually sludge will build much faster.
Still waitingAnd for those that swear Premium (or high octane) fuel makes their stock KZ faster, do a Google search for something like "High Octane gives better performance?" and see if you can find anything that supports your opinion.

Octane rating - Wikipedia, the free encyclopediaThe octane rating is a measure of the resistance of gasoline and other fuels to autoignition in spark-ignition internal combustion engines.
:wink: "Spot On Mate"Octane also does not boost heat but actually retards the flame speed so preignition is less likely. Lower octane fuel burns more violently so is more suceptable to pinging rattling knocking, so if you have any of those problems then higher grade of fuel will give more power.
