Just a side note- higher octane gasoline does not have higher "potential energy". In fact, it's energy content is slightly lower.Depends on how the octane rating is calculated in your area. Here it is (ron+mon)/2. In that case my manual says 89 octane. There's no benefit in using an octane higher than what your engine is designed for because you don't have the compression to utilize the potential energy. Alternatively, using an octane below what's rated for your engine can result in preignition (knock), which can cause engine damage.
Theoretically, you should get more power out of the 87. I would think this would probably only be detectable in drag race along side the identical bike using 89 or on a dyno.I have a 2012 stock Bonnie and have read all these posts about octane and decided to try it myself. I usually put in 87 and decided to try a tank of 89.
To me, it made absolutely no difference, everything was the same, idle, power, mpg... no difference that I noticed.
So, It's back to 87 for me.
Ethanol is just ruining our fun - and making food more expensive. 8 dollars a bushel; farmers can't even afford to feed it to their animals anymore. The byproduct they now feed, distillers grains, is resulting in high mortality and lower quality meat.Then add in ethanol and everything gets goofed up! Argh!
You know what really burns me up? There are no ethanol free gas stations anywhere near me in Northern Virginia, but riding around through the Midwest this past summer, where they actually grow corn, ethanol free gas was available almost everywhere. In my opinion they ought to be stuck with having to buy that stuff!Ethanol is just ruining our fun - and making food more expensive. 8 dollars a bushel; farmers can't even afford to feed it to their animals anymore.
