I started buying a lower octane and I was able to get myself a new grill with diamonds, and I put my first kid through college...

Redic, lol. I use 87 after I've done research on gas.

yea but too bad they keep reproducing...
see voodoo's post above...muahahhaah
it's good stuff when you back the claims with engineering facts, etc...and not..."well...i think it shoud use this because it's high compression, blah blah blah..."

there is a wide spread notion that higher octane = faster no questions asked.
This gets reinforced in movies and video games. I think there is a game called 'high octane'.
It's natural for someone that doesn't know the science behind it to jump to that conclusion.
I admit when I first got my bike I thaught putting high octane in was better because someone told me it was.

thing about all this, dont put a higher octane in ur bike if there isnt a need, if ur gonna be racing ur bike on tracks days then get the higer octane, less of a chance of knocking and let it be easier for the fuel to burn. i run 89-91 round town and 100-110 track days

I actually asked Tahoe (I think) what he runs at the track. He doesn't use a higher octane while racing. That speaks volumes to me. Do what you want...this is a debate that reminds me of "the chicken or the egg".

- High octane fuel will not burn "hotter." Did you know that methanol has a motor octane of about 115, yet little more than half the BTU content of gasoline? Compressed natural gas has an octane rating of about 130, but 1/4 the energy content by weight of gasoline. Pump gas has a negligible difference of energy content between the grades. I failed to see how octane rating of alcohol and cooking gas has anything to do with the octane rating that is used for driving. Alcohol and gas not only have difference chemical structure but also they have different compositions from the gasoline; therefore, they will have different applications and results.
Also, if the difference between the grades would be negligible then what would be the purpose of manufacturing those other grades?
Im not calling you out but, Im just curious on what is your basis for your argument?
You guys can do what you wish with your bikes; there are no rights and wrongs. The ultimate test is trying it out for yourselves. I have used every grade thats available in my area (87,89,91,93) and if you are telling me that from a higher rating there should not be a difference in heat produced then I'll bust out the thermostat from my turkey and a stop watch, may be video tape show fast the bike will heat up and how long it will take for the bike to cool off.<naturally Im not going to do that.
Still, Im surprised that this tread is still growing. Most likely no one cares but I use 87 and sometimes 89.

I once tried 110 with booster and I went 440 mph. Blew the decals right off my bike.....j/k
I was told octane needed is mostly determined by engine compression. F4i stock engines will only waste unburned fuel with anything above the 87/89 requirement. This was from a factory race Suzuki mechanic.
Anyway.....
If I can use 87/89 I'm going to.
(I'm a cheap b^$*%rd)

I know what I misspelled. I didn't bother correcting it because I had already been quoted by Tahoe SC when I noticed. The "ignorance" comment was in reference to his signature. It wasn't me trying to sound superior.

Like I said, octane is not related to how much actual energy can be released by burning a gallon of fuel. The octane ratings between 87, 89, and 91 are obviously different, but the caloric contents are very similar. Also, octane ratings are octane ratings regardless of what the fuel is used for. They are only used to describe a fuel's resistance to knock in an internal combustion engine.
