93 octane Vs. 110 / 112 octane?

Ok I've seen many debates on here about the benefits or lack there of using 110 octane gasoline in a sport bike. I have filled up with 50% 93 and 50% 110 and noticed a significant increase in throttle response. The bike just had more kick to it than when I just use 93. Every other rider I know who has done this, reports the same effect. I was cheap one weekend and I filled up with 87. Good lord the bike almost didn't run. If performance is affected from 87 to 93, then why not from 93 to 110 or 112? So does 110 and 112 octane gas improve perfromance over 93 octane?

Octane only indicates the resistance to pre-detonation. If your motor is prone to such (high compression, advanced timing, carbon build-up) than yes...you will see improved drivablity with higher-octane.

But don't get confused, you aren't "gaining" horsepower, you are "reclaiming" lost horsepower from bad fuel.

You bike will probably not like 112 octane unless it's like 13:1 compression. You just found the sweet spot with what your bike liked to burn.

You should run what you manufacturer suggest to run. Some bikes recommend 87, and if you run any more than that then you run the risk of fouling the engine and ultimate damage.

Higher octane does not necessarily mean higher performance but in many cases it does and offers better gas mileage. So for a high performance engine, great, but if it was not really designed for super high octane, you shouldn't use it too often else you'll causes some problems.

110 and 112 octane gas is getting into the aviation fuel category. Aviation piston-type engines have to run high compression and supercharged because of thiner air at high elevations. And because those engines have to produce a lot of power in small packages - doing so for thousands of hours.

Higher the octane means that the fuel is less prone to detonate. Makes for a slower but hotter burn. You could cause heat damage if your engine is not designed or refitted for gas of those kinds of octanes.

i run unleaded 110 in a gsxr 750. never had a problem 13k miles she loves it. big difference from 93.

I like what the other guy said about it not a boost in power but maybe reclaiming lost power. I use 110 only occasionally in my 750 sport bike. Haven't had any problems yet.
