Everyone is talking about this possibility of a knock with the 87. If its not bad to run the 93, and you get no knock, then why not do it. Think about it, were only talking about a few gallons here. At my gas station, the 93 is about .20 cents more a gallon than the 87, so to fill it up what are we talking about....one dollar? As long as the 93 is ok to run, ill stick with that and pay the extra dollar, besides i dont have to worry about, or listen for any knocks.

I have never had any kcocking or pinging on 87....just so you know there is a downfall, I don't know how much you loose, but by running the higher octain, you are loosing power.....

lol im not saying running higher octane or anythign cuz it doesnt make a difference but if you put higher octane in there it doesnt make you loose power. i ran 110 leaded in mine and dynoed it and showed a 3hp increase over the regualr gas so i beg to differ and wish i still had my damn sheet to prove it but you will not loose power by running a higher octane. are engine are made to run on 87 but are also made to run on race gas hence improving the overall performance of the engine. ima get it re tuned and dynoed again after i get my header and will save the damn slip of regular to a higher octane gas

Ok fair enough, but you are also comparing a bike that has been tuned....not sure what all is done during the tuning, but if something as little as spark advance is messed with you no longer can compair...the more octain, usally the further you can advance the spark. Run a lower octain with an adavnced spark and you get knock. The higher the octain the slower and cooler the fuel burns....that is all I am saying....

87 octane, no problems thus far.

Just out of currosity, What fuel are you running in your bike. I have an 01 F4i and have been using 93 octane which seems to be running good. I dont have the owners manual so if someone with an 01 could tell me if im not supposed to be running 93 please post it
ITS MADE TO RUN ON REGULAR!  ... why is this a 2 page thread?
When did the thread change to "What will my bike do on race gas?", or "Tell me where you get your gas" 
Its not going to hurt the engine if you run a higher octane... it wont make you loose power... it actually makes you run a cooler temperature. Its cleaner... Unless your running a higher compression, or an advanced timing, you don't need higher than regular!
All the guy was asking, as seen above, was what gas is the bike supposed to run on because he didnt have the manual when he got his bike.

lol ya i agree with u ghost & rather, k ya i get my gas from a sunoco in my are that sells 100/110/120 gas so when i go to dick around on my crappy backroads i get that. but u guys are right it got to a race gas thread, if its not tuned and just stock u can run either or gas it doesnt matter. since i upgraded the exhasut and pcIII and filter if i put in 87 it runs sluggish and like pooo but when i was running stock i ran 87-93 and not much of a diff.
so to answer the question for the main thread run whatever you want it wont affect it at all, lol but if u get a chance throw some race fuel when ya can even stock youll notice a diff with it and plus the smell makes you fell all good and ****

Yeah, I normally just run 87 in mine. But my Dad had 110 from the local Sunoco, and wanted to put it in my bike for shits and giggles. The smell after it burns is definately addicting lmao. And it leaves a white residue on the exhaust tip instead of that black. I didn't really notice that much of a difference if there was one though.

I don't understand that rationale at all. If you don't need premium fuel, pay more for it anyway and leave a little power on the table just because you can? 
For those saying that premium is cleaner, cooler burning, hotter burning, slower burning, resistant to burning, or whatever.........it is none of those things. Here are some excerpts from posts of mine in a few threads just like this one:
quote:

Also, octane does not refer to the rate of burn or flame speed of a fuel. It describes a fuel's resistance to autoignition. Methanol is ~115 motor octane, but it has a flame speed that is faster than gasoline. High octane is great if you need it, but it will cost power if you don't.
That autoignition can come from heating due to compression, residual heat in carbon deposits, radicals in exhaust byproducts left over from the last cycle, and even too much ignition advance. However, spark knock doesn't quite work the same way as flat out autoignition.
quote:
ORIGINAL: 65ShelbyClone
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.
The bottom line is that the F4i's ability to run on 87 R+M/2 octane fuel shows how conservative Honda and/or Keihin was with the ignition advance curve. This is especially significant considering there is no knock sensor. Another aspect of being able to run 87 fuel through a 12:1 engine is the relatively high rpm. There is simply less time for the necessary chemical and thermodynamic reactions to take place in the cylinder. An efficient chamber design also helps. I suspect that if Honda had taken full advantage of their design, none of us would be able to run anything less than 94-96 fuel.
Now that we have yet another beaten-to-death octane thread, all we need now is another "what oil is best" thread to complement it.
