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

i run 93 if i can get it 91 if i cant..

my owners manual for my bike says to only run 91 octane or higher, and that running anything less could cause a knock.

87, the bike is made to run on 87 pump octain, running anything higher is a waste of money and you are loosing power, not gaining it.

Octane is the resistance to burn so you don't get preignition or detonation. I usually run midgrade. Which comes out to 89 octane I believe. According to the oem manual it says run 87 octane and if you experience knocking or pinging then put a higher grade in it. In F4i's it is a waste of money to run premium if you aren't experiencing knocking or pinging. I would start at regular unleaded if you start to experience knocking or pinging then bump it up to midgrade. A little bit of knocking and pinging for the time being won't be a problem, it's if it keeps occuring for long periods of time do you start to do internal damage.

umm i doubt running a higher octane is gonna make your bike "lose" power.  People dont pay more for better gas to get more power, if anything it's just running cleaner.

You will not lose any power by running a higher octane fuel.  As per higher octane fuels being cleaner or even "Name Brand" fuels being cleaner, I dont really think so.  To answer the original question,  I found out recently that I have a VP Racing gas station a couple blocks away from my house. (Good for my turbo charged DSM)  They sell 100 and 93 octane fuel out of the pump.  I've run 100 and 93 with absoulutely no difference except the amazing smell that 100 octane puts off, it should be a colonge, equivalent to sex panther.  I usually run 91 (standard premium in the great state of Nevada) and no problems with it, but I'm going to go with 87 if I dont get any knock with it.

GENERAL RULE...go lowest without knocking...if it does...then go up.

now as for higher octane producing less power...we would really need to see a dyno comparison of a bike that doesn't ping at 87...and then runs 91...and compare...common sense would say that there is no power to be gained (bike has dumb ecu, no sensors telling it to advance timing or back off timing, etc.)...but as far as losing power...i guess it is possible if you go super high octane and the fuel doesn't burn completely.

100 octane does smell great...i don't know about a cologne, cause since chicks don't dig the smell, you'll just be attracting guys...hahahhahaha...
