    Which octane level should I use for my 2000 gsr? I use 89 now but i read up on a site that said gsr's should run 91? Is it okay to run 89 or should i always run 91?

    if its not pinging then you are fine

    if you will be doing a lot of hard driving i would go with the higher octane just for the added insurance though

    At least 91. You can't find 93 everywhere.

    i kinda mislead him. I don't have a GSR, so I can't tell for sure, but if E and NoJoke say you can use 89 (and not ping) then you can use 89.

    What I was saying was if you do use 93 like Milan says, then 91 would be safe as it's in the same group of premium as 93 since a lot of stations won't have more than 91 octane.

    On a just thought up question...how do you figure out octane ratings? r+m/2 is the formula...but what does it mean?

    What about a b18c5? 93? Will running racing fuel (100 - 110 oct.) damage anything?

    i run 93 on the street in my ITR engine

    i run unleaded 100 octane when im at the track though

    when racing balls out for 25-35 min its a little added insurance :shrug:
