Which Octane?

**drtbkeryder4** · 26th October 2006, 14:39

Hi, this is kinda a silly question but anways here goes. I've just bought a 1999 Suzuki Bandit GSF250 and before it arrives I'd like to know what kinda fuel these bikes were made to run on, 91 or 96? I know it should run fine on any of these but which would be the best to use for everyday sorta use. Cheers guys

This subject seems to come up every now and then. From everything I've read about it etc; it is a waste of time putting any more than the regular in it, unless the manufacture specifies a higher octane must be used.

ok then, cheers mate. 91 shall do the trick then

91 will be fine.

..would this apply to most/all bikes then? (excluding, high performace bikes etc)

just plop 91, in it.

So when I'm riding my crappy old GN around, is it just my imagination that when I run it on 98 it has slightly better pickup than 91? I coulda sworn it was better, amazing what imagination can do.

I just won the 6 round Actrix Senior Post Classic championship on my ZXR750 running on 91.

dizzam, I was told by the previous owner of my ride that premium was what he put into it, good enuff for him, good enuff for me! So... waste of time putting in the more expensive stuff?

Many would disagree however. Is that from personal experience CS? I know guys who run 91 in their sports bikes with no dramas. Not me however, my bike prefers 96.

91 my ass... sluggish like a bastard on 91, won't touch the stuff... 95 is ok, but I'll run it on 98 whenever possible.

Seriously, run it on a tank of 98, then try stepping down to 91, it's just painful.

You'd have to have a pretty radically worked high performance bike to need more than 91. The only bike I've owned that specified 95 Octane was my TRX, but then it depends on what Octane rating you are talking about RON or DIN?
