By the time the fuel is in yer tank the octane rating is not what it started at... esp the more expensive fuels that are not replenished as often at the servo.... std fuel is turned over quick & more likely to have a closer rating to what is stated.
We still use BP100(Leaded Avgas) in the sidecar under a special MA & govt licence, & the quality is nothing like it used to be due to the fact that the small QTY that is manufactured sits around a while before being used...BTW thats not the avgas that planes use.

Octane for me.

what are the differences in performance???
i went to the servo today to get petrol but didnt have the balls to go back down to 95.

id say minor, perhaps a slight smoother run if yours is a high octane engine. f/all if your talking about a zzr250 engine though.

If your way paranoid you can always run about with a bottle of octane booster in your tank bag and tip some in if it goes shoddy (or as i did, kept it with me for the way to philip island and poured some in when i filled from a in-the-boonies station.
