I think that often as important (or more important) than the octane you're running is...what's in the fuel you're using.
While I appreciate that many riders have no other option than to fill up 'direct from the pump', I seldom do. It started out when I began racing - I'd always fill up several fuel cans for the race bike and there was always some left over, so more and more often I began filling my road bikes from the cans, always using a filter funnel.
Regardless of where I'm buying my fuel, you'd be amazed at the amount of crap that is in fuel. I've seen grit, organic debris, even metal swarf and rust flakes caught in my funnel filter. I never empty a can to the very last drop because there's invariably crap that settles to the bottom and often water, too.
Service station tanks are almost always full of crud. If your bike is more than 6 months old and like most people you are filling direct from the service station pump into your bike's tank, take a flexi light and a stem mirror and have a good look at what's in the bottom of your fuel tank. I promise you'll be horrified.
