Just curious if anyone has experienced any differences in premium vs. regular fuel.

You can run on "regular" gas if putting around, but if you run it hard you can damage your engine. I'd never put anything but premium in my bike. Never ever.

The dealer told me to ONLY run premuim. Sometimes i have to fill up and the gas stations in the middle of nowhere only have reg so i throw in some octane boost

Premium when they have it, but sometimes unleaded 91 but I can't tell the difference.

91 is Premium around here.

do not use octane boost in these bikes the stuff in it can hurt th o rings in the high pressure fuel system is what iwas told (from this forum)

Premium.. but not Shell Optimax..

Why not ? Is that the one with ethanol added ?

Tend to use 98 from Caltex.

93 Premium for me.. The warmer climates (closer to sea level) should have a higher octane premium whereas when you go north (like Utah), the premium has a lower octane.. Hard to believe CA (as posted above) would have 91 octane.. The higher the octane, the slower the burn which is needed to avoid detonation in higher compression/performance engines. If you have modified your engine to have higher compression ratios, you would want to put race fuel in it with even higher octane levels..

Premium only! Never filled up with any thing else.

93 Sunoco most of the time....94 Sunoco when I can find it.

 

[ohioVROD]

BP 93 or Shell V-Power

I never worry about the octane ratings. I just use the best that the gas station has.
