87 Octane, unless you've installed a turbo. ;]
93 octane
87 or higher but the manual says 91
you should use the medium rating octane(may vary depending on station)but usually 89 octane
" regular " unleaded , 87 octane
87 octane should do fine. If you find it knocks a little then go to 89 octane. You can always use 91 octane, won't hurt, just in the pocket book.
Premium unleaded 98 Octane
normally it runs with 87 octane gas... i always use 91-93 octane is more expensive but keeps the fuel system cleaner and healthier
Any. Tiburon engines do not require high-octane gasoline, although it never hurts.
Most professionals recommend that you use high octane gas. Like 92-94 octane.
87 octane is good for 3.1 but if ya want to use a different octane it wont hurt.
You should use 93 Octane in your bike.
