You're Octane Rating in Australia is done differently. Your 98, = Our 93.

Either way, just get the cheapest gas you can find.

The higher the number, the longer it takes to burn, and the more resistant to

pre-detonation (knock). Because of the design of the rotary's combustion chamber,

a longer burning fuel will still be burning as the exhaust port is uncovered, causing

even higher exhaust temps than normal.

Then you start to run into timing issues with the tips of the rotors at higher RPM.

And as stated above, it's not necessary unless you're boosted.
