Unless its got a turbo or supercharger on it, save your cash and run it on 87 octane regular. SA/FB/FC series & old school normally aspirated rotaries will all run fine on the lower octane stuff. Not as sure for the Renesis RX8 engines, as those run higher compression ratios, and may require the higher octane fuel like a turbo would.
