89 and 91 octane. Wow. 91 is the base grade out here with 95 and 98 being the options. We also can get E85 which is 85% ethanol, not some ugly Euro 85 octane stuff. Cars need a complete re-tune with bigger injectors and a programmable ECU for that. They also usually run an automatic detector which identifies the fuel and then runs the ECU maps to suit.
