It requires RON 95. Our Regular is Ron92 and Hi-Octane is 97. Depending on how much fuel you're getting you have to calculate the ratios each time you fill up. IMO, its not worth it, just get HiOctane
People coming up with their own experiences of 1 tank on Hioctane and 2 on regular, dont listen to them. The engine has anti-knock sensor so suppresses the knocking but that means reduced engine power. Will probably have long-term affects on engine as well.
