Wow, really surprised you guys don't add octane booster if all you can buy is 91 RON fuel..... I used to run high powered Subaru impreza's years ago..... even added octane booster to 98 Ron fuel then to avoid detonation which still used to spike occasionally on the knocklink..............!!!
Just goes to show how misguided drivers are generally around the world I guess...( by car manufacturers )
