Truth is, unless you doing work on the engine to justify premium, you just spending extra for no gain.. If an engine is optimised for super and you paying extra for premium without further mods, you will receive 0 benefit at all
Up in the US, premium fuels come with extra additives to clean the engine etc (eg. Shell V-Power, Chevron Techron etc) but here, its just the extra 3 octane you paying the money for..
Try both back to back, see if you feel a difference, good to go! Unlikely a car will knock on super anyway because of anti-knock sensors
