You only need 87 octane. Higher octane fuel is for use when combustion chamber pressures are higher like when you add A supercharger. Octane is not A performance additive, rather it raises the fuels resistance to burn to prevent preignition in higher compression motors. If you use low octane fuel in A higher compression motor the fuel will ignite prior to the sparkplug firing causing pre-ignition/detonation from the pressure in the cylinder. No advantage to using A high octane fuel in A low compression motor.
