If you cant buy 98 then I wouldnt be trying to gain much from the engine . If you decide to run 95 + octane boost be prepared to change plugs more often . If you need 98 use toulene to suppress pinging and run 95

no point . Late cars you cant change ignition timing to benefit from extra octane , stick to 98
