EU ratings are 95/98, which are equivalent to US ratings of 91/93. So, EU 95 octane = US 91 octane and EU 98 octane = US 93 octane. Top performance with EU 98 octane = 93 US octane. Small loss in performance with EU 95 octane = 91 US octane

there is no benefit of pushing the ignition advance further up (no torque to be gained). the engine is not knock limited. ofc you can hit knock with low quality fuel. or if you advance the ignition you will be riding on the "knock retard" table ie less advance than originally. make sure you run high quality fuel (fresh) ay etanol based (e5 and e10) lose their octanes within a month
