Hi, I've just bought a 2004 Copen 660cc. Does anyone know what the factory fuel recommendations are? The previous owner ran 91 octane in it, but I'm suspecting that it might need 95 or higher octane?
Do you still have 91 octane in New Zealand? Or do you use the american spec that has 87, 91 and 93 octane? In Europe, 91 octane fuel has not been sold for like 10 years. 95 octane is the minimum. You will not get any performance benefits from going to 98 though
