Premium gas in a NA C230??
Why would a 1998 normally aspirated C230 require premium gas? I don't consider myself cheap so I don't have a big problem spending the extra cash. I drive a Porsche 944 turbo in which I tweak the power so octane and detonation is understood. I am buying a 98 C230 for my wife. Could it be because it just mught have a higher detergant quality?
