Reading the general forum i saw the american 300c's have a recommended 87 octane fuel from chrysler. How does this translate to us in australia, as far as i know our fuel only comes in 91, 95 and 98 octane unleaded. Do they use a different system of rating their fuel over in the states or do they in general just have inferior fuel to us? What octane fuel should we be using in our 300c's over here? And any idea what rating we should be expected to use in the srt8's???
