Car guys. How important or necessary is it to use high octane gas in a Lexus IS
250? Would it hurt to use 85 octane (in Utah) gas?

Next question, why is it that such cars (Lexus, BMW, Infinity, etc.) require high octane gas? I have to wonder if it adds to the mystique of these cars and really nothing else.
