Reason for 91 in Cali. altitude.

You DO NOT NEED anything higher than 91 octane. The cost and use is a waste and you WILL NOT see any performance improvement.
It's got a cop motor, a 440 cubic inch plant, it's got cop tires, cop suspension, cop shocks. It's a model made before catalytic converters so it'll run good on regular gas. What do you say, is it the new Bluesmobile or what?
