Premium gasoline is better for a performance engine and even MPG. It's not that much more expensive, like <$3 dollars per tank(13 gallons). Don't be penny smart, pound foolish about it.

premium gas is not more efficient or more safe. If the engine is designed and tuned to run safely on regular unleaded then there is no reason not to do so unless you're absolutely desperate for that 10 extra hp. It's all conjecture anyway. Nobody knows yet what the recommendation is going ot be in the owner's manual.
