Yeah depending how you drive and where and how much!!! I would never except in case of emergency! Put reg -gas is a premium recommended car! Besides the knock damage why? You WILL GET BETTER GAS MILEAGE with premium and the 10% or less difference will be $0 in cost except for engine damage and warranty!
