If you have a stock pulley and its not insanely hot and you dont put your foot into it much you can use 89 or 87, esp if you are going to be doing light throttle highway driving and not kill your car.
Friend of mine ran a bonnie SSEI for quite some time on 87 on long highway drives without a problem. Prob got reduced performance though. If you are modded or like to plant your right foot, its prob not a good idea.
Super just broke the $2 mark here in MD. Its hovering around $2.03-2.05
