Just ad a bottle of "octane 104" that should take care of the problem.

After you add the 104 you don't have to run it all the down, just fill it as you normally would, the treated fuel will mix nicely.

As long as you had premium still in the tank you should not see much of a change engine wise, but keep in mind if the car is run on straight regular gas it will gum up your system with carbon deposts so do a tune up once your back on straight premium, shouldn't need to do more then clean the maf, thortal body heat sensor, and clean the plugs.
