Hello I will help,

You can run it til it is half way empty then fill with premium and run it empty then fill as normal. The computer and knock sensors will compensate for the lower octane and you may feel reduced power, the check engine light might come on but it will all clear once you get back on the high octane. Try to avoid towing if you do that until you get it filled with the premium.

Please let me know if you have further questions, if nothing further please complete the rating

Thanks
