Octane booster is a waste of money so don't even bother. You premium users are really getting the shaft with the Gas Retards recently. I don't really have any advice besides keeping your eyes open for a station. A QT near me got in all three octanes last night and it was a nightmare getting in there to fill up my near-empty Mustang. Things should be back to normal soon, as soon as people quit being dumb. Good luck bro.
