I agree with your statement that the price difference is not worth the switch for mileage gains; however, (excuse my ignorance) does not premium fuel offer any other benefits in maintaining the overall condition of the engine? Otherwise, does Premium fuel contain any other agents that regular lacks that keeps the engine running cleaner and efficient over time?

ps. Thanks for posting, I was wondering if there was much of a difference. I usually alternate ie. 91,89,87,91,89,87, etc. etc.
