I just run the 93 octane. The cost difference is minimal and honestly, I hate spending more time than necessary at the pumps anyway, between the lady with the cell phone on one side and the guy with the cigar on the other...

No kidding, I watched a dude with a smoke hanging from his mouth plop his plastic gas can on the tailgate of his truck and proceed to fill it one day.
I felt like asking him to give me a minute to drive away before he blows himself up. Instead, I informed the attendant, who gave me a blank stare, as if I had horns coming out of my head and had asked directions to the local baptist church.
I got in my car and drove the hell away from there, and haven't returned.
