enlighten me.
It was my understanding that ACN 91 was Arizona, California and Nevada. Oh wait I just answered my own question. In other states, 91 would still be better than ACN 91, which is the worst gas in the nation.
yes i may have used 91 octane loosely. But for OP sake, he was from Arizona. So my intent is still valid.
