    Another %&#$%*@% Octane Question!

    why just kidding?? I have 20 K miles on my 2007 CX7. 15 K has been with 85/87 octane and it flys. I will never put 91 in my CX-7 again. It runs like crap, hesitates and lags with 91 octane. That's my experience with my vehicle, and I don't care what you put in your vehicle.
