I was never really a big believer in the differenece in grades of gas until this last fill up. Keep in mind, I have used 91 since I got my car but about 3 months ago, I started using Chevron or Shell exclusively.
Anyway, I was not able to go to my normal Chevron station, so I had to fill up at a Circle K. I still filled up with 91 octance, but I have to say the difference in how my car runs with Chevron to what is in there now is night and day. My car runs a bit rougher, idles a bit rougher and just doesn't feel the same.
I can say this, I will only use Chevron or Shell gas from now on, even if I have to fill up with a half tank remaining.
