Why would you use 91 octane? As RyansQuick6 mentioned, nothing is gained by using 91 octane fuel when your vehicle runs on 87. It does, however, cost more... that's not a benefit.I started with 87 regular and now use 91.
Hmmm, my Honda dealer actually told me to use the premium 93 octane gas.
I know that is wrong...
I don't think it was a particularly bad batch of gas, because it does it in the 2004 accord everytime I run 89. However, it could be the BP gas I buy. I always buy gas at the same BP station on my way to work. Next time, I'll try 89 from the Exxon accross the street.I run PetroCan 87 octane with no issues. I was considering Shell since it didn't have any ethanol added but now I'm told that it does, so I'll continue with PetroCan and collect the points.
Melchor, I wonder if that clatter was due to a bad batch of gas?
Like the 'masked man' I wanted a car that runs on Regular gas.
