Sorry for the confusion if it came across as sounding like octane alone.

Also it seems you have never tested a full tank of higher octane fuels in your car which I have many times recording mileage as well and "yes" it does give you more mileage than the regular 87 fuel but not enough to justify the difference in cost. 91 fuels contains no ethanol thus the reason for extra miles and the reason why flex fuels give you less mileage....pretty simple to understand. Next time you should do your own personal tests first then give your comments on the matter! Thanks
ROFL. Dude, you are all over the place. First paragraph you say read again and say not just octane. Then you say higher octane fuel gives better mileage. Then you say it is because there is no ethanol. BTW many of the US states sell only E-10 no matter what the grade, so more misinformation.

I don't know where you get your information from other than your "personal tests" but you put it out there that higher octane equals better mileage and that simply is not true. You don't have to take my word on it, like I said, Google it.
