My reliable sources tell me that for driving a flexfuel Ford Taurus that there is no difference in cost between driving on E-85 and regular 87 octane. I think that is because the engine has been optimized for driving at higher octane than 87, and of course, ethanol boosts octane rating.

Were any mtbe needed to boost the gasoline to 87, or is ethanol added to the blend of all grades, is ethanol in 87. Robert seemed to be surprised that 87 was the standard octane in many states. I have never seen 85, except maybe in Denver, I don't think I saw it in LA.

What is the octane rating from the refined "gasoline" and where do they start adding ethanol to up the octane.

In Minnesota ethanol at 10% is added to all grades of gasoline with few exceptions. You can get pure gasoline with no ethanol in it, but in the seven county Metro area you have to pay hyper premium prices to get it at very very few gas stations.
