Harvey,
The best California premium is 91 octane, and I know our high comp engines need more octane than that.
e85 is 15% gasoline, but those using e85 said a couple gallons of gasoline per tank helps the cold weather starting.
Another reason to use e85 may be to pass smog tests. As the cats age, it becomes increasingly difficult to pass the tests in the strict states.
Can't buy it publicly in Northern California, not yet.

The really only advantages of Alcohol is its ability to run very high compression ratios. I mean like 14/15:1. This is where the power comes from, not the fuel itself. To run it on a low ratio will achieve nothing compared to the problems it will cause.
The benefits that can be obtained by using it in a blown car, can be had by using water injection, or fogging Alcohol into the manifold, when boost starts. The rest of the time you have the easy start, no corrosion, good mileage of petrol. 
Now tell me I have missed the point, because I am set in my ways like Beav.  and can't accept something new.
