You have to adjust your ignition timing to take advantage of the slower
burning higher octane premium. The advanced timing may give you a bit
more pep and probably will give slightly better throttle response. It
will raise your idle speed so you will have to readjust that too. It may
give you very slightly better mileage, or it might not.

There is a station planned for Eugene OR that will sell alternative
fuels including biodiesel and alcohol blends. We may yet see E85 on the
west coast. Since I live right here in the Eugene metro area, I am
keeping my fingers crossed.
