RE: E85 Fuel on 3.5 V-6
The FFV motors have a sensor in the fuel tank which constantly monitor the ethanol content of the fuel. this sensor then adjusts PCM calibrations to work with the blend concentrations. You should not see any drop in fuel economy. Also, when adding E85 into a tank of normal fuel. you should drive the car for aprox. 7 miles before shut down. this will allow the new calibrations to be perfected by the PCM. Failure to do this may result in a check engine light.
Also... it has 0 negative impact on fuel injectors and other components. they are all designed to work with E85 seamlessly.

A Chevrolet Technical Bulletin on E85 fuel (Document 1572801) says: "E85 has less energy per gallon than gasoline, so you will need to refill your fuel tank more often when using E85 than when you are using gasoline." You will see a drop in fuel economy when using E85.

The following is from a paper I had to write for school:
"Another drawback is the fact that E85 has the energy equivalent of 80,000 BTU, while gasoline has the equivalent of 125,000 BTU. This means you must have 1 ½ gallons of E85 to equal 1 gallon of gas, thus getting worse gas mileage than gas does. However, E85 does produce more horsepower compared to an equal amount of gasoline."
