National Unleaded Average

To the best of our knowledge, Chrysler does still require a special FFV engine oil. The concern here is that uncombusted ethanol (especially during rich cold start conditions) may migrate past the piston ring resulting in cylinder wall washing which reduces cylinder wall lubrication and could run down into the crankcase, diluting the engine oil.
^Yes, we do.

The “E85 MPG/BTU adjusted price” represents the adjusted E85 cost to regular unleaded gasoline. According to the Energy Information Agency, the average E85 is 94,190 BTU assuming a year-round ethanol content of 74% and regular gasoline averages 124,000 BTU. The adjusted E85 MPG/BTU price reflects how much a consumer would have to pay for E85 gas to receive the same fuel efficiency as regular unleaded gas

I will also state that I have found myself to be partially wrong in one aspect, from the first source I did find this,....
Ethanol has less energy content than gasoline. However, E85 also has a much higher octane (ranging from 96 to 105) than gasoline. FFVs are not optimized to E85, so they experience a 10-15% drop in fuel economy. This will vary based on the way one drives, the air pressure in the tires, and additional driving conditions.
