Has anyone used E85 for more towing power?
My F150 5.4 is a flex fuel vehicle and I have used E85 fuel in it. There was a noticeable decrease in flue mileage and probably an increase in HP and torque. All the reports state this Ford V8 will ma...

Due to the high octane rating of E85, you can run greater compression, heat and ignition advance without predetonation resulting in better engine performance. Because the energy contained in E85 is less than pure gasoline or E10, it will get worse mileage (efficiency).
A friend recently built a race engine tuned for E85 and has found fuel consumption to be 50% higher than stock tune with aviation gasoline. Part of the additional consumption was due to the extra power he was able to get out of the engine with the higher octane but most of it was due to the reduced energy content in E85. He had to increase his fuel tank size due the reduced range (the original foam lined fuel cell was not compatible with E85 and had to be replaced anyway).
