If you guys went into E85 expecting great power gains for cheap fuel, you did it right. If you went in also
expecting fuel economy, you did it wrong.
Lots of info on this in other threads but usually I think the expectation is somewhere around 20% worse fuel economy. Ethanol has less energy density than gasoline.
That being said, please keep posting your experience, I want to see how far off "breaking even" E85 is (given that it is cheaper than premium). I have been considering it myself given how abuntant E85 is in Nebraska
