I don't have any stats on E85 but have been using it for years--when I had an e90 and now with my f30.

I use it usually three weeks of the month and my routine is 4.5 gal e85 and the rest 91. For the sake of comparison, I have used straight 100 octane as well as a blend of 100, e85 and 91 but found my usual blend to be the same as far as how the car runs.

Everything I have to say is subjective, but the car not only is faster with e85 but seems to run better. The cat-less dp smell is less. One curious thing that could be my imagination, but happens most of the time is that the car seems to be particularly fast and peppy once I get down to a 1/4 tank and this is not because of weight reduction as I don't feel that with just straight 91.

So, I would be a strong proponent of e85 usage for jb4 users with FF wires.
