Right now, in my area, at the fuel stations where i buy from, E15 is $0.50/gallon less than E10. In fact, last time I filled up, I looked and E15 and E85 was the same price. I thought that was unusual, which I think it is.

To respond to the OP, the technology is there to have ALL vehicles set to allow E85. I don't know why they wouldn't make the vehicles that way.  Consumers should be able to choose whether they fill up with E10 or E85. Build the vehicles so consumer have that choice.  That is my position.
