With no other change, my Jeep loses 4 MPG going from standard fuel, to E10. Summer or winter. (We have specific pumps out here for "farm" applications.)

My 2.5L Wrangler gets about the same mileage no matter what the temp, (IE sucks)
about 17 mpg combined driving. But will stretch out to low 20's on flat freeway cruise.
Due to the add on off road accessories my engine runs warmer most of the time.

Just anecdotal data to toss on the fire...
