I couldn't find the old Ethanol blending thread. Previous tank was Gasohol with upto 10% ethanol, 27.73MPG. I ran a tank of ~15% ethanol, MPG plummeted to 21.28 MPG. I didn't drive most of it so I don't know the conditions but the Ultragauge said it would be 29MPG. :/

Latest tank was E20, 28.1MPG. Ultragauge said 32.0MPG. :| Not very scientific but I'm more concerned with drivability at this point. It's running good, nothing aberrant.
