FE Turnaround: Disappointment to Satisfaction, 2010 Yaris. Almost +50 MPH. Thank You! - Toyota Yaris Forums

My understanding is that the MTBE ban is a state thing also, but is widespread enough that the U.S. fuel producers have dropped it altogether. I may be wrong. The knock against it is that it smells and tastes terrible at extremely low concentrations in water, and because of leaking tanks contaminating groundwater and boaters spilling gas in lakes and rivers, it was affecting municipal water supply quality.

The Federal government did pass a mandate (pushed by George W. Bush) for using ethanol that requires the sale of minimum quantities of it, supposedly to replace imported oil with "renewable alternative fuels," and the amount they have to sell now is hard to get rid of when they're limited to a 10% blend. That's the reason for the push to license E15 or E20, and why some folks who test what they get at the pump report finding ethanol levels approaching 20% already.
