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.

In 2005 there was a large spill... leaking tank in a gas station chain, where MTBE contaminated local “Spring Creek”... It took over a year to clean up.

Yes, you are correct... a mandate was passed for requirement in minimum amounts of Ethanol during the Bush watch. I know there is a push to up the amount to 20% blend. My question is... doesn’t a vehicle have to be re-fitted to run this concentration?

Cheers...
