Here's a more logical effort. Email your congressional reps and ask them to support this that I got from my Representative...
H.R. 2493. "This bill takes aim at the proliferation of specialized "boutique" fuels to prevent further fragmentation of America's gasoline supply. This bill aims to reduce our fuel blends to a small, manageable number of blends so that gasoline supplies are much more stable. Unfortunately, my legislation has experienced opposition from the oil industry and oil state legislators."
I know my ST runs better on real gas without the 10% shot of ethonol, but we need to get rid of the various formulations and have one or two for the whole country.
