I think that federal regulations effectively require ethanol now that
MTBE is not being used. So I don't think you're going to find gas
without ethanol by shopping around.

Since I remember the fuss about MTBE getting into groundwater from
several years ago, I would think pretty much everybody has been using
10% ethanol for a while. But maybe Texas is just getting around to it.
