RE: Ethanol in Gasoline
Hmm, any organic solvent including raw crude oil out of the ground is partially miseable in water and visa versa. Not sure this is going to be scientific enough to reach in definite conclusions.
MTBE use to be in typical low concentrations.
I have heard they are putting as much as 10% ethanol in our gasoline now (but they never bothered to tell us or reduce the price by 10%)
