No wonder gasoline in South Florida is about $0.25/gallon more than the rest of the state.
Not necessarily. It just means it's cheaper to make the gasoline without ethanol. If ethanol is required it will make the base gasoline more costly to produce in order to meet the RVP requirements. El Paso, Texas requires 7.0 RVP gas with ethanol.
Unfortunately if you live in Florida all of your gasoline will be diluted with ethanol by 12/31/2010.
