So none of you had boiling gasoline problems before there was ethanol? The volatility of the fuel is not that much different with ethanol as refiners adjust the base fuel before adding ethanol. Many areas are transitioning from winter fuel to summer fuel right now. If you happen to buy winter fuel and get into a warmer day or drive a vehicle that has a really hot engine, you are going to be exposed to gasoline boiling over in your carb or vapor lock. These problems will be less of an issue in the summer as the EPA requires all retail sites to be converted to summer gasoline by June 1. I don't mean to defend ethanol, but not sure it is a big part of the boiling gasoline.
