The EPA has now proposed that all gas contain 15%. They want the subsidies for ethanol to be expanded. Along the way they are going to shorten the life of all the engines we use. Progress? Stupidity??
When ethanol content gets about 10% it apparently can damage engines. Car and engine makers are challenging the proposal saying “E-15 has been shown to adversely affect engines.”
However, agribusiness profits mightily from ethanol, doesn’t it?
