An inch of topsoil is created in about one thousand years. Ethonal si manufactured by heating biomass to its boiling point and collection the combustible distilate. That product is mixed with a very efficient fuel and thereby reducing the efficiency of the engine and reduces the working life of the engine and its parts. The manufacturers of my pumps and generators reccommends against the use of ethonal in the motors for these Honda products. Not only does ethonal damage engines it burns topsoil.
I live in Boise, Idaho and have the option of regular (No Ethanol) gas 87 octane. My car runs better, get better mileage and pay just a tad more. If more states allowed this ethanol would be a thing of the past.
