Between Mexico and the U.S.A we feed the World with Grains... the signs on the pumps say up to 10 % --- at 10 % for 10 trucks of fuel 1 is Ethanol.... Take .02 % from 100 Trucks and only TWO TRUCKs... A drop in the bucket, but every drop counts for making Diesel. The Refinery's add chemicals to get the Octane correct. Alcohol only reduces the Carbon Footprint. My Grandmother always had a small Can of Coal Oil -- when you stepped on a nail or cut from glass, she put Coal oil on the Wound to prevent Tetnius. also called Lock Jaw. Coal Oil would not burn the Skin but Kerosene would.. everyone had Coal Oil Lamps then the name was changed to Kerosene Lamps. For the last 50 Years you could not get one drop of Coal Oil. What would the World Be without Pop Corn or Grits !!!!
