Can cars run on shine (Aka corn whisky/ethanol)?

I'm 15 years old and will have to start paying for my own car in a few months, including the fuel. I live in the South and know a little bit about making shine and how it works abd all. I know cars can run on mixed ethanol (corn whisky) and gasoline, but will it damage my car and what are the risks? Also, what percentage is a safe mix? My daddy abd grandaddy have fields abd fields of corn, so obtaining the mash would be no problem... Just saying. Anyways, if you know anything about ethanol (shine) as fuel, please leave suggestions or any feedback.
