I doubt you can make ethanol at home that can be legally used as fuel for your car.
Ohio Revised Code Section 5747.77 defines "Ethanol" as "fermentation ethyl alcohol derived from agricultural products, including potatoes, cereal, grains, cheese whey, and sugar beets; forest products; or other renewable resources, including residue and waste generated from the production, processing, and marketing of agricultural products, forest products, and other renewable resources that meet all of the specifications in the American society for testing and materials (ASTM) specification D 4806-88 and is denatured as specified in Parts 20 and 21 of Title 27 of the Code of Federal Regulations."
I don't know the specifics of "(ASTM) specification D 4806-88" or "is denatured as specified in Parts 20 and 21 of Title 27 of the Code of Federal Regulations," but I would bet these references do not permit at-home stills.
You may want to consult with a chemist or other professional about this.
