"Hello to everyone,
I was looking into brewing alcohol as a fuel supplement and read that you can operate a vehicle with fruit juices fermented and distilled

Also I was pleased to see that Prince Charles has a Aston Martin that runs on wine that he recieved for his 16th birthday.

I wanted to used the least expensive source of juice available and wanted to know if any other members have tried this method?

Can I achive a higher % of alcohol with grain basewd mash or a fruit dirived mash?

Any help would be appreciated."

"Although fossil fuels have become the dominant energy resource for the modern world, alcohol has been used as a fuel throughout history. The first four aliphatic alcohols are of interest as fuels because they can be synthesized biologically, and they have characteristics which allow them to be used in current engines. One advantage shared by all four alcohols is octane rating. Biobutanol has the advantage that its energy density is closer to gasoline than the other alcohols (while still retaining over 25% higher octane rating) - however, these advantages are outweighed by disadvantages (compared to ethanol and methanol) concerning production, for instance. Generally speaking, the chemical formula for alcohol fuel is CnH2n+1OH. The larger n is, the higher the energy density.

Alcohol fuels are usually of biological rather than petroleum sources. When obtained from biological sources, they are known as bioalcohols (e.g. bioethanol). It is important to note that there is no chemical difference between biologically produced alcohols and those obtained from other sources. However, ethanol that is derived from petroleum should not be considered safe for consumption as this alcohol contains about 5% methanol and may cause blindness or death. This mixture may also not be purified by simple distillation, as it forms an azeotropic mixture.

Bioalcohols are still in developmental and research stages. Use of optimized crops with higher yields of energy, elimination of pesticides and fertilizers based on petroleum, and a more rigorous accounting process will help improve the feasibility of bioalcohols as fuels."
