In France they convert surplus wine into ethanol for use in biofuels. In Australia many petrol stations sell E10 fuel, petrol with up to 10% ethanol content.
Our Mazda 626 requires either premium unleaded or E10 fuel, and this must be the case with many of the more expensive European vehicles. It has just occurred to me that there might be a business opportunity here in selling premium E10 containing ethanol sourced from wines of a good vintage. Can you imagine running your Renault or Peugot on E10 sourced from wheat? Surely it would run smoother on a good French wine? Or your Mercedes on a fine German Moselle. Even your Fiat’s fuel economy would improve with a fuel from Italian grapes.
Oh, and while your at it, would you like to purchase some tablets that improve your car’s fuel efficiency?
