			I remember the reports of the MTBE making people(gas attendants) sick from the fumes.  Kind of ironic that adding liquid oxygen(loose translation) results in apparent lower gas mileage.  Obviously, the colder air adds to the lower mileage due to longer warmups, lower tire pressure, etc.  It's kind of like saying that the 10 gallons of gas you got is really 9 gallons of gas and 1 gallon of oxygen.
