First hint that they have NO idea what they're talking about is that they claim 10 gallons of gas is 1280 ounces. Bzzztt! Water's around 8 pounds per gallon but gasoline is about 6 pounds and even diesel is only about 6.75 pounds. Anyway, if there was a magic additive that increased fuel economy by 35%, it would be in use already. Their theory of "breaks the surface tension" is hysterical to anyone that understands how fuel really atomizes, but by all means anyone that wants to try this out, be my guest.
