 If this dry fuel puts out zero and then fuel with additives put out 10, what did the original fuel with the sulfur put out? There's so many politics involved in that. It's like these trucks when you put the death on them. All right, this truck got this many miles per gallon or burned this many gallons of diesel over this many thousands of miles. If we put the diesel exhaust fluid in it and choke it down with emissions, now we've reduced, let's say we've reduced our fuel economy by 25%.
