 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%. If we've reduced it by 25%, well, they said, well, we've cleaned up the emissions, but now we're having to put 25% more fuel in it to go the same amount of miles. Right.
