That seems like a pretty valid number.
Just doing some simple thinking... if an auto gets 24MPG and a gallon of fuel weighs 8 pounds (water weight), then over 24 miles one is going to disappate .3 pounds of something per mile...
Gasoline is lighter than water. Approximately 6 lbs /gal vs. about 7 lbs/gal for methanol.
At any rate, only a small portion of the burned fuel turns into polution, so the figures are fluffed way out of line for that mileage.
