Okay, let me tweet this a bit. If you could have your jeep that you have now, with a 100 mpg, without changing the amount that a gallon would describe, would you want this to happen, in the future I had to put that in ther, cause when their customers demand same jeep, with 100mpg, they may try to lobby, to get the gallon to be changed to like 7or8 gallons, but called one gallon... if they could burn the fumes from the gas, safely to get to 100 miles a gallon, your all in right, without changing your vehicle physically.
