My wife and I are having a debate.  She believes that your gas lasts longer 
when your tank is more full (I guess because the needle appears to go down 
slower).  I believe that a vehicle with an emptier gas tank would get better 
gas mileage since you're moving less weight.  Is either of us correct?
