Yeah, stratification is a much better word here,  but if it was a 
problem, wouldn't it be MUCH more of a problem in the underground 
storage tanks, where it's likely to sit for much longer times? Maybe 
they have stirrers in those tanks now, but I doubt it. A moving 
vehicle should be much more likely to keep the fluids mixed than a 
stationary tank.

According to an article in Physics Today a few years ago, it would 
take ALL the corn raised in the entire US to make enough ethanol to 
convert all our (US) gasoline to 10% ethanol. This option is being 
sold as a way out of our current dilemma/addiction, but it's not.
