[6pack] Ethanol gasoline blends

[Shawn J. Loseke]

The ethanol blends do 'go bad' much quicker than older fuels without it. So 
storage can be a problem. All of our fuel in Northern Colorado is 10% ethanol 
year round. Your car should run fine on it. However, if you begin having vapor 
lock problems, you can thank that 10% blend.
