Help with MS Encarta Encyclopedia - Ethanol?

[Greg Koehler (Volt Computer) <a-gregk@microsoft.com>]

This is non-quattro, but I thought someone out there might be able to 
help me with my job.  One of my fellow editors on the encyclopedia is 
working on automobile racing articles and is wondering what "ethanol" 
gasoline is?  Is this just regular gasoline? Unleaded?  I've heard of 
the word before, and methanol as well (which I believe uses methane), 
but I've never bothered to figure out what it actually is.  If someone 
gives me a good explanation, I can make a case to include an article on 
Audi in the next version of the CD-ROM (fat chance).  Any help is much 
appreciated.
