Ethanol vs. Your Engine

[emptysea]

Doing some very quick math: i have 17000 miles on my bike over 3 years. Let's say I get 45 mpg. 17000/45=378 gallons used. If I increased my fuel economy by 10%, I would be getting about 50mpg. 17000/50=340 gallons used. A savings of 38 gallons of gas. Let's say that the cost of that gas is $3.00/gallon (I usually pay a bit less than this). That's $114.00 over 3 years or $38.00/year....or a little more than 6/10ths of a cent per mile. I'm just not going to worry about fuel economy in general or how ethanol does or does not affect it specifically.
