Does anyone know of an easy & cheap way to dermine about how much ethanol there is in fuel? Around here it's supposed to be 10%, but has varied up to 50%.

Briggs & Stratton part number 10023, alcohol percentage tester, should be under $10. This site has it for less than $5. It's a calibrated test tube: Put gasoline up to the fuel mark, add water to the water mark, cap, shake, let it settle for a few minutes, and directly read the alcohol percentage.

Too many people who were born on third base actually believe they've hit a triple.

Thanks- it's rather obvious when you think to use water to extract the ethanol. I'll let you know how well it works.
