[Shotimes] Cold Weather MPG

[Paul Nimz]

I agree, I get about 2-3 mpg less with the boozefuel.  Which puts it right
around 10%.  It is ironic that they advertise the ethanol blend as Cleaner
air for Illinois when in fact you are using more fuel and pumping that much
more CO2 into the atmosphere....
