Regarding the mileage question:
I'm no engineer, but it seems like you'd naturally get worse mileage when 
ambient temperatures are significantly lower, MBTE or no MBTE (in winter, 
especially).  I would think that because colder air is denser, it would 
require more gas for the right fuel/air mix.  Since the volume of the 
cylinders aren't changing, your engine would therefore need to use more gas 
per combustion cycle hence lower overall mileage.

Am I on track here?  Any combustion engineers out there?
