aero mods and mpg

On my CRX, there was a natural variability of between 36-mpg, and 82-mpg, depending on 'routes' and 'weather', and this was without any changes to the car after modifying.

Just shooting from the hip, even if you completely blocked off the radiator, it's unlikely that you'd realize anything beyond a 3.5% mpg improvement. That would be at a steady 70-mph.
