Ditch your parasitic drag. While we’ve not dyno’d before and after, we have noticed about a 1mpg improvement from just tossing the factory engine-driven fan. This Ford Taurus fan is only needed on the hottest days or when stopped in traffic. Most of the time while moving the fan isn’t needed to keep the little engine cool. Also, if you have A/C or an automatic those are two big power-sucks there too… even worse than the engine-driven fan. No one likes guys dressed as girls. Get rid of drag and gain some power and mileage.
