Grill Blocks on my Taurus

In a recent post I explained in simple terms how I jumped from 17mpg to up to 23mpg. In the quest for even better mileage, I put grill blockers on my 1998 Taurus. For the upper grill I just used clear packing tape, and for the lower grill I used cardboard taped on with the same clear packing tape.



I drove for 300 miles like this (one tank of gas) and it made NO difference. I came to find out that although it does work on many cars with poor aerodynamics, the Ford Taurus that I have as a Cd of .30 which is VERY good to begin with.

I am still contemplating other mods, but I really hate working on car mechanicals so we'll see how far I go.
