I guess that I did not drive the car enough to warm up, but I did the A- route, almost twenty-two miles, went to fill up, and it clicked after 0.147 gallons, so I decided to do two clicks each time, and it stopped at 0.174 gallons, and I almost had gasoline spilling down the side of my car.
Okay, sure. 150 MPG. Somehow, I think that driving with the air dam would show worse results, and my second A-run might be worse still.
For how long do you need to drive your car before it is warm? It is over a hundred degrees for most of the day; how cold is that?
