If it works you might see a 10-20 mile improvement in mileage per tank.

I sincerely feel a 25 mile test is not going to tell you anything , 0 , even if a graduated glass tube was used to measure there is not enough time for the effect to have effect.

I would expect you could gain about a 1/2 mpg ,reportedly my beetle with a roof spoiler is factory tested to improve the mileage by 1 mpg.

I may have confused things, I tried testing my air dam, which I have used for several months, but having removed my power steering, I wish that I had A-B-A tested just removing the belt. I just thought that it would be interesting to simultaneously test two variables, one per car, but it would be far simpler to involve her in my life as little as possible.

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?
According to published SAE research,an automobile requires 22-miles of driving at 50 mph to bring all components/fluids up to equilibrium temperature.If road testing is attempted before achieving this equilibrium temp,you'll never be able to sort out what did what from your results.

I found my car seems to mysteriously and indefinitely gain .1mpg or .3% every 4-5 miles I go even after the initial 15miles or so of warm up. I've wondered if it might be from increased rake as the fuel tank gets lighter. Whatever the reason it makes it so I don't think I could pick out results that have an impact of less than about 1% on the vehicle
