I drove the car about 20 miles before any testing so it was completely warmed up. A is with the dam and B is without. I reset the scangage at a set point after getting up to speed and set the cruise control at 60 to be consistent, drove 5 miles one way, turned around in a parking lot and returned to set point on all three runs. Temps were the same on all three runs with a stop of maybe 5 min. between runs to take off dam and to reinstall it. On the last run I actually had to pass a car but I didn't need to touch the throttle, I don't think it should have made much difference. A=46.1 mpg, B=44.2 mpg and A=45.6 mpg. Chumly
