My very unscientific analysis seems to suggest max A/C with the fan at minimum speed didn't help. One day I ran the A/C set to 75 degrees, with the fan at medium speed. The next day, I ran it at max A/C with the fan at minimum speed. Both days, the average was about 54 mpg. Driving conditions were similar. Although it was not a controlled laboratory environment. So... grain of salt.

One note about running max A/C: I had to manually cycle the A/C on and off every few minutes. That was annoying. With the temperature set to 75, I just set it and forget it.
