Will take a few tanks to really be able to tell. My SG isn't callibrated prefectly, but going to leave it alone for now.

I can't tell you why, but my scangauge completely missed the mileage improvement with my thermostat change. It was hard work to keep my tank mileage at 40mpg, and I barely made it when I filled the first time after replacing the stat. And the scangauge was way off, as calculated mileage showed a 6mpg difference.
