Wow. No shyte. With all of the variations in a commute over a tank of gas, you can measure a 1 mpg difference? Dude...
In a Focus, a 1mpg gallon difference is completely unnoticeable....whether it be at the pump, in the wallet or on the road. That's only 12-14 miles per tank. I can do that simply by changing shift points....as can anyone else driving a manual.
