I haven't done any scientific tests like yours but I know I was getting 34-37 in the morning to work. It is about 3.8 miles, same route, about the same traffic. The first morning I used it I hit 62.3 according to Guino. The same mileage I could get on the way home when it is warmer out.

A cold engine kills me driving to work, too short of a drive. But a short drive to work is nice just not for FE.

Thanks Darin, those graphs were the reason I went with the one I did. I read every single word on those tests you did and tank sounded like best choice.
