So that is why I'm trying out a whole tank. But I'm wondering how I have 390 miles with about 57% of my tank still left? I do not know if it is a myth that the bottom half of the tank goes faster than the top half. If it goes about the same then I am looking to get a little over 830 miles on a 13.2 tank. Which is like 63MPG???? Is this realilistic???

I don't think the dials on the console are linear. I do think that you should apply the "GasSavers" rule in the sense that you should have 90 days of gaslogs before you come to a conclusion. That will give you a good way to compare to other GasSavers.
Don't forget that he has more energy content in his diesel fuel, so he should have a handicap

Assuming the above holds true :
38.6 / 34.2 = 1.128 => 113% => Diesel has 13% more energy content than gas. Other diesel owners can chime in on this and correct me of I am wrong. If you apply a handicap, there also has to be a correction for emissions.
Anyway, 52 MPG in a 2006 Corolla? WOW. Have you described your commute and strategies in other threads yet?
