This is my exact experience with the 07-08 Fit, yes.

Different drivers, but my SO is regularly getting 45-49mpg in her 07 manual Fit, whereas my brother averages just about EPA in his 08 automatic - low 30's. The auto has much better top gearing than the manual, so it's not intuitive to me why this is.

Here's my guess: the auto seems to hold onto gears much longer - she shifts somewhere around 1500-2000rpm - and I expect the torque converter isn't locked up all the much in the auto.
