I have recorded the pump MPG and the readout MPG for the last 35 fillups of my
2005. Averaging these values shows the displayed MPG to be about 1.25 mpg
higher than the MPG from the pump calculations. This difference has recently
come down a little bit, having run about 1.5 during the colder months.
My fillup end point has not been very consistent. The true calculated MPG has
differed from the Prius display value by as much as 6 mpg, but it is generally
much closer. The averaging should minimize this variability.
I have moderated my driving and the last 4 tanks have displayed over 55 mpg on
the screen. I doubt that the next fillup will achieve that goal.

In what way did you moderate your driving?

Most of the difference has been moving from cruising the left lane to
following the pack in the rightmost lane. ;-)

Today I drove about 160 miles, much of it at 70-80 mph with the AC on. My mpg
dropped to about 50.
