I drive an '05 Prius.
Since January, 2005 I have filled the gas tank exactly 316 times,
consuming exactly 2,253.713 gallons of gas, for a total cost of
$,005.11 (please note that I am an engineer, a spread-sheet freak, and
I keep every gas purchase slip ‹ weird!) While I have owned this car, I
have driven exactly 110,898.8 miles.
Take out your calculator and divide: 110,898.8 miles by 2,253.73 gallons.
MPG (long-term average) = 49.21 miles per gallon.
I have not averaged the estimated MPG, but I could easily. I suspect
that it would be greater than the actual, but not by very much -- a few
I could easily add a column to the spreadsheet that computes the percent
difference between the actual and estimated MPG. Maybe I'll do that.

Is that UK or USA gallon?
Over my first few fills my Prius C is using 5.0litres/100km or about
56mpg (UK gallon)
