I got my new '95 in November. I knew my mileage was not what others are
getting, but last night I actually figured it out and 34.18 is what I got on
my last tank. It's NOT broken in, it's at a little over 1,700 miles. And I
uderstand that mileage on these cars is lower in winter. And the bulk of
this last tanks driving was from short trips around town, probably around 10
miles or so average. My question, should I take it in to see if the
emergency brake is too tight? Did anybody else experience mileage like this
when your cars were relatively new? TIA

A bit more info. The 34.18 mpg was calculated the old fashioned way, x miles
from the odometer divided by y gallons it took to fill it. Also while I was
getting this mileage my fuel consumption screen was saying I was averaging
about 45 mpg.

Don't ever draw conclusions about your Prius mileage based on any one
fill up.  Because of the bladder-type gas tank, you never know just how
close to full it's actually getting, and you need to calculate the
average over several tankfuls to really know how you're doing.

There's nothing wrong with your car.  Your true MPG was 45.  You can't
trust calculating MPGs by hand because the flexible fuel bladder means
that [gallons put in at last fill] do not necessarily equal [gallons
burned since the previous fill].   On this last fill you put in, say, 10
gallons, but between fillups you actually burned 7.5 or so.

My worst tank ever was 44 mpg.  Where I live, MN, the cold weather and short
trips do consume extra fuel but you have me beat by 10 mpg!  I have a self
imposed 55 mph speed limit.  Is this the difference?  At 75 my Prius gulps
gas.
