in my spectra5 I typically get about 27 mpg... and my wife gets about
25 mpg in her EX...

we commute about 155 miles a day (roundtrip)... and the past couple of
weeks we've been driving her car... it has 10k miles, and mine has
over 20k.

anyway, I've noticed something odd about the EX's MPG...

if I run the gas down to almost empty and fill up, it's about 25
MPG... if I fill up at about half a tank, I'm getting 29-32 MPG...

actually my wife noticed that... I thought it was just my superior
driving skills.

anyway, the only thing that makes sense is evaporation... like they
say, numbers don't lie, MILES/Gallons= MPG...

oh, and this is in the Texas Hill Country/Highland Lakes/Austin area,
so it gets a little hot here... but really it hasn't been THAT hot
until this week...  it cooled off today, the high was just 99 in
Austin. but it seems consistent all year... it's not quite 1 year
since we bought them.
