    Snow and average temperatures in the 30's have been a bitter reality throughout the month of March here in Minnesota... until this week. We are suppose to see daytime temperatures in the 50's finally. Yeah!

    1,184 miles so far this month. And despite the far from ideal conditions, only 24.9 gallons were used. That calculates to 47.5 MPG.

    I can't wait to see what this warm weather brings.

    I've only filled once so far this month, early on, so it was more like Feb. mileage. I'm on my 3rd consecutive tank that should be over the 50mpg mark!!! Right now, with about 350 miles on the trip odo, I'm showing 51.7mpg!! And that's after a couple little cold spells (30s & 40s--not cold spells ala John1701a). The days in the 70s are the ones that give ME goosebumps--I improved my mileage over 1 full mpg over a 25 mile round trip (both from cold starts) 200 miles into the tank one day. I just know I'm going to be pushing the 55mpg mark come spring/summer--at least until I have to use the A/C again.

    I'll post all my March numbers at the end of the month...Danny, I'm actually not quite sure what this thread is intended for. Tank by tank data entry, monthly data, last months data? IOW, it would seem more useful to me to, on the first day of the month, to post a sticky like this that asks for the prior months mileage data.....

    For example:
    On April 1st make a sticky post:
    "Post your March Mileage Data Here"
    followed by
    Total Miles:
    Region/location:
    Est. Daily temp:
    Calculated MPG for March:

    Then folks could go back and look at monthly archives and see what others historically got for the entire month based on temps and regional variations.

    If your intent was otherwise, I apologize, I just don't understand it exactly.

    I think for some people it'll be easier to come in and post it as they go through each tank instead of having to keep track throughout the month. I really don't care how it's done, and I think that we should do it however it would be best for everyone.

    If that way is best, that's fine. Or we could include a monthly round-up included on the first tank of gas for the next month (ie put March's overall #s with the data for the first tank of gas in April).

    Whatever works best for the group.

    > (30s & 40s--not cold spells ala John1701a).

    Actually, the average was LOW 30's.

    There were a few days with temps in the teens. And on one commute, it was only 10F. Eek!

    The weather is getting warmer, and my Prius is getting better mileage. This shot was taken after a highway trip...

    Had our first 70 degree day yesterday here in the Chicago area, and the improvement in mpg was huge. My last full tank stats were
    tank miles: 420
    display mpg: 49.8
    avg temp: 45.2 F
    lifetime miles: 1088
    lifetime mpg: 45.2

    Here's yesterday's screen:

    I'm down to 1 bar again and 538 miles. I think that I'll wait this time until it starts blinking!

    First March Fill Up--3/12/04
    Tank miles:438
    Overall Miles:4909
    Avg Tank Mileage:47.4 calc./50.4 shown
    Avg Overall Mileage:45.0
    Avg Temperature: ~40F

    Second March Fill Up--3/26/04
    Tank miles:439
    Overall Miles:5348
    Avg Tank Mileage:51.1 calc./52.0 shown
    Avg Overall Mileage:45.4
    Avg Temperature: low 50s I'd guess

    I've been driving without the use of A/C for the past 3 (now on 4th) tanks, and it's made a dramatic improvement in MPG, as has the warm weather.

    Tires at 42/40.

    Currently 75 miles into my last fill, no lost bars on the fuel guage showing 56mpg!! Let's hope the temps stay in the mid-60s+.

    Trip from the dealer in Moses Lake back home to Vancouver WA. Mostly freeway driving:

    Tank miles: 297
    Overall Miles: 447
    Avg Tank Mileage: 40.8 mpg
    Avg Overall Mileage: 44
    Avg Temperature: 55

    I've only filled up once so far, and I was a bit cautious after all the posts about short fills and air bladders, but I didn't have any problems, just filled it slowly.
    I had 3 of 10 bars showing before the fill, and it took almost 8 gallons. $13.50 to fill up at $1.699 per gallon here in Vancouver, WA!

    So, is there a life-to-date MPG hidden in the Prius' computer somewhere? Or do you have to log gallons the old-fashioned way with a log book?

    I know I don't have a prius but I should be a poster boy as to why everyone should own one

    My non prius car got this at last fill up

    305.6 mi/13.136 gal

    23.6 mi/gal

    This is the best milage my non prius has ever gotten, that 1000 dollars I put in it may have helped

    Avg Overall Mileage 44.8
    Avg Temp 65 with a heat wave of 80 for three days

    An observation ... as the temperatures increased during our little heatwave, I noticed those days netted much better mileage - about 1% per 2 degrees. (So when it went from 65 degrees in the evening to 85, my mileage went from 44 to a little over 48 for the exact same drive.)

    I guess the colder weather, short trips, and hills and dales I traverse on my daily rounds means lower fuel economy than advertised.
