#941 of 997 my early experience with my pre-owned Yaris
Jan 10, 2012 (12:30 pm)
Just aquired my gorgeous 2010 Prius for $15,400 (has 45K on the oh-do). So far, after just 1/2 a tank, my car seems to be averaging only 47mpg according to Prius trip computer )which means I am probably getting just 45 mpg). I just placed more air in the tires and am learning from all of you how to goose more mpg from the beast. Janaury is a horrible time to set the bar for this car, so perhaps with warm weather and a few tankfuls I will see something over 50 mpg. The problem is my city commute is only 8 miles one way, and the car is barely warmed up by the time I get to work or to home. I have started to carefully track my gallons per fill-up and my odometer readings, so I should know in a month what my true MPG is going to be.
On the freeway I easily achieved a mpg over 50 mpg . . .which i find a little odd given the EPA estimates--but I realize athose estimates are based on paritial usage of the EV mode in the city, something that can't be accomplished on the freeway.
Anyway, I am a total computer/mileage geek, and so I am completely in love with the "geek-out" experience offered by the Prius computer readouts and such. It truly is an engineering marvel.
I dont think my tires are low rolling resistance tires . . .they are Westlake SP-06 . . .seem to be a softer tire made more for traction and/or quietness versus low RR. Seet this link and maybe you can comment on them? and recommend another tire? Is the "Michelin Energy Saver A/S" my best best?
Thanks so much.

If you are averaging 45 mpg on an 8 mile commute you are doing great -- really great. The $500 you will spend for new tires won't change much. Wait until you need them.

i agree with jayrider...45mpg on an 8 mile commute in cold weather is really good.
One trick I learned with my '06 Prius in cold weather is to keep the temperature high on the heat setting (about 77 deg) but after the car is warmed up inside to turn the fan to the Off position. This seems to prevent the car from running so much at stop signs and traffic lights, but keeps the warm air "floating" inside the cabin as the car is moving.
Or you can just turn the fan to the OFF position when you come up to a light and then turn the fan back on when you start driving again. Personally I wish the Prius had an "ECO-CLIMATE" control setting that would automatically do this to prevent the engine from running when stopped just to keep the hot air blowing in the cabin.

Sorry folks--when I typed that I am averaging 47 mgp, I should have made clear that this is reflective of ALL my driving to date, not just my 8-mile commute; the average for my 8 mile commute is much lower and is screwing up my overall average. As you all know, the first five minutes in the Prius gets you about 25 mpg. My 8 mile commute is about 15 minutes in length with Atlanta's typical city traffic stop and go.
I brought the car home from the dealer with about 1/2 a tank and averaged 47 mpg on what was left of that first tank, as I reset the trip odometer when I took possession of the car. I then tanked up the gas on Saturday and so far have driven 98 miles . . . and so far my average has dropped to 44.5 mpg . . .my 8-mile commute makes up a fair share of my driving. If i had realized that the first five minutes of running time gouged the MPG this severely, I wouldnt be as disappointed as I am now . . . I would sure like to average 50 mpg and realize the cost savings . . . maybe I should move to the suburbs and do the 45 minutes commute
Anyway, i tend to do longer drives on weekends, and with the 3-day weekend coming up we will see what my MPG turns out to be on my first tankful. In the meantime, thanks to all of you for your suggestions. The fan suggestion is a good one that I hadn't thought of, so thanks much.

On two tanks I only got 43-44 mpg via miles/gals to fill. The TripA CONS display showed 47-48, so about 10% inflated. I'm guessing most Prius reviews are using the inflated value vs actual mileage calculation.
Still pretty happy, but not as astonished as I once was.
#946 of 997 First tank on my "new" (new to me) 2010 Prius; 47.2 computer vs 45.6 actual
Jan 21, 2012 (11:51 am)
OK the verdict is in: I drove 405 miles on my first tank (was down to one bar, but the bar had not begun to blink yet---I was supposedly 40 miles from empty but I know this car has a 2 gallon reserve tank, and for good reason). Anyway it took 8.886 gallons to fill it up. So 405/8.886 = 45.6 mpg. My Trip A display showed 47.2 mpg. I am happy that I got 45 mpg, but gosh I was hoping to be one of those lucky folks who owns a Prius that gets 55plus mpg.
1) dealership where I purchased the car (non-Toyota dealer) did not put synthetic oil in the car, so I intend to do that and perhaps see some increase.
2) the cold weather of late has not helped the mileage. Even Atlanta gets to freezing temps every now and again
3) I'd like to hyperinflante the tires and see what happens.
Time will tell. But I know the single biggest factor in my own mpg are themany short trips I take (very short work commute, etc).
#947 of 997 After 3 tanks and 1,343 miles . . .

So far, I have driven my used 2010 Prius 1,343 miles on three fill-ups of a total of 27.35 gallons of regular unleaded fuel (10% ethanol). Those numbers yield an actual MPG of 49.10. However, in keeping with the optimistic tendency of the computer, the car calculated my mileage to equal 51.1.
#948 of 997 Brand new prius 32 MPG?
Feb 22, 2012 (1:03 pm)
I just purchased a Prius 2011 a few weeks ago, have only 200 miles and change on it and so far the MPG shows as 32.4, what am I missing? My commute is only 3 miles long each way...can someone help with some guidance?

It is your short commute (3 miles) which is hardly enough to warm up the car. On the bright side the same occurs with conventional cars except that you still get better MPG with the Prius. Take it for a long drive (a trip on the HWY and another trip in the city) and see if it is better.
Enjoy your new wheels!
#950 of 997 its the short cummute . . . sorry!

I hate to be the one to break it to you, but I found out the same thing; a short commute kills gas mileage as it takes the Prius 10 minutes or so to charge the battery so that you can run on battery assisted power. After that 5 to 10 min interval passes, your mileage will increase significantly. Take it on a long road trip and watch what happens.
