Can you resist "Reset"

Well spotted, it should have said 61.2 down to 60.9 mpg. Sorry for the error.

 

Yours will automatically reset the miles driven per tank, but not the mileage. Mileage accumulates until you manually hit reset. The 2004 models automatically reset both figures.

I always reset my mileage after I refill the fuel tank. I like to know on a tank by tank basis.

My wish for the 2010 3G is for a mpg display similar to odometers on most current vehicles-- one that is not able to be reset, which would show lifetime mpg, and two re-settables, although one of the latter would satisfy 99% of us. This should be mandated for all vehicles.

I reset the MFD after every tank, and I also reset Trip A. I reset Trip B every time I change the oil. What can I say, I'm a button pusher.

 

I have not yet touched Reset after 9100 miles. Highest I saw was 50.1, now back to 49.8 as the temp has gone down. If it starts getting lower and bothering me I may succumb and hit reset.

 

I intended to not reset mine, but when I cleaned the fingerprints off the screen with the microfiber cloth there it went! Bye-bye overall MPG. Easily done, lesson learned, don't clean screen with car/MFD on.

 

I've got 13,200 miles and have yet to hit the RESET button. I'm at 46.5 mpg overall.

 

Thats one feature that I absolutely loved about the Honda Insight, it did have a lifetime MPG that could not be reset and was stuck for the life of the car. What I loved most about it is for resale value, you can tell (for the most part) how an Insight was driven by it's lifetime MPG. If it has a lifetime of upper 50's or higher, it was likely driven with care and a purpose. Low 50's and I'd be skeptical and look into it carefully, below 50 and I'd be concerned about it's condition based on how it must have been treated. A driver with low MPG likely does not show as much care for the car, dinging curbs with the wheels, door dings, scratches, less wash/waxing, etc, overall a less cared for car. One with much higher MPG obviously shows that much more care was put into it, the extra effort.

I do find this to be a "must have" feature for all high efficiency hybrids, or any car at all for that matter.

 

I just bought my car with 9 miles on it.

I have around 170 miles on the MFD and an avg of 49.5 mpg.

Just getting the hang of it. I notice when I leave in the morning and it's cold I can't get about 25mpg till it warms up.

 

I've got just over 33,000 miles on my car. I haven't hit the reset button for the past 6 or 7 months, or about 7500 miles. I've been from san jose, to eureka and back during that period and my mileage is 52.6! I love my car.

 

I reset after every fillup. I also reset the A and B trips. When I get to one bar I reset the B trip and then when I see the bar flash I reset the A so I know how far I've gone before I need fuel.

 

My coworker who also owns a prius told me never to hit reset. So I never ever did. That way it'll reflect my lifetime mpg score, which currently is 47. I'm happy with that.

 

I built a spreadsheet that calculates a weighted average of my tank averages so I know my lifetime.

Meanwhile I get the fun of trying to improve from tank to tank and getting the feedback from day to day.

 

When I was getting the first fill up for my new Prius, I thought it would be interesting to not reset the MFD for awhile and see the overall average. First, I was really surprised to see the mileage automatically reset after the fill-up. So I figured I would just leave the mpg going and not reset that. Well, I accordantly reset it about half way through that first tank. So much for that idea. Like Fibb222, and many other here, I have a spreadsheet going to track overall mpg.

 

Since there is no lifetime mpg feature on the Prius and the MFD figure inflates the real at-the-pump figures, there seems to be no reason whatsoever to resist reset. I find it much more useful to reset after fill-up and compare MFD to real @pump numbers (pretty wild, sometimes). I'm with the folks who record data on a spread sheet to obtain valid lifetime numbers.

If one strives to leave the reset 'button' at rest, what is really gained? You can't PROVE the number is real, can you?

 

Inflates?, who says?

 

I know it is not statistically significant, since I have had only two fill-ups, but the MFD mpg has been about 2% less than the calculated mpg.
Question to Prius veterans: On my first fill-up the MFD mileage reset but the mpg did not. On the second fill-up neither mileage or mpg reset. Is this typical?

 

"...Most of us find that over multiple tanks that the MFD overestimates FE by 1-2%..." - efusco.

That is my experience as well. Does yours differ?
