Two Year Results

That's a great lifetime for that many miles. I woud think it takes a lot of discipline to achieve that.

What type of driving, mainly freeway? At what average speed?

 

Sounds about like mine. Just passed 2 years this week.

30600 miles driven

56.1 mpg Lifetime display

54.4 mpg Lifetime calculated

407 miles per tank

7.52 gallons per tank

$2.109 per gallon average

562.384 gallons of gas = $1186

Though it seems that in addition to the SSCs and recalls, I've had more stuff replaced than you.

Replaced so far:

Center Console Cover (coming loose)
MFD (died)
Headliner (sagging)
Tail Lights (melting)
Door Sill Trim (warping)
and, last week, the HV Battery, as detailed in the other thread.

Still love the car in spite of the teething pains

 

I'm impressed not only with the MPG but the relatively few miles driven. I'm a four month owner and I'm at the 7000 mile mark. That means I'll be close to your mileage in 1 year, not 2. Thanks for sharing your stats!

 

Two years in August. Will let you know but so far so good! Will follow your example.

 

OK, without hunting through the manual to find the answer, how do I pull up the lifetime display of mpg?

Springtime

 

wow the gap between the MFD mileage and your calculated mileage seems to be a bit large.

 

Yes, but there seems to be a gap for everyone. Can anybody explain why? Surely it's not because Toyota is trying to mislead us? If not, why have they not put a correction into the software?

Or could it be because the gallon you buy is not an accurate gallon? Maybe the retailers tend to build a small error into the pump measurement so that you get say 2% less than you think you're getting. I was told once that this would be within the law because an error of +/- 5% would be acceptable in law.

 

I am averaging 51.2 mpg, without any real effort to save gas, cool in am 38-45 warm in evening 60-80. Almost all freeway driving 65-75 mph.

Still in break in period, 1100 miles.

 

I am still in break-in (just over 1000 now), but I am averaging 40.3 mpg. Mostly round trip to work (3 local, 12 hwy, 2 local). But it starts out cold in the mornings (25-35F) and under 45F every afternoon. First few miles always 25mpg, usually 50mpg at the end. Hopefully, this will significantly improve when warmer weather returns.

 

for everyone?? you might want to recheck that. there have been several posts verifying that over time, the two numbers merge so much so that many stopped tracking the pump figures. mine are much less than a ¼ mpg apart.

i do not recommend that (stopping the 3 P method; pump, paper, pen) as i used pump calculations to file a report on a pump that i suspected was shortchanging me. it was later reveled (almost a year later!!) that the pump was inaccurate but not enough to "warrant further action" after its "normally" (state law mandates every three years, it was a month short of 5 years when if finally got done) scheduled calibration.

there was also a special on the local news when an independent company went out with measuring equipment to several different gas stations. they got 5 gallons from each, all with digital pumps accurate to 1/1000ths of a gallon. meausred the volume received and found that 11% were inaccurate beyond allowable limits with 3/4 in the favor of the gas station. due to this study, they estimated that Washingtonians were paying more than $150,000 a month for gas they did not receive.

because of the way new pumps work, its nearly impossible for stations to purposefully cheat you, however there is a metering valve that does become inaccurate due to normal wear and tear which is the reason that the 3 year time limit on inspections is on the books. but in the state of WA, there is only 9 inspectors. they are way behind and average inspection time runs 4½ to 5 years between stations unless they receive multiple complaints about the same station. the station i filed a complaint against (the arco just off the courthouse exit on hiway 101) is one of the busiest, largest and cheapest in the area, centrally located between two small colleges and the associated cheaper (and crummier) than normal mostly student housing.

also the acceptable error for the state of WA is something like +/- .002 gallons...iow...practically no error allowed.

soooo, you are probably right, you are being shortchanged....stats show 1 in 13 are.

 

Since two other Toyota vehicles had that same problem, neither of which were a hybrid, it doesn't count as something related to Prius.

It's also helpful to point out that replacement cost was zero, covered under a TSB.

 

Compared to what?

The Classic had a variance of 2.0 MPG based on my 59,827 miles of data. For my HSD as of 48,820, the variance is 1.4 MPG.

Jeff's reported 1.1 MPG is pretty close, not bad at all considering the computer is estimating & rounding.

 

I said "seems that everyone" because that was the impression I had from reading PC comments. I suppose the majority of us haven't done a careful check. I've not been able to check mine yet because I haven't done enough miles to get a reliable result but it's a relief to know that the car's estimate may well be accurate.
If 1/13 are being shortchanged, how many are getting more than they pay for because of pump inaccuracies? Or are defects in pumps always in favour of the seller?
Anyway this is all fairly trivial because a 1% error in favour of the seller will cost you about 20 cents each time you fill up so in a year's motoring of say 10,000 miles, somewhere around $6 a year? Maybe the retailers deserve that!

 

actually, 1 in 13 are being shortchanged. out of the fillups, 11% were inaccurate with 3/4th of those readings being in favor of the station. now this is a random sampling of around 100 station pumps of the thousands in the state.

either way, i think you can consider the MFD very accurate.

 

What do you mean by "estimating?"

 

You forgot the nearly two tons of emissions you didn't put out.

You also forgot to mention the hard-to-evaluate "advertising" you've given the cause of environmentalism simply by driving a car everyone recognizes as a hybrid.

i still think the best part of my Prius is the calmness i feel because the car does not idle while sitting in traffic. not having that constant vibration (cant hear it since stereo of one type or another almost always on) is calming in a way i can not explain.
